Floor Preparation

All aspects of subfloor preparation andfloorcovering installation should be in accordancewith either BS 5325 The Installation of textilefloorcoverings or BS 8203 The Installation ofresilient floorcoverings as appropriate. During thelaying period a temperature of at least 18°C mustbe maintained and a floor temperature of at least10°C.

The type and condition of the subfloor has adirect influence on the installation andperformance of a floorcovering and theimportance of subfloor preparation cannot beemphasised too strongly.

For further information request our FloorPreparation Guide which gives comprehensiveadvice on subfloor preparation.

This includes data sheets on all the productsmentioned, giving detailed information on howthey should be used.

Concrete and Sand/ Cement Screed

These must be fully cured, sound, smooth, dryand free from laitence, dust, plaster and any othercontaminants which prevent good adhesion.

Direct to earth subfloors must incorporate aneffective damp proof membrane. Materials andmethods for damp-proofing solid floors aredescribed in BS 8102 and in Department of

Environment Leaflet 47.

New concrete and sand/cement screeds must beleft for construction moisture to dry out beforefloorcoverings are laid. For estimated dryingtimes see BS 8203. Floorcoverings should not belaid until a hygrometer test in accordance withBS 8203. Annex A Dampness Testing, gives arelative humidity reading of not more than 75%.

Damp floors may be treated with STOPGAP F75or STOPGAP F76 waterproof surface membranesas appropriate.

Uneven surfaces must be smoothed usingSTOPGAP or STYCCOSCREED smoothingunderlayment to prepare the surface foradhesive and f loorcovering.

Concrete Treatments/Coatings

Waterproofing admixtures may adversely affectadhesion and should not be used, (see BS 8203).

Chemical hardening/curing treatments should notbe used on concrete bases as there could bean interaction with the smoothing underlaymentor adhesive used. If these chemical treatments

have been used they should be mechanicallyremoved e.g. by scabbling or shotblasting thesurface before applying smoothingunderlayments or adhesives.

Concrete floor paints must be completelyremoved by mechanical methods such asscabbling or shotblasting before application ofsmoothing underlayment or adhesives.

Epoxy and polyurethane surface coatings shouldpreferably be removed, but if this is not possibleand provided they are firmly bonded, somecoatings may be primed with undilutedSTOPGAP P131 prior to skimming with theappropriate STOPGAP smoothingunderlayment. Coatings vary considerably inthis respect and we would suggest you checkadhesion by prior testing to ensure a satisfactorybond is achieved.

Non-Absorbent Surfaces

Ceramic and quarry tiles, granolithic, terrazzo andpower floated concrete slabs which have beentrowelled to produce a dense smooth surface,tend to be non-absorbent in nature. If therecommended STYCCOBOND adhesive is notsuitable for direct application to a non-absorbentsurface, then the subfloor must be skimmed witha minimum of 3mm of the appropriate STOPGAP

smoothing underlayment. Heavily glazedsurfaces should be treated to create a key forthe smoothing underlayment e.g. by scabblingor scouring with a coarse abrasive.

NOTSEW



N.B. Ceramic and quarry tiled surfaces shouldbe skimmed with the appropriate STOPGAPunderlayments to prevent the tile patterntransferring through to the surface of thefloorcovering.

Terrazzo and quarry tiles are unaffected bydampness but may be sufficiently permeable toallow the passage of moisture vapour and areoften laid in areas which do not incorporate adamp proof membrane. Where this is the case,these bases should be damp proofed bycovering with a layer of flooring grade masticasphalt complying with BS 6925.

Asphalt and STOPGAP surface waterproofmembranes must be skimmed witha minimum of 3mm of the appropriatesmoothing underlayment.

Priming

Most subfloors will require priming.

Use neat STOPGAP P131 neoprene primer onsmooth impervious subfloors prior to theapplication of the appropriate STOPGAP floorsmoothing underlayment.

Very absorbent surfaces should be primed with

dilute STYCCOBOND F70 or STOPGAP P131 orSTOPGAP P121 before the application ofadhesive or smoothing underlayment.

Existing Floorcoverings

Thermoplastic or similar floor tiles shouldpreferably be removed. However, it is possibleto install certain types of floorcovering direct tothese provided the tiles are firmly bonded tothe subfloor and all traces of polish or any other

contaminant which would prevent goodadhesion are removed e.g. with STYCCOCLEANC140 Floor Cleaner.

If this cannot be achieved the tiles must beremoved, together with the bulk of the adhesiveand the subfloor made good.

Adhesive remaining on cementitious subfloorsshould be removed by mechanical methodssuch as scraping, scabbling or shotblasting atleast until only a thin, smooth, firmly bondedresidue remains. All adhesive that is loose, lumpy,powdering, soft or water soluble must beremoved. A minimum of 3mm of the appropriateSTOPGAP underlayment should be appliedbefore the installation of the new floorcovering.

Adhesive remaining on wooden floors should beoverpinned with flooring grade plywood orhardboard (see Wooden Floors).

Any existing underlays should first be removed.

Flexible vinyl, linoleum and textile floorcoveringsmust be removed and the subfloor prepared aspreviously described before fully bondedfloorcoverings can be laid.

N.B. ‘Loose-lay’ carpet tiles may be laid direct tofirmly bonded hard floorcoverings with asuitable STYCCOBOND adhesive. The existing

flooring must be cleaned with STYCCOCLEANC140 Floor Cleaner to remove all traces of polishor any other contaminant which would preventgood adhesion. If this cannot be achieved theflooring must be removed and the subfloormade good as previously described.



Floor Preparation

Installation

Wooden Floors

Wooden Floors must be structurally sound, level,smooth, dry and clean. Adequate ventilationshould be provided to suspended timber floorsat ground level to ensure that the moisturecontent of the wood is maintained at equilibrium.Worn or uneven floorboards should either bereplaced or levelled by sanding, planing or bypatch filling with STOPGAP Green Bag & 114smoothing underlayment before finally coveringwith flooring grade plywood or hardboard.Sheets should be positioned, joints staggeredand nailed at 100mm - 150mm centres. (See BS8203 for details).

Wood blocks are not suitable for directapplication of sheet and tile flooring because ofthe continuous differential movement of theblocks and the risk of the wood block designtransferring through the floorcovering surface.Provided the wood blocks are smooth, sound,level and securely bonded, they should beoverlayed with flooring grade plywood orhardboard. Any uneven areas should first bepatch filled with STOPGAP Green Bag & 114

smoothing underlayment. Wood blocks laid onthe ground floors must have an efficient dampproof membrane incorporated in the subfloor.

If there is any doubt that all these conditions canbe met then the wood blocks must be removed,and the subfloor made good.

Textile floorcoverings may be bonded direct towood blocks with a suitable STYCCOBONDadhesive provided they are sound, level, firmlybonded and completely protected againstmoisture. Seals, polishes and any contaminantwhich will prevent good adhesion must first beremoved.

Wood mosaic panels require overpinning withflooring grade plywood or hardboard in allcases. This is not practical on solid floors andpanels should therefore be removed and thesubfloor made good as above.

If panels laid over a flexing timber floor needpatch filling, STOPGAP Green Bag & 114smoothing underlayment should be used. In allother respects wood mosaic panels should betreated as for wood blocks.

Particle boards should comply with BS EN 312-2(1997) Type P2 or BS EN 312-4 ( 1997) Type P4.

Chipboard, plywood and hardboard must be

primed with STYCCOBOND F70 or STOPGAPP131 diluted as recommended.

Composition Floors

Composition floors such as those constructedof magnesium oxychloride (magnesite) cementor polyvinyl acetate/cement will be adverselyaffected by dampness rising from the ground ifthey are covered with an impervious layer.Unless it can be established that the compositionfloor is adequately protected against risingdampness, it must be removed and the basemade good before floorcoverings are installed.If the floor is protected against dampness thencracks and small hollows should be patch filledand the whole area skimmed with a minimum of3mm of the appropriate STOPGAPunderlayment.

Double Stick Installations

Planning & Securing SecondaryBacked Carpets

There are a variety of ways to plan and securethese materials. The method described isprovided for guidance only, we cannot acceptresponsibility for workmanship and problemsarising from improper installation.

1 Wherever possible lay the floorcoveringsdown the length of the room to minimise thenumber of joints. Avoid joints in doorways

and high traffic areas.2 Measure the length of the room and cut the

carpet to suitable lengths allowing sufficientfor trimming. Ensure allowance is made forthe doorways, alcoves and any irregularitiesin the walls.

3 Position the first length, the perimeter edgelapping up the wall. Trim the carpet down theopposite selvedge using a carpet cutter ortrimming knife to leave a clean straight edge.

4 Position the second length of carpet, with theedge of the first length overlapping thesecond by approximately 50mm. Using the

trimmed edge of the first length as a guide,cut the edge and remove the surplus.

5 Fold back the edges by half the width of thecarpet taking care not to disturb thepositioning of the carpet. Apply therecommended adhesive to the subfloorusing the application technique previouslydescribed, then re-position the first piece ofcarpet and roll with a 68kg flooring roller toensure overall contact with adhesive.

6 Relay the second piece of carpet, starting atthe centre pressing the two seem edgestogether along the entire length, Any fullness

in the carpet should be dissipated away fromthe seam, and the carpet rolled.

7 Successive lengths of carpet should beinstalled as previously described. Fold backthe width of the first and last lengths adjacentto the perimeter and apply the adhesive tothe subfloor as described, re-position thecarpet and roll.

8 Using a sharp knife or Araseur trim the carpetto fit against the perimeter walls.

9 When the floor has been completelycovered re-roll the area again to maintaingood adhesive contact.

ADHESIVE APPLICATIONS

STYCCOBOND F41 is applied over the completefloor to provide a permanently tacky film whichprevents “loose lay”carpet tiles from movingunder normal traffic. Very heavy high densitytraffic such as experienced with heavy trolleysand with concentrated stiletto heel or caster chairtraffic around desks, filing cabinets, photocopiers

etc. can cause considerable damage to somecarpet tiles. It is not possible to overcome suchproblems by the use of adhesive but experiencehas shown that permanently bonding the tiles insuch areas will help to extend their life.

PLANNING AND POSITIONING TILES

The carpet tiles should be allowed to acclimatisefor at least 24 hours before installation, at thetemperature and humidity conditions likely tobe encountered during normal service. All tilesare to be laid in a tessellated effect only. Check

with the manufacturers for advice on pile-liedirections.

Lay out tiles along one wall to leave at least halfa tile border along both walls. Measure thedistance AB to give the border plus a numberof whole tiles. Measure and mark out CD on theopposite wall to the same distance as AB. Strikea chalk line between D and B. This should nowbe parallel to the long wall.

Lay out tiles along DB or measure to find outpoint E near the centre of DB which leaves aborder of at least half a tile along each side wall.

Using a T square or by measuring a 3:4:5 triangle

as on the diagram mark out the line FEG so thatit is exactly at right angles to DB.

Apply the STYCCOBOND F41 to the whole floorarea and allow to fully dry.

Place tiles accurately edged to the linecommencing at the point E. Continue placingtiles along each successive row ensuring that thefirst tile is exactly edged on line EF.

Complete this section of the floor. When placingthe tiles apply firm pressure with the palm of thehand and run the thumb around the edgesensuring complete contact with the adhesiveand the exclusion of all air. Cover the remainingsections in the same manner.

FIXING THE PERIMETER TILES

Position the tile to be cut, in its correct designdirection and place it exactly over the last tile inits row. Position another tile butted against thewall and over the tile to be cut. Mark where theback edge of the top tile crosses the tile.Remove the tiles and cut cleanly through theperimeter tile with a sharp knife. The section

furthest away from the wall should now slideforward and fit exactly into the border.

To fit around door posts, architraves etc., thesame method can be used. Alternatively anaccurate template can me made of stiffcardboard and the shape transferred to the ti lefor cutting. With the template in position on thefloor, apply several pieces of double sidedadhesive tape to its top surface. Place theperimeter tile in position and lower it on to thedouble sided tape to accurately locate thetemplate on the underside of the tile. This canthen be removed and cut into the shape of thetemplate. When the floor has been completed,roll in both directions with a 68kg flooring roller,or use a spatula as directed by the floorcoveringmanufacturer.
