Avoiding Cracked Tile Grout During Installation Is All About The Prep Work

A newly grouted tile floor, bathroom, or backsplash looks clean and fresh. Learning how to properly grout your own tiles can save money over hiring a pro. However, if you don't do the necessary prep work, your tile grout can crack and look amateurish.

When installing grout, it's essential to prepare it the right way. If the grout has an improper consistency, or if you apply it too thickly or too thinly, it can start to break down as it dries, resulting in cracks. Luckily, with the proper prep work, you can feel confident that the grout won't crack after installation.

What you do after installation also matters. Choosing the best grout sealer for your tile can help the grout last longer — especially in high-moisture areas like your kitchen or bathroom. And look into the easiest ways to clean grout so you can keep it looking fresh and new for longer.

The first thing to consider before applying grout is whether you've chosen the right type. Sanded grout is best for gaps wider than ⅛ inch, while unsanded grout is intended for areas smaller than that. Sanded grout is less likely to crack, but if you use it in the wrong area, it can be harder to clean off any excess than with unsanded grout.

Next, check that you're mixing the grout powder with the amount of water recommended by the manufacturer. Too little water results in dry grout that can crack and crumble, while too much water makes the grout runny. Wait 10 minutes after mixing the grout to let it set slightly, then check its consistency to see if you need to add more water.

When applying the grout, be sure to use a grout float to spread it evenly throughout the gaps between the tiles. Place a small amount of grout onto the float, then drag it along the tile edges at a 45-degree angle so the grout will spread into the gaps. Put pressure on the grout to force it between the tiles so it's installed evenly and less likely to crack.
