Sweet. Glad I watched your video before grouting my slate. You might have just saved my job.

problem wt that is that if you seal it first.. the grout would produce an weak bound and tend to come back out later.. i would clean it after and seal ..

I found that my slate floor was SO textured that even sealing the tile beforehand wasn't enough to keep the grout from being 'left behind' in all the pores and crevices...even after thorough wiping with a damp sponge. I actually had better luck using a grout bag (think of something you would use to decorate a cake, only larger and tougher). The bag applicator is much more controlled and puts the grout exactly where you want it and nowhere else.

Thanks for the most important information about laying a slate floor and thanks to the other helpful comments here as well. I'm putting one down for my parents and to date I've only used ceramics.

Seal tiles twice, they are highly absorbent, seal let dry for an HOUR in normal weather conditions,seal again, another HOUR, grout let set, next day wash off let dry and polish with cloth getting rid off cement grout leftovers and seal a third time to include grout. And once every year or so reseal cause slate, tumbled marble,travertine drys out. Louie the ceramic artisan. (scotland)

Ok diy tilers here is how to do it properly. You need to wash the slate tiles or any natural stone tile before you put the sealer on and let it dry properly, cause if you seal it before it dry out right you will lock the moisture in to the tile..and thats bad. If you seal the tile and dont wash it first the powder residue reacts with the sealer and the surface willstain like fake gold when it comes into contact with seawater, green residue etc.

@KentDoub - Excellent point as well. Sealing the entire surface as well as the joints before grouting saves the job and makes all the difference in the world!

After grouting do i use the same sealer for seling the grout or do i use a different sealer?
