Tile for Screen Porch
 
Hi All,

We are adding a screen porch added on to our house and would like to tile the floor once it is finished. I found a nice "wood plank" porcelain tile that we want to lay in a herringbone pattern. The slab is new and in excellent condition with no cracks or raised surfaces. I spoke to the builder and there are no sealers or curing agents used in the slab that would have an adverse reaction to tile. I am in North Carolina where the winters will dip into the 30s but typically not any lower so I don't think freeze/thaw cycles will be a big problem. I would think that the tile would only see rain in heavy rain storms.

Can the tile just be laid directly on the slab? What kind of mortar should be used? What about grout?

Thanks everyone!

How think would you say the slab is? Imo if its 10"+ then you probably won't have to prime it 1st. A product like versabond thinset would work, I would make sure that tile doesn't have a high glaze on it or if the tile gets wet you won't slip with shoes on.

Slab is only 4" thick (except for footers)

4" seams thin to me? How big is the room. Your perimeter footing is higher then your base floor correct? If so by how much. Is the floor now smooth like garage floor or is it rough.

This started out as a patio off the back of the house. Code requires a 4" thick slab with footers extending into the soil. The footers are about 16" wide and extend down 16". The slab currently has a "broom finish".

Well imo I would prime it 1st for vapor reasons.

What would you prime it with?

I've done a few of these--in areas that freeze---

If the concrete is clean,as you had mentioned, you will be safe using a high quality modified thinset ---and a sanded grout---

I've always used Kerabond (unmodified) mixed with Keralastic---by without freeze/thaw to worry about---a good modified thinset will do fine---

Expansion joints and relief cuts must be maintained--so leave a cut row at the expansion joints and caulk those joints.

There aren't any relief joints. The slab is only 10x12'

No joints--then just tile it----

Can I lay the tiles butting up to each other to get minimal grout lines? This is a faux wood tile and I think it would look funny with obvious grout lines.

You need a grout line--the tiles will expand and contract-----without a grout line the expansion will knock the tiles loose----

What would be the smallest grout line you would recommend? I will have to use spacers as my "grout line eye" is not properly calibrated ;-).

You should make the grout lines 3/16th or 1/4" for sanded grout.
