• Grouting should preferably be carried out at least 24 hours after the completion of tiling. For best results use Davco® Standard Tile Grout.

All surfaces must be structurally sound, dry, clean and free from movement, oil, grease wax, curing compounds and other loose contaminating materials.

• New concrete must be allowed to cure for 28 days.
• Newly rendered surface must be allowed to cure at least 7 days.
• Steel trowel finished surfaces must be acid etched or wire-brushed prior to tiling.
• For old concrete and rendered surfaces, a strong commercial grade detergent or degreaser must be used to clean the surface to be used. Then, thoroughly remove detergent/degreaser with fresh water using high - pressure hose.
• All surfaces must be dry for at least 24 hours prior to tiling (no moisture inside), but the surface must be dampened using a sponge or cloth before application.
• Ensure all release agents are removed from concrete surfaces, especially tilt - up slabs.

Add one 25kg bag to approximately 5 to 6 liters of clean water, mixing continuously until a lump-free, creamy consistency is achieved.

Allow the mix to stand for 1-2 minutes; remix then use the adhesive. Spread the adhesive onto the substrate using either a 6mm x 6mm notched trowel for wall tiling, or 10mm x 10mm notched trowel for floor tiling. The choice of trowel should be determined by the size of the tiles, depth of knobs, grooves or ridges on the back of the tile and evenness of the substrate.

• A 6mm x 6mm notched trowel is recommended for mosaic tiles.
• Thicker bed of adhesive allow for better contact to the substrate as well as picking up unevenness especially in the case of slates.
• For tiles with deep grooves or ridges, such as slate or lugged backed tiles, the adhesive should be butter coated onto the back of the tiles in addition to being notched - trowelled onto the substrate.
• Do not spread more than 1m² of adhesive at a time. Ensure that the adhesive is wet when the tiles are laid and tapped into position to ensure that there are no voids under the tiles.
• Install tiles within the duration of the open time.
• Do not disturb or walk-on tiles until they are laid for 24 hours.
