Step 3: Applying Adhesive for Mounting Wall Tiles
It is important to select a right adhesive for the substrate you're using. You
must carefully read and follow all instructions and precautions on the adhesive or mortar package. Mix
adequate amount of adhesives that are enough to use within thirty minutes. Using the type trowel recommended on the adhesive package, spread a 1/4" coat on the surface of one grid area.
Make sure do not cover guidelines. Next, use the notched side of trowel to comb adhesive into standing ridges by holding trowel at a 45-degree angle.
Remove any excess adhesive, leaving a uniform, ridged setting bed. Don't over spread area
that can not be set in 15 minutes.
Step 4: Cutting Tiles for Wall Installation
You should measure tiles to be cut carefully and mark the cutting lines with a pencil.
Straight or diagonal cuts should be made using a professional tile cutter.
Using curved cuts with a nipper to chip away small pieces for best results.
Using a rod saw to make full-length curved cuts. Smoothing sharp-cut edges with a carborundum stone.
Step 5: Setting Tile on the Wall
Variation of shades is an inherent characteristic of ceramic or natural stone
tiles tile. Make sure to mix tiles from several batches as you set for create a blended effect.
Installing tiles one grid at a time. Finish each grid before moving to the next. Start with the first tile in the corner of the grid and work outward. Set tiles one at a time using a slight twisting motion. Don't slide tiles into place. Insert tile spacers as each tile is set, or leave equal joints between tiles. Fit perimeter tiles in each grid last, leaving 1/4" gap between tile and wall. When grid is completely installed, tap in all tiles with a rubber mallet or hammer and wood block, to ensure a good bond and level plane. Remove excess adhesive from joints with a putty knife, and from tile with a damp sponge.
Step 6: Grouting Joints After Setting Tiles
In general you should wait about 24 hours before grouting the joints. The adhesive package
should have specific instructions. Carefully read and follow all instructions
and precautions on the grout package. Prepare grout little bit a time, enough to use in about 30 minutes.
To apply grout, remove tile spacers and spread grout on the tile surface, forcing down into joints with a rubber grout float or squeegee. Tilt the float at a 45-degree angle. Remove excess grout from surface immediately with the edge of float. Tilt it at a 90-degree angle and scrape it diagonally across tiles. Wait 15-20 minutes for grout to set slightly, use a damp sponge to clean grout residue from surface and smooth the grout joints. Rinse sponge frequently and change water as needed. Let dry until grout is hard and haze forms on tile surface, then polish with a soft cloth. Rinse again with sponge and clean water if necessary. Don't apply sealers or polishes for three weeks.
In the case that sealing or final polishing is needed, do it in accordance with manufacturer's recommendations
