How to Mix and Apply Sanded Grout
Sanded grout is a special type of grout that has small particles of silica sand in it to make it a lot stronger than regular grout. Grouting ceramic tiles may do well with regular grout, but there are some instances that require the use of stronger and more durable sanded grout. This type of grout is best to use in between tile slates, glass blocks, or any other material that has wider spaces in between. If regular grout were to be used in wide areas in need of grout, the grout will simply crack afterwards because of shrinkage. Therefore, it is important to use sanded grout in these instances. Below is a set of instructions on how to mix and apply sanded grout properly.
Step 1 – Mixing the Sanded Grout
The grout should match the color of the tile in order to create a good blend. For glass blocks, use white color. Open a bag of sanded grout and pour half of its contents into the bucket. The reason for not pouring all of the grout is to have ready supply of grout in case too much water is added into the mix. Put a small amount of water into the bucket sufficient enough to make a pasty mixture. To get the right grout consistency, follow the instructions carefully on the grout powder bag. Use a mixing knife to mix the water with the grout powder. Make sure that all the grout is made wet. Scrape the sides of the bucket to make sure. If the mix is too watery, add more grout until a consistent mixture is made.
Step 2 – Applying the Grout
Make sure that the tiles or blocks to be grouted are clean enough before applying the grout. Scoop a good amount of grout and spread it on the sides of the tiles or glass blocks. If the grout is of good consistency, it will not fall down easily when spread onto a wall. Do not put too much grout on the wall or the floor at once. Work on a portion of the floor or the wall one area at a time.
Wet the rubber float to make it easy to use. Wipe off the excess water. Use the float to go across the tiles or the blocks while pressing firmly. This motion will drive the excess grout into the large spaces in between the tiling materials.
Wet the sponge and squeeze off all the excess water. Use the sponge to go over the tiles or blocks as lightly as possible. This will remove the excess grout on the surface of the tiling materials. Rinse the sponge, squeeze off the water and go over the tiles or blocks all over again until most or all of the excess grout is removed from the surfaces. Continue in this manner until all spaces are grouted. Afterwards, allow the grout to cure.
