Apply Porcelain Plus on the substrate by using a suitable trowel depending on the tile size (preferably a 12 mm notched trowel for a slab), then comb it in one direction. Apply Porcelain Plus on the slab’s backside using the flat edge of the trowel but do not comb (Back buttering). Install the slab in its place then tap and press firmly (or use a tile fixing vibrator) to ensure that the tile is sitting on the substrate with the maximum coverage and contact between the tile’s back and the adhesive on the substrate.
Do not apply Porcelain Plus on an area that takes more than 15 minutes to be tiled!
A useful practice to check application efficiency is to remove a slab directly after application and observe the contact surface (adhesive on substrate and the back of the slab). This can be done randomly from the applicator’s perspective and then reinstalled. This should always be done for the first slab to give the applicator an idea of how much adhesive is needed for the best contact.
Recommended coverage is more than 90% for external use and more than 80% for internal use. The slab position can be adjusted without losing any adhesion for 15 minutes.
Leave installed tiles undisturbed for at least 24 hours. Porcelain Plus must not rise between the tile joints higher than half to two-thirds of the thickness of the porcelain slab tiles.
It is recommended to use Vetonit Tile Grout to fill the joint gaps 2 days after tile installation.
- Low temperatures and high air humidity will retard the curing and drying process and vice versa.
- The best coverage can be achieved on flat surfaces.
