On vertical surfaces apply grout upward.
How to apply grout on tile wall.
Next apply the grout to the tile working from the bottom of the section upwards and holding the float at an angle of about 45 degrees.
Work in a small area at a time roughly a 3 x 3 foot section.
The thickness of your joint will determine if you can use sanded or unsanded grout.
Additionally spread the grout into the joints and use the side of your float to compress it.
Use this method for both pre mixed and powdered grout.
Use the float to make sure that every joint is full of grout.
Wider than 1 8 use sanded.
When it comes to how to apply tile grout to a wall firstly apply a minimum amount of grout to the front surface of the tiles with a trowel and spread it with a grout spreader.
Apply the grout with a rubber grout float filling the joints over a 5 to 10 square foot area.
Do not cover the entire float with grout.
Mix to a smooth like toothpaste consistency let sit for five minutes then mix again.
How did this project turn out.
Mix the grout by pouring the water in first and then add the powder and stir with a margin trowel.
Begin by scooping up a load of grout onto the grout float using one end of the float.
Spread the material in sweeping arcs pressing it into the joints to fill them completely.
Keep applying the grout until the mixture in the joint starts to set.
Then mix your grout until it s smooth and spread it across one section with a trowel.
Always try to grout diagonally across the tiles so the mixture goes into the gaps.
The best technique to use is to adopt long strokes that have an upwards and diagonal direction making sure it spreads completely in between the joints of your tiles.
Pour a quart to half gallon of grout on the tiles.
Use a hard edged rubber grout float and hold it at a 45 degree angle.
Use whichever side or corner of the float is necessary to fully compress grout into the entire joint.
If the joint is less than 1 8 use unsanded.
