Replacing mineral grout
In many cases, unfortunately, it will be necessary to replace the grout. You can do this yourself with power tools. If we have mineral grout, we will need a tile scraper, but you can also use a special attachment for the drill. A milling tip should be able to do the job.
Removing old grout
Tools that we can use to remove old grout:
- screwdriver – this is the cheapest way to get rid of old grout, but it’s also the most time consuming, and it doesn’t give us great accuracy in our work;
- grout pick – you can also find it under the name grout scraper; it has a handle with specially sharpened tips, it is also suitable for levelling new grout afterwards;
- drill attachment – this is the most professional way to get rid of old grout, it allows for quick removal but requires some practice. Sanding bits are also available for use to get rid of crushed grout. To make the work with a drill a little faster and cleaner, it is a good idea to use a vacuum cleaner as well when sanding the old grout.
Some people also use wallpaper cutters or razor blades.
Making new grout
Once the old grout is completely gone, the surface must be thoroughly cleaned to apply the new material.
To make new grout, we need to apply a special primer to the joints between the tiles. It will help adjust the absorbency parameters of the substrate, which translates into binding of the material we use.
Then, we should start preparing mortar for grouting . First, it has to be ground in water in appropriate proportions that will allow for obtaining good consistency of the material.
A rubber float or a spatula is suitable for applying grout. The material should be scraped into the joints in such a way as not to scratch the tiles – this requires delicacy and precision. Distribute the grout with flat movements so that it fills all the gaps between the tiles. If there is too much material, you can remove it with a damp sponge once the grout has hardened slightly.
It is a good idea to apply an impregnating agent on the filled joints, which will protect them against mould and darkening. This will also make them more resistant to mechanical damage.
