How to prepare surfaces for ProSet SS

The surface being adhered to must be clean, firm, dry, free of dust, dirt, oils and grease and be strong enough to support the weight of the adhesive and tiles being fixed. To encourage best adhesion to your substrate it is advisable when applying adhesive to porous surfaces that the area is primed. Ultra Tile Prime IT FP is an ideal surface primer; as it will help to prevent water penetration, and increase bond strength. On non-porous surfaces use the recommended Ultra Floor primer from the Prime IT range.

How to mix ProSet SS

Ultra Tile ProSet SS should be added slowly to clean water and mixed thoroughly to give a slump free easily worked mortar. Once mixed the mortar is immediately ready for use and has a pot life of approximately 2 hours at 20°C. Mix only sufficient material to be used within the pot life, do not remix or re-wet. Approx. mixing ratio of 5.5-5.9 litres per 20kg.

How to apply ProSet SS

Apply the adhesive to a thickness of 3mm-12mm up to 1m2 at a time. On internal walls use a notched trowel, leaving solid ribs i.e. 3mm x 3mm at 6mm centres for mosaics, 5mm x 5mm at 10mm centres for wall tiles and 8mm x 8mm at 16mm centres for floor tiles. On floors and external areas, use the solid bed trowel method. Large studded tiles should be ‘buttered’. Bed the tiles in with a slight twisting action. Leave spaces between the tiles for grouting (approximately 1mm-3mm for walls and 2mm-20mm for floors). Clean off excess adhesive from the tile face and grout lines with a damp cloth before it sets.
