How to replace old wall tiles grout.

Removing and replacing grout or raking out as it is known is not a nice job. Match the caulk at most tile specialty shops you can get or order sanded caulk most floor grouts are sanded that will closely match your existing grout color. The old grout might be moldy and beyond cleanable. If the width is 1 8 of an inch or smaller use an unsanded grout.

The existing grout color is no longer pleasing to you and you wish to change it. Once you have properly mixed the grout in a bucket apply it with a plastic towel then use a grout float to press the mortar deeply into the joints. Run the tool guides between the tiles and grind through the old grout. This is where the grout saw comes in handy.

Renewing old grout has always involved long hours of hacking away at old worn grout with a tiny grout saw. If the space is larger than 1 8 of an inch use a sanded grout. Then dip a clean toothbrush in the mixture and scrub the damaged grout until all the dirt and grime comes off. Measure the space between the tiles.

As you do this hold the float at a 45 degree. This fix is only practical for interior tile floors and when the gaps between the tiles are 1 4 in. One way to change grout color is to colorize existing grout. Clean the damaged grout with white vinegar and water.

Choose the correct type of grout based on the width of your tile joints and where the repair is being done. Like with the multi tool stop every so often to sweep the dust away so you can see what you are doing. That way you can see the exact color of the grout and buy new grout that matches it. Simplify the job by purchasing a grout removal kit that attaches to a dremel tool.

Clean joints with a grout saw. It lets you work up close to the edges without damaging the tiles. Care must be taken to avoid damaging the tiles and it is very repetitive the old grout must be removed to a depth of at least 2mm preferably 3mm for re grouting to work properly. Finally wipe away excess water or grout with an old towel or rag.

Some areas of grout will be difficult to reach with the multi tool. Use a spray bottle and some cold water to wet the areas where you removed the grout. Mix one part white vinegar and one part water in a bowl or bucket. This will remove the grout you freed with the grout saw.

Then take an old toothbrush and scrub the seams.
