Pot Life @ 20°C: Up to 4 hours
Bed Thickness: 2-6mm
Approximate Coverage: Walls: approx 3Kg/m2 . Floors: Approx. 4Kg/m2
Suitable Trowels: Walls: Dry areas: 6mm round notches . Wet Areas: 10mm tapering notches . Mosaics: 4mm square notches . Floors: 20mm round notches.


All surfaces should be dry, clean and strong enough to support the tiles to be fixed. Tiling substrates should be true and flat to permit fixing without visible lipping of tile edges. On floors, any gaps exceeding 3mm under a 2 metre straight edge should be corrected using NX 3-50mm Levelling Compound. This will be particularly appropriate where larger tiles or those with rectified edges are being installed. Porous or dusty surfaces must be sealed using NX Multi-Purpose Primer diluted 1:4 with water.

Concrete/Cement: Sand Screed

New concrete floors must be allowed to dry for a minimum of 6 weeks. Residual traces of laitance and curing agents should be mechanically removed before tiling commences. Screeds should be a minimum of 21 days old.

Cement: Sand Render

Must be at least 14 days old. New render should not be applied to new masonry walls until 6 weeks after the brick or blockwork has been completed. This allows for drying shrinkage to have taken place. In cold conditions these times will be extended.

Anhydrite & Hemihydrite (Gypsum) Screeds

These must be cured to their respective manufacturers’ directions before tiling can begin. The surface must be free from laitance and primed using progressively stronger coats of NX Multi-Purpose Primer as follows: Diluted 1: 4 parts water. Allow to dry. Diluted 1: 3 parts water. Allow to dry. Diluted 1: 2 parts. Allow to dry.

Heated Floors (Dense Construction)

NX Standard Set Flexible S1 Wall & Floor Tile Adhesive is suitable for use with underfloor and undertile heating systems.

On solid floor structures after tiling, the floors should not be switched on for at least 14 days and then brought up to operating temperature gradually during the initial heating of the floor. Undertile heating cables and mats can be tiled directly or prior to tiling they can be bedded into a screed of NX 3-50mm Levelling Compound. This method prevents damage to the heating elements during the laying process.

Vinyl Tiles / Asphalt

Must be sound & in good condition. Prime with undiluted Multi Purpose Primer & allow to dry.

Gypsum Plasterboard**

Seal with NX Multi-Purpose Primer prior to tiling.

Gypsum Plaster**

Must be sealed with NX Multi-Purpose Primer before tiling. If finishing plaster is polished, rub down to form a key before priming.

Existing Glazed Tiles

Must be well fixed and able to support the additional weight of tiling. Thoroughly clean and degrease & allow to dry before brush applying a slurry bonding coat consisting of 2 parts adhesive: 1 part Multi Purpose Primer Allow to dry.

Plywood Overlay On Existing Timber Floors (WBP/Marine grade)**

All sheets should be a minimum of 15-18mm thick and be screwed down to existing boards and joists with staggered joints at 300mm centres and 150mm centres along board edges. The sheets must be sealed on the back, face and edges with NX Multi- Purpose Primer. All timber constructions must be adequately ventilated behind to prevent atmospheric moisture distortion and warpage of the boards themselves.

**In wet areas or those with intermittent wetting such as showers, moisture sensitive backgrounds such as plaster should be tanked using a suitable tanking membrane

NX Standard Set Flexible S1 Tile Adhesive MIXING

Into a clean pail add 1 part of cold water and gradually introduce approximately 3.5 parts of adhesive powder stirring to blend the mixed mortar to a smooth lump free consistency. The properly mixed mortar will be thick enough to hold the adhesive ribs without slumping. Mix only enough material that can be used within the pot life of the product which will be around 4 hours – this will be extended in cold conditions and reduced in hot weather/ warm temperatures.


Using a suitably notched trowel spread the adhesive onto the fixing surface to form parallel ribs into which the tiles should be applied with a firm twisting action. Spread only enough material that remains workable and as such fully wets out on the tile backing. Solid-bed void-free fixing will be necessary on floors and in wet areas. Tile with deeply keyed back profiles may need to be back buttered. The adhesive is designed for thin bed fixing up to 10mm although in isolated areas it can be bedded out up to 12mm in thickness. Tiles may be grouted as soon as the adhesive bed is set. Under normal conditions this will be around 16 – 24 hours after fixing although this will be extended in cold conditions. Do not use below 5°C.


Store in dry internal conditions away from direct sunlight between 5-35°C. The product has a 12 month shelf life from date of manufacture.

BTP very helpful in supplying a pallet of floor leveller. I needed it on the Saturday, but didn’t want it sitting on the driveway for several days. I called and they recommended ordering for Thursday to give a day’s grace in case of any delivery issues. In the event the pallet arrived on Thursday as requested. Reliable and good value
