Know the difference between grout and caulk.

Grout is sort of a cement mostly applied between tiles, it does not support movement. When it comes to preventing your bathroom from cracking, you will sure want to know the two differences.

When the grout is used around the bathroom, it mostly requires sealing to enable it to stay waterproof.

On the other hand, caulk aims for flexibility and is best designed for bathrooms because of its waterproof nature.

You can have your caulk spreading around your bathtub rim to stop water from licking into walls and floors.

When you are ready to take a shower, and you fill the tub and then get inside it, the applied caulk should be able to sustain the pressure it is receiving.

• Don’t use the two in the same position.
As most people are doing, the grout is used to fill the small gaps between the tiles but after you are done, you will want to leave some margin in order to apply the caulk in the bottom edge.

A good example is my bathroom, it is filled with grout in between the tiles but as you keep on moving to where the shower bed meets bottom tiles at the perimeter, I added caulk and it was truly a nice idea.

You probably wondering why your caulk keeps on cracking forcing you into re-caulking process.

The reason why caulk is cracking is because of the water that penetrates into the ground, filling up the area under the tiles.

In wet areas, caulk starts to peel off as this encourages the growth of moulds.

This results in adhesive weakening that was initially applied under the tile.

When the temperature around the area is dry, you will notice gaps around the shower corner, this is because the caulk has shrunk and cracked leaving those spaces that will lead to mould development due to the stagnant water.
