Brand New... Correct Grout Spacing

I am getting ready to start my first tile install. 8x48 porcelain tile from Spain.

I was told spacing should be 2-3mm. Which I assume means 1/8" spacers. What happens if I wanted 1/16 spacers instead? Thanks in advance - I love this forum.

Welcome, Donald.

I would say you could just keep that on your want list and use the more reasonable spacing recommended by the manufacturer. The rule of thumb in the industry is that the grout joint should be three times the difference in size between the largest a smallest tiles in your layout.

While the 1/16th" spacing might be possible if your tiles are near perfectly rectified (cut to size and shape), it's something that would give even an experienced setter a bit of trouble. I'd say a 1/8th" joint is the smallest you should try.

My opinion; worth price charged.

You could compromise if you really wanted to and use 3/32 purple spacers.

I'm assuming from the size that it's probably a wood-look plank tile. I would recommend going with the 1/8" grout joint but finding a grout that looks very similar in color to the predominant tone in the tile. That way it will blend and the grout joint won't be emphasized. Here is some more information on wood plank tile installations:

White or Gray Thinset

Why one color vs another? My tile is opaque. Gray is cheaper.

Donald, it'll help if you'll keep all your project questions on one thread so folks can see what you're working on and what's been previously asked and answered. We can give it a more generic title any time you'd like to suggest one.

You wouldn't need white thinset mortar for your application. Gray will be fine.

White costs more to manufacturer due to the extra material costs among other factors.

My opinion; worth price charged.

It was recommended to me to use white if it is a natural stain due to staining potential. Outside of that, I would say it matters not.

Typically white mortar is used for glass tile, light marble, and some other natural stones. For a typical glazed porcelain, the color of the mortar will be irrelevant.

Raise a low spot?

House is on a raised foundation. I put down 3/4 in plywood over sub floor...glued and screwed. Part of the floor dips 3/8 in in a hallway Rest of the floor is flat. Can I just put some thin 3/8 plywood on the part of the floor that dips? It would be on top of existing plywood floor.

I will be using Strata Mat as well. I hope this makes sense.

I don't think that will work well, I would use a patching or feathering compound that can be used over ply without having to use lathe. You will most likely need to use a corresponding primer depending on the product you use.

Products like our Planipatch are designed for this type of application.
