Palace Heat-Resist Adhesive – extended information
Coverage: When fixing on a level, even floor surface using a 10mm notched trowel, PALACE HEAT RESIST ADHESIVE will cover at a rate of about 2.5kg per sq. mtr for flat tiles on walls however when fixing heavy-duty, studded tiles on floors subject to load, a coverage rate of approximately 4.0 kg per sq. mtr should be expected.
PALACE HEAT RESIST ADHESIVE is a fast setting adhesive which cures to give a high strength durable bond in areas where tiles are fixed on solid masonry walls & floors surrounding a radiant source of heat which is not in continuous use, nor where the surface is exposed to temperatures in excess of 250’C. This includes walls & floors surrounding a domestic log burning fire, cooking range/stove or oven. It is a pale grey powder-based blend of special hydraulic binders which when mixed with water gives a non-slump fast setting paste suitable for fixing ceramic, porcelain and vitrified tiles.
Description:
PALACE HEAT RESIST ADHESIVE should only be used for fixing tiles onto solid masonry surfaces or rigidly fixed cement board structures which are stable when exposed to high temperatures. It is important to confirm that all tiles selected for use in this type of location are also similarly heat resistant.
PALACE HEAT RESIST ADHESIVE complies with the requirements of EN 12004 C2FT-S1.
Surface Preparation:
The receiving substrate must be of solid construction and stable when exposed to high temperatures. It must be clean, firm and free of dust, dirt, oil, grease and loose flaking coatings. Worn or porous surfaces should be sealed with PALACE TILERS PRIMER [SBR] diluted as 1 to 3 with water.
PALACE HEAT RESIST ADHESIVE is not recommended for application directly onto any substrate which may be subject to shrinkage, warping or any type of movement or degradation when subject to elevated temperatures likely to be reached within the intended working environment.
Mix Preparation:
PALACE HEAT RESIST ADHESIVE should be added to water in a clean container whilst mechanically stirring and mixed thoroughly to give a soft, slump-free, easily worked mortar. The recommended mixing proportions by volume are 1-part water to 3 parts powder (Approx 1.25 litres per 5kg sachet). The consistency of the paste can be adjusted with slight additions of water or powder at the initial mixing stage, however part-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 HEAT RESIST ADHESIVE will remain workable for 30 to 40 minutes and then reach final set after about 2 – 3 hours depending on site temperatures, which if high will result in shorter working time
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. Open time of the exposed mortar bed is approximately 20 minutes, depending on surface porosity and site temperatures. It is recommended that tiles with raised or studded back profiles, 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 10-minute period. When the tiled area is complete do not expose it to elevated temperatures for a minimum of 3 weeks after fixing as this will allow the adhesive and grout to cure and gain full strength without risking of being dried out too quickly
Precautions:
Due to the temperature variations & thermal stresses likely to existing in areas & locations for which this adhesive is intended, it is advisable to ensure that Movement Joints are always installed in all corners & wall to floor junctions and in any other joints abutting surrounding masonry, or over any pre-existing structural joints.
Grouting:
Grouting may proceed as soon as the tile bed is sufficiently firm, which at the earliest is 3 to 4 hours after fixing tiles. In view of the temperature range expected the use of a premium quality grout which conforms to EN13888 CG2WA such as PALACE COLOUR-LOCK is advised.
Storage & Packaging:
PALACE HEAT RESISTANT ADHESIVE is supplied in a 10kg mixing bucket in 2 x 5kg sealed sachets and has a storage life of not less than 12 months if stored in dry, un-opened conditions. Should further technical information be required, contact the Palace Technical helpline on 0151 486 6101.
