Ceramic Tile Adhesive - Profix PST

Preparing the Surface:

• Make sure all surfaces are clean, dry, and free from dust, grease, or loose materials.
• Profix PST can be applied directly to drywall (gypsum board) and similar substrates without priming, as long as they're dry and free from contaminants.
• You can also use Profix PST on emulsion or oily painted walls, provided the paint is dry and securely adhered to the substrate.
• Avoid placing tiles over expansion and contraction joints; use the flexible sealant Flexseal to fill these joints.

Applying the Tile Adhesive:

1. Apply a thin layer of the adhesive onto the substrate using the flat edge of a trowel.
2. Use a suitable notched trowel to comb the adhesive horizontally, creating a bed thickness of 2 - 5 mm.
3. Press the tiles onto the adhesive firmly to ensure they make good contact.
4. It's best to work in a manageable area that you can tile within the open wet time of the adhesive.
5. Leave the tiled surfaces for 24 hours before grouting.
6. For insulation polyester boards, apply 50 mm diameter spots of Profix PST at the four corners and one spot at the center of the board. Then, firmly press the board onto the substrate to ensure good contact with Profix PST.

Remember to follow these steps to effectively use Profix PST tile adhesive for your tiling projects.
