Installation Guide:

There are some key points you need to pay attention to when installing Altro safety flooring:

• Make sure that you select the right product for the area type • Make sure that you select the right adhesive for the area type • The flooring joints must always be hot welded to make sure that your use the correct tools for grooving, hot welding and trimming • The floor must always be protected from other trades using the correct covering of non-staining floor protection.


• Altri safety flooring should be laid as in the Code of Practice BS 8203:2001+A1:2009. • Store the materials for about 24 hours at room temperature and not below 14°C. The area must be at steady temperature between 14°C and 27°C for at least 48 hours prior to, during and at least 24 hours after completion. • Before adhering to subfloor, make sure that the materials are checked for any faults and cut into lengths and laid loose for conditioning for at least 2 hours. This is because the warranty for colour, batch or obvious material defect is only valid before the flooring is permanently bonded. • In order to remove any tension of the materials, before scribing, make sure you “back roll” or “dress” the materials. • All the materials used in one area must be from the same manufacturing batch. • All the sheets must be laid in the same direction. • Make sure you match Altro safety flooring with patterns from sheet to sheet.


• Check the requirements for subfloor with BS 8203:2001+A1:2009.


• Make sure you choose the correct AltroFix™ adhesive (you can check from Altro data sheets adhesives on their website). • Removed any excess acrylic adhesive with cloth with neutral detergent and alcohol for two component adhesives. • When removing excess adhesive, make sure it is still wet and must be done while work is still on progress.


• For areas that are prone to water spillage, complete installation must be sealed, for example with the usage of conventional clamping or welding type drain gulleys and access covers, sealing of pipes, toilet pans, door frames and any other sealing methods between the junction of flooring and wall. Check with Altro detail diagram sheet. • After that, the joints can be cut before or after the application of adhesive. However, bear in mind that if the joint is cut before applying adhesive, there must be no movements from the sheet while placing it to the adhesive or there will be problems. • Turn back the material, apply the adhesive on the subfloor, depending on the type of subfloor, this might take a while. • Place the floor back to the subfloor and remember to push it to remove any trapped air bubble. • Remove excess adhesive immediately. • Roll the whole area with a floor roller. • Any joints within the sheet must be cut in, grooved and hot welded.


• Cut a 3mm groove evenly along each floor joint (except internal/external mitres), using a hand rotary grooving tool or automatic rotary grooving tool. We recommend to use special Altro automatic grooving blades since regular blades can be quickly destroyed when being used on safety flooring.

Forming a hot welded joint

• After the sheet vinyl flooring is cut and laid to adhered subfloor, you must hot weld any joints with Altro Weldrod™, using a 5mm high speed welding nozzle hot air welding gun. • Hot weld internal and external mitres. • To make sure the adhesive is set correctly, let it sit for 12 hours after laying and before welding. However, this does not apply when installing Altro XpressLay™. You can weld immediately after installation since there’s not wet adhesive used.


• Weld the internal and external mitres on the coved sections. • Make sure you turn the speed nozzle at the end of the welding gun to up position. Or you can always use Altro coving speed nozzle. • After you finish welding the mitres, hot weld the groove floor joints by turning the nozzle to down position.


• When cooled and mounted, cut the weld with the most appropriate tool, like a spatula fitted with a spatula guide or slit. • Then cut the weld flush with the flooring material on the ground using the spatula only. The square router blade is used for external miters and the rounder blade is used for internal miters. • The Altro T20 chisel was particularly designed to remove excess weldrod for Altro MarineTM 20 security flooring. Refer to the data sheet of Altro’s recommended equipment and tools for information on equipment and tools.

Protection and maintenance

• Make sure you cover and protect your Altro safety flooring for any other trades using the appropriate non-staining protective covering. Refer to Altro’s cleaning and maintenance for recommendations.

Laying Altro Static Dissipative safety flooring

• Install the Altro Walkway™ 20SD using the same procedure with standard sheet. However, only use recommended conductive adhesives.

How To Install Tarkett?

1. Transport and Storage

• Store all the rolls and boxes in a clean and dry indoor place and free from pollution • Store rolls with 2ml width in upright position and safely secured • Store rolls with dimension above 2ml horizontally • Store tiles flat in their package, piled neatly not more than 5 boxes high, protected from extreme temperature, moist, rust, rot, free from any contamination and do not put under heavy weight. • Store rolls and tiles 48 hours prior installation. • For linoleum, keep the room temperature above 15°c or 18°c during installation. However, do check with your country’s rules and temperatures might be different in different countries. • Take out sheets and tiles from the packaging 24 hours prior installation.

2. Handling

• Use only manufacturer’s recommended tools and accessories for handling all types of floorcoverings to avoid any damage to the material or people. • Materials must always be checked for any defects or damage before and during installation and report to Tarkett representative. • Install the same batch number and roll/boxes in sequential order for continuous surface • Remember Tarkett does not guarantee any problems caused by inappropriate storage or handling

3. Subfloor Control

• Ensure that your subfloor is in good condition, i.e. flat, clean, free from any debris or residues, no marks (of felt pen or marker or ballpoint pens or paints), dry, solid, hard, smooth. Because the number 1 factor for successful installation is the subfloor quality. • Check the absorbency level and subfloor should not be exposed to humidity. • Always follow your country standard of use for preparation of the subfloor and installation procedures. Solid subfloor’s dryness must be below the maximum moisture level allowed. • Use a non-oily pencil for markings.

Subfloor Characteristics

Humidity Rate

• Always refer to regulations in your country (for relative humidity test, calcium carbide system, etc). • It takes approximately 2 weeks per cm for a concrete floor to dry. • Remember, Tarkett does not guarantee any disbanding, bubbles, colour migration caused by excessive humidity rate.

Absorbency – Porosity

• If the absorbency time of a drop of water is less than one minute, then the subfloor is too absorbent, which means you need to apply primer before leveling compound, with 1:1 dilution. • If the absorbency time of a drop of water is more than 10 or fifteen minutes, then the subfloor is non-absorbent, which means you need to apply non-diluted primer. • Trouble might occur in the bond plane duet to longer waiting time of the adhesive in non-absorbent subfloor, while too absorbent subfloor could cause dis-bonding issue due to shorter waiting time of the adhesive.

Planarity / Flatness

• Different country has different ways for measuring. In UK, tolerance must be less than 3mm over 2m for concrete/wood subfloor (and it also depends on localities, SR1 or 2). • Visual issues or additional cost for using more leveling compound could occur if the surface is not flat.

Cracks and Joints

• Cracks: 1.3 to 1mm large. During the concrete drying process by contraction, cracks can appear. • Micro cracks: less than 1.3mm large (almost not visible). • Expansion Joints: used to compensate dimensional variations and building movements. • Isolating joints: separate the screed from other independent building constructions (walls, pillar). • Contraction (dividing) joints: allow free contraction of concrete and avoid cracks during drying. • Construction Joints: used to stop daily pouring of concrete slab.


• You must treat micro cracks with a primer. • You must cut, clean and fill cracks and construction joints with epoxy resin on which sand will be spread. • You must fill contraction joints with epoxy resin on which sand will be spread. • Treat expansion joint with an inserted or overlapped profile. • Stop levelling compound and floorcovering on both sides. • Fill isolating joints with soft material like polystyrene.


• To ensure that your subfloor is resistant enough to compression and indentation, use a sclerometer to measure the hardness of the concrete. • Heavy traffic or weight on subfloor that is not hard enough could cause damage on leveling compound which results in visual/technical defects.


• To avoid colour migration and any other damage, ensure that the subfloor is free from contaminants like hydrocarbon stains, paints, chemical residues or laitance on the surface.


• To avoid visual defect/telegraphing effect, ensure that the subfloor is free from any particles, dust, traces of felt pen or marker.

Subfloor types - Preparation

New Subfloor

• Preparation for Concrete/cement base Use water base primer compound and self levelling compound which is adjusted to the level of traffic • Preparation for Wood or wood particles/plywood base It is recommended to use primer compound which can adapt to wood and can be install directly. Alternatively, you can add a special wood fiber levelling compound. Remember to check the thickness and length, any opening, glued groove and tongues caulking of joints and smoothing. • Preparation for Bitumen base Use primer that is emulsified with neoprene vinyl or alternatively use primer + self levelling compound that can adapt to bitumen • Preparation for Anhydrite base (humidity rate < 0.5% CM) Smooth the surface prior applying adapted primer or emulsion. It does not require any screeding • Preparation for Metal Clean the subfloor from any oily residue then apply an anti-rust primer + gluing.

Old Subfloor (Renovation)

Preparation for terrazzo or ceramic tiles: • Ensure that all tiles are still securely fixed to subfloor. • Remove surface coating or sealer by applying emulsified primer and adapted self levelling compound.

Preparation for Wood parquet (glued, not floating): • Ensure that all planks and pieces are solid and well-fixed to subfloor prior applying primer or adapted emulsion and fibre reinforced self levelling compound.

Preparation: • 1st check that all wood planks and pieces are well in place, solid and securely fixed, then apply a primer or wood adapted emulsion + fibre reinforced self levelling compound NOT recommended for HOMOGENEOUS Vinyl Products.

Old Floorcovering

Textile: • Prior to applying an adapted self levelling compound, any textile must be removed and scraped.

Vinyl: • Prior to applying an emulsified primer and adapted self levelling compound, any old flooring must be removed and scraped, especially for heavy duty usage • However, if the old flooring is HO compact vinyl floorings or VCT type that are still in good condition and well-fixed to subfloor and only in small area, it may be possible to install without removing the old floorings. There are two ways to do it: • Prior to installation, do thorough cleaning and degreasing of surface then apply PVC adapted acrylic base adhesive on PVC installation. • Prior to installation, do thorough cleaning and degrasing of surface then apply cement base levelling compound, in accordance to recommendations by manufacturer.

Underfloor heating

• Heating must be stopped at least 48 hours before screeding and installing floorcovering • After installation, restart heating Stop heating at least 48h before screeding and/or floorcovering installation. • Re-start heating gradually (few degrees per day) 48h after installation (few degrees per day). • Vinyl tiles should be hot welded • Maintain the temperature between 18°c to 27°C for installation.

Primer (solvent/water based, PU, Epoxy): • Apply primer with a brush or roller. Consumption can vary between 80 to 120 g/m2, depending on the planarity of the subfloor. • Never apply a leveling compound without applying primer before, otherwise delamination or cracks of the levelling compound may occur.

Materials for Installation

Self-levelling compound: • Cement based compound with smoothing finish for indoor use which will be covered by floorcovering. • Average consumption is 1.5 Kg / 1 mm / m². • Heavy duty = 2-3 mm thickness.

Adhesive: • Ensure you only use adhesive recommended by Tarkett.

Some key points you need to pay attention to: • Check adhesive compatibility with flooring product backing (PVC, PU, jute, etc) • Check the aspect of backing (rough, smooth, fibers, grid, etc) • Check the flooring porosity (textile, jute, etc) • Check the subfloor porosity, whether it is absorbent or not • Check the quality and performance (polyvalence, the consumption, etc).

• For linoleum, use a notched trowel. Ensure you use appropriate type according to the backing. For jute backing, you need  300g/m2 – 350g/m2, using B1 spatula (TKB model). For foam backing, you need  200g/m2 – 300g/m2, using A2 spatula (TKB model).

4. Installation – General Rules


• Install the sheets parallel to incoming light in reasonable square rooms. • Install the sheets along the length of the room in long, narrow rooms. • Joints must be placed at door step • Ensure you place the sheets with the right layout. • Draw a reference line and align the sheet edge to reference line. • Cut sections of flooring to required length, adding a few centimeters. • To install, first you either half fold or roll the sheets in all sections and then spread the adhesive using the right spatula. Make sure you don’t over glue or let space without adhesive. • Fold back the sheet in first section into the adhesive while pressing it using the cork press to get rid of air bubble under the sheets • Repeat for the rest of sections and the second half of the folded/rolled sheets. • After you done gluing and pressing all sheets, trim any excess of materials close to walls and obstacle, using either knife or hook and concave blades (freehand cut) • After that, press all floors using heavy roller (min 50kg) to ensure the floors are well secured.


• First measure the room the installation is about to commence • Draw the reference axes to determine the layout. You will work per section (quarter) that has been divided by the axes • You can shift the reference line when needed (example when cut off is too short) • Start working in the 1st quarter by applying the appropriate adhesive to the first section, using the right tool • Place the tile in below sequence:

For diagonal installation, follow the picture below:

• When installation in a quarter is done, start scribing excessive materials. • Continue with the rest of the quarters and then press the whole installation using heavy roller (min. 50kg) to ensure the floorings is securely fixed.

Joints Welding:

• You could either do hot welding (suitable for all types of flooring) or wet welding (suitable for PVC HE only).

Hot Welding:

• First groove the materials appropriately. • Make sure the deepness is 2/3 of the thickness for compact, till foam for acoustic and till jute for linoleum with max 2.5mm. • Use hot speed nozzle, with exception for linoleum you use open nozzle. • Keep the temperature between 350 – 400°C for hot speed nozzle and 500 – 550°C for open nozzle, with speed of ± 2ml/min. • The trimming guide is 0.5 for compact and 0.7 for acoustic.

Cold Welding:

• Must be done min 24 hours after installation. • Ensure you get the potential pattern match by overlapping the 2 sheets. • Double cut the overlapping in one or two steps, in case of a think flooring alongside a metal ruler. Ensure the end result is an extremely tight joint. • Apply a special masking tape. Make sure you put in the center over the cut seam. • With a rolling knife, cut the masking tape within the seam prior to applying the cold-welding liquid by pressing the needle deeply into the seam. • Ensure you apply enough cold-welding liquid along the joint. • Remove the masking tape carefully backwards after the cold-welding liquid is dry (approximately after 10 minutes). • Do not walk on the seam 24 hour after cold-welding.

5. After installation, there are few points you need to remember:

• Always check for any adhesive marks, stains and dust and clean them all. • Protect the area to prevent soiling. • Do not expose the area to any traffic 48 hours after installation. For furnitures, move them only after 72 hours.

How To Install Karndean?

Some key points you need to pay attention to: • Adhesive must be put within the open time stated on the adhesive box • After installation, all products must be rolled with a 68kg roller. For smaller areas use a small hand roller. • All tiles and planks must be left untouched or protected from direct contact 24 hours after installation. If you use pressure sensitive adhesives, the tiles and planks can have direct contact immediately after installation. • Please note that MLC01, MLC07, MLC08, MX92, MX93, MX95, MX97, MX98 are directional. To make sure the fitting is uniform, T101 and T102 requires to be tessellated.

Acclimatisation of Material Before Installation The material must be spread out and placed flat in a room with constant temperature of 18°-26°C for 24 hours before installation takes place, during installation and 24 hours after installation.

Laying Karndean Over Various Floor Types

Installing Karndean over Sub-floors

When installing products, ensure that the sub-floors moisture level is below 75%RH (tested with hygrometer in accordance with BS8203-4; 2001). If the moisture level exceeds 75%RH, you need to install a surface damp proof membrane (DPM).

Concrete/Sand Cement Screeds (New)

For new concrete floors, the moisture level must not exceed 75%RH (dry). The floor must be cleaned to eliminate contamination. After that, concrete floors must be applied with appropriate smoothing compound with minimum 3mm thickness. If the moisture level is above 75%, you should consult with your supplier regarding the needs of DPM installation.

Power Floated Concrete

For power floated concrete which moisture level is below 75%RH, it needs abrasion before applying a primer and must be applied with appropriate smoothing compound with minimum 3mm thickness. If it below 75%RH, it needs abrasion before a DPM is applied to.

Quarry Tile/Mosaic/Terrazzo/Ceramics

Test the floor for any dampness and contact your supplier for consultation should there be any dampness. Check for any unstable, loose or broken tiles on the floor area and remove them if there’s any. Deep holes must then be filled with rapid drying mortar. The floors’ surface must be degreased, washed and scrapped before applying primer and compatible smoothing compound with minimum 3mm thickness. For old tile, you may need to apply a second topcoat of primer and smoothing compound to eliminate sinking of smoothing compound over the grout lines.


Degrease and then rinse the surface with clear water before applying primer and compatible smoothing compound with minimum 4mm thickness.

Standard Floorboards/Tongue and Groove

Secure the floorboards, fasten the loose boards and replace any broken boards prior to setting a minimum 6mm flooring grade plywood, fixing at maximum 150mm centers. After that a full coat of Karndean skim coat can be applied over the plywood.

Undulating or Flexible Timber Floors

Apply a primer over the plywood and coat of fibre reinforced smoothing compound with minimum 3mm thickness for undulating timber floors.

All Chipboard/MDF/Weyrock

Overlay with flooring grade plywood of 6mm set to a maximum center of 150mm before applying full coat of Karndean skim coat.

Wood Mosaic Panel, Woodblock, Wood Strip

These materials should not be overlaid with waterproof vinyl, thus if you found any of these products installed directly to the ground/asphalt/pitch you should remove them. Check if all flooring fit securely if it installed onto a wooden floor and treat them as timber floors.

Flooring Grade Plywood Floors

For smooth joints and fixings in plywood, you can either apply a full coat of Karndean skim coat or apply primer and coat of fibre reindorced smoothing compound with minimum 3mm thickness. Treat any plywood floors less than 6mm thick as chipboard.


Remove any laminate floor coverings together with any underlay and laminate flooring accessories. The subfloor should be treated according to the exposed subfloor.

Metal Floors

Contact your local supplier for consultation.

Painted Floors

Remove all paint back to its original base pri,e using machine before applying 3mm thickness of compatible smoothing compound.


Remove any adhesive residue. The floor should be treated according to the subfloor exposed.

Miscellaneous Floors Including magnecite, granwood, anhydrite

Contact your local supplier for consultation.

Existing Floor Coverings (Linoleum, PVC, Thermoplastic)

Remove the existing floor covering and any adhesives residues. The floor should be treated according to the subfloor exposed.

Underfloor Heating (all types)

To make sure the surface temperature is not above 27°C (80°F), the materials must be insulated. Switch off the underfloor heating 48 hours before, during and after the installation then increased to working temperature gradually. Only use Karndean Temperature or epoxy adhesives.

Electrical Underfloor Heating (extra information)

Check with your underfoor heating manufacturer to see if the system is compatible with Karndean flooring. For concrete and timber constructions sub floors, you must coil the wire system into a base layer of reinforced fibre smoothing compound to conceal the cable. A second coat of primer and reinforced fibre smoothing compound must be applied as a finish coat. Apply surface with primer and compatible smoothing compound of minimum 3mm thickness for underfloor heating pipes that are set into concrete.

For any further instructions, consult Karndean or your local supplier.

Consult Karndean

Recommended Adhesives

Only use these adhesive below for all Karndean flooring products. Remember to use an A2 trowel to apply all Karndean adhesives.

Epoxy Resin

In order to keep real wood flooring looking like new it requires frequent maintenance including sanding, staining and lacquering. With Karndean, there’s no sanding, staining or lacquering required – it’s easy to maintain and keep clean. Learn more on our cleaning and maintenance page.

Karndean v Stone and Ceramic Tiles

Natural stone and ceramic flooring can be hard to manage and weight is often a problem, especially if you’re looking to install in a room upstairs. Karndean is much lighter, flexible and easier to install. The cold touch of stone and marble can be a bit off-putting first thing in the morning or in cold weather. Karndean flooring is much warmer underfoot and is also compatible with underfloor heating. Natural stone and ceramic tiles can be slippery when wet. Karndean flooring is fully slip tested and its textured surfaces are suitable for commercial and domestic use, even in areas which get wet, like the bathroom, kitchen, hall or utility room.

Karndean v Carpet

Our floors do not harbour dust mites or bacteria – unlike carpets. Karndean is easy and simple to keep clean, especially if you are busy, have children or pets to clean up after. Our residential guarantee covers the lifetime of your floor for up to 35 years. Unlike carpets, Karndean can be laid over underfloor heating systems. In the unlikely event of damage it is possible to replace a plank or tile of Karndean, a huge advantage over carpet which would need to be completely replaced.

Karndean v Laminate and Engineered Wood

Laminates and Engineered Woods are known for looking manufactured and unrealistic in comparison to real wood flooring. Karndean’s product designers beautifully replicate the look and feel of real wood products using advanced manufacturing techniques giving you the look of natural timber without the practical difficulties of maintaining wood flooring. Many man made materials, including laminate, can curl or shrink whereas our floors maintain their shape throughout their lifetime. If water gets inside a Laminate or Engineered Hardwood floor, it can cause the top layer of the product to de-laminate and peel making it less suitable for wet areas such as kitchens and bathrooms. Karndean Designflooring is water resistant and perfect to use in any room of your home, including kitchens and bathrooms.
