Frequently Asked Questions
Can I put new grout on top of old grout?
The short answer is, “no.” You cannot put new grout over old grout. With regard to filling in holes and cracks on the surfaces in our homes, we might compare grout repair to drywall repair. For holes in drywall, we would simply purchase spackle, and fill the hole in.
Can a grout rake be used to replace tiles?
If you discover a place where water could be getting in, there is no point re-grouting until you have stopped the leak. To remove grout there is only really one effective tool and that is called a grout rake. It is purpose made for this job and normally features replaceable blades that can be swapped as and when existing ones wear out.
