PALACE GYP-BOND is a calcium sulphate based one Part Flexible Rapid Setting tile adhesive for fixing ceramic, natural stone & porcelain tiles to floors & walls which are gypsum-based, i.e. Anhydrite floor screeds or Calcium Sulphate (Gypsum based) wall plasters. This enables a direct bond to be formed without the need for applying a pre-sealing barrier. It sets within 1 hour and will support light foot traffic after 3 hours. PALACE GYP-BOND incorporates a high polymer loading and can be applied over anhydrite floors where sub-floor heating is in use or to be applied.
- Fast setting adhesive allows grouting 3 hours after fixing
- Fixes Ceramic Porcelain & Natural stone tiles to Gypsum walls & floors
- Forms a direct bond without the need for a pre-sealing barrier
- Recommended for Interior application in dry locations, not exposed to water
- Fixes natural stone tiles such a quarry, travertine & terracotta
Surface Preparation: The receiving floor surface must be hard, sound and free from grease, dust, floor, efflorescence and loose deleterious materials such as worn surface coatings & plaster laitance. In addition to suitable prepared & dry anhydrite & gypsum-based surfaces PALACE GYP-BOND to non-cement based Tile Backer boards, (including Gypsum based boards), finishing plaster & bare plasterboards. It is NOT suitable for fixing directly to any cement-based screed, concrete base or cement-based / coated tile backer boards. Anhydrite screeds receiving tiles fixed with should be allowed sufficient time to dry out, tested in accordance with BS8203:2001, will give results < 85% RH which may normally require at 20˚C 60% RH 1day/mm up to a 40mm depth and a further 0.5 days/mm if >40mm depth. Anhydrite screed will require sanding & vacuuming to remove all laitance and can be carried out when the screed base is 7–10 days in place to assist drying. Even when dry, Anhydrite & Gypsum-based surfaces can still be very porous & absorbent, therefore it is still advisable to coat the surface with PALACE TILERS PRIMER diluted 1 to 3 with water, as this will reduce suction & optimise coverage. NOTE: Palace Gyp-Bond is NOT recommended for use on surfaces in, locations that are likely to become frequently wet (showers, pool-sides, wet rooms etc). This adhesive is specifically developed only for fixing tiles onto gypsum-based substrates in DRY areas, where this is not the case then a cement-based adhesive should be used.
Mix Preparation: PALACE GYP-BOND should be added to water in a clean container whilst mechanically stirring and mixed thoroughly to give a smooth, soft, slump-free, easily worked mortar. The recommended mixing proportions by volume are 1-part water to 3 parts powder (Approximately 5 litres per 20kg sack). The consistency of the paste can be adjusted with slight additions of water or powder at the initial mixing stage, however, partly used adhesive should never be “freshened up” with later water additions but should always be discarded once it appears to lose its’ workability. In ideal conditions (20’C room temperature), PALACE GYP-BOND will remain workable for up to 1 hour at 20’C and then reach the final set after 3 hours, after which time it is sufficiently well cured to permit grout application on both walls & floors.
Application Method: For fixing ceramic tiles or mosaics, use a notched trowel to give a ribbed mortar bed on the substrate, into which the tiles are firmly bedded with a twist and slide action to ensure full contact. Use a 3mm x 3mm notch at 6mm centres for mosaics and thin flat-backed wall tiling, a 5mm x 5mm notch at 10mm centres for general wall tiling and 10mm x 10mm notch at 16mm centres for floor tiling. The position of the tiles can be adjusted up to 10 minutes after initial fixing. The open time of the exposed mortar bed is approximately 30 minutes, depending on surface porosity and site temperatures. It is recommended that tiles with raised or studded back profiles, (or in situations where dampness is likely after tiling), should be back-buttered to ensure solid bed fixing. Do not trowel out an area of adhesive greater than can be tiled over within a 30-minute period. Uneven anhydrite-based floor surfaces should be prepared with PALACE GYP-LEVEL floor smoothing & levelling compound. Do not mix or apply PALACE GYPBOND when air or ground temperatures are forecast to be below 5’C or greater than 35’C at any time during the first 24 hours after application.
Coverage: When fixing on a level, even surface using a 10mm notched trowel, PALACE GYP-BOND will cover at a rate of about 4kg per sq. meter for heavy-duty, studded tiles. When applying wall tiles, the product will cover at about 2.5 kg per sq. meter.
Grouting: Grouting may proceed as soon as the tile bed is sufficiently firm, which for PALACE GYP-BOND will be after 3 hours at room temperature. This period however will be extended in cold conditions. When the adhesive is fully set, wall & floor joints can be grouted using PALACE COLOUR-LOCK GROUT or PALACE ANTI-MOULD GROUT, however, on wider flooring applications, joints of up to 20mm wide can be grouted using PALACE WIDE JOINT FLEXI FLOOR TILE GROUT.
Storage & Packaging: PALACE GYP-BOND is supplied in 20kg multi-ply, moisture-resistant paper sacks and has a storage life of not less than 12 months if stored in dry, unopened conditions.
