SURFACE PREPARATION

Surface should be clean and dry, free from dust, dirt, and other foreign matter. It is important to dampen the substrate prior to the application of the tile adhesive.

APPLICATION SCHEDULE

For Heavy-Duty Applications

Mix a 25-kg bag of K-302 All-Purpose Tile Adhesive with 6-Liters of clean water in a clean container. Add at least ¼ Liters of K-321 Tile Adhesion Promoter and stir with a mixing device until desirable consistency is achieved.
Dampen the substrate prior to application of product. Using a notched trowel, spread the adhesive around a square meter at a time. Apply to desired level to smoothen any uneven surfaces. Place and align tiles. Adjust height accordingly by gently tapping the tiles using a rubber mallet. Fix tiles immediately within the 15-minute open time.

For Tile-on-Tile Applications

Mix 1-Liter of K-321 Tile Adhesion Promoter, 1-Liter of clean water, and 3-kg of K-302 All-Purpose Tile Adhesive in a clean container. After attaining the desired consistency, apply the mixture using a brush on the existing tiles. Let the mixture dry for 3 to 4 hours or overnight before tiling.
For horizontal application, add ¼ Liter of K-321 Tile Adhesion Promoter per 25-kg bag of K-302 All-Purpose Tile Adhesive
For vertical application, add ½ Liter of K-321 Tile Adhesion Promoter per 25-kg bag of K-302 All-Purpose Tile Adhesive.
Using a notched trowel, spread the adhesive a square meter at a time. Apply up to 3mm minimum thickness.
