How can I stop the grout @ the bottom of my shower from cracking every time I regrout it ?

Answer 1

the next time use caulking instead of grout when you repair it...it works much better

Answer 2

When you regrout you need to remove all of the old grout. They sell different tools for relatively cheap to do this. Depending on the type of grout, sanded or unsanded, you may have to switch it up. You can buy additives for dry grout that allow flexibilty so it doesnt crack and fall apart. Also, there is a type of waterproof grout you can use called spectra lock that I have in my shower. For smaller grout lines 1/16 to 3/16, you can use just about any type. You will want to let it cure first and use a grout sealer before showering.

Answer 3

Remove all the old grout before regrouting. Seal it with a membrane-forming sealer.

Answer 4

You have to either make this joint move less so the grout doesn't crack or use a flexible filler for this area.

Answer 5

Polyurethane Sealant For Concrete And Masonry is flexible and strong. Try to find some at a hardware store. Follow all the general do's and don't's before you start your repair. Hope this helps.

Answer 6

if you are refering to where the wall tile meets the floor re-grouting will not help....treat the area same as corners just use color matched caulking and all is good.
