Apply silicone at the back of the panel or the tile. Make sure the surface the panel or the tile is being applied to is flat and clean
Apply the panel or the tile on the wall. Repeat the 1st step with the second panel or tile. Join the two panels or tile via the tongue and groove mechanics.
Once the panels or tiles have been joined and applied on the wall, firmly apply pressure on the panels or tiles, making sure the silicone between the panles or tiles and wall is evenly spread. Let silicone dry. For bathrooms, apply a little bit of silicone in the grooves to seal the wall.
