how do i prepare polished stone (terazzo) tiles for lvt

hi i have been asked to quote on 250m2 lvt to go over the top of poished stone tiles the customers syas there about 30mm thick so got to go over the top. its going to be used for a restaurant. all advice welcomed

 

Degrease, prime and screed.

 

maybe use lvt clic?

 

I'd score them up with a grinder or copper disc first.

 

Degrease Ardex na for me

 

I did a similar job recently. About 1500sq m. I had Uzin out to write me a spec, which was
L3 system primer (dpm type)
L3 gold latex.
I laid about 200sq. m on the first day. Some of it failed.
A long story short, we had to hire in grinders, scratch it up to give a key. Some even failed after that.
If I were doing it again, I would scratch with a diamond grinder. Prime with something like Primgrip, then latex.
I think I would also ask advice from Fball or Ardex. Even though I rate there product, I would not trust Uzin to do this again.

 

Everyone says about na being soft and myself to no it is but on the flyer for ardex I saw the other month said they had just used it on one of the major airports

 

So scarification is needed? Can you hire scarifiers? I have only done about 5 lvt jobs and they have all been domestic so this scares me slightly lol

 

Jumpax !! Ideal for situations like this.

 

Yes, most hire places have them. There is a charge to hire the machine, then a charge per mm for the disc
