Hello All, I've been working on my porch for the last few days (or trying to) installing ceramic tile. Read through all the threads and just want to make sure i'm doing this right. After installing the Hardibacker, I laid and cut all the tile I will be using. If you were to walk on some of the tiles they would wobble (uneven). From what I understand I must use a SLC to even these spots on top of the hb. How much will I expect to use and what type do you reccommend? I really don't want to spend much more $ on this project (way over buget already).
Any information will be greatly appriciated.

 

You should be able to level everything as you set the tile. Just build things up a little more with the thinset and all should be good. If there are serious out of level problems, they should have been addressed before the hardi was put down. If you used screws to secure the board there can be screws that didn't seat all the way and make the tile wobble.
You should be fine just setting the tile.
Later

Thank you Bryan for the advice....the job came out awsome.
One last thing though. We bought Glazed porcelian tile. The store suggested we use TILELAB SURFACEGARD PENETRATING SEALER to seal the grout.
I swore I read that your not supposed to use a sealer on the glazed tile?
Please help......

 

You don't want to seal the tile. You do want to seal the grout. So, they were right. Seal only the grout. It will prevent staining of the grout and some water penetration.
I personally don't like Tilelab sealers. I don't know many who do. At the HD they have two other brands both are very good. One is made by Miracle and the other by Aqua (I think). They are more expensive but well worth it.
Glad to hear the project turned out well.

I will exchange the sealer.
how should I apply the sealer? paint brush, cloth, sponge?
Just want to do it right

 

They sell a bottle applicator with a wheel on the end of it at HD. Pour the sealer in the bottle then squeeze it onto the wheel as you roll it across the grout lines.

 

sounds too easy....Thank you very much for all the help..
