Orange County Floor Kitchen Bath

Right let’s sort it out, normal porcelain doesn’t need sealing. However by the way your talking you’ve got polished porcelain ,it’s easy to see the difference as polished has a flat face with a high shine and are generally big with rectified edges ( 90 degrees, not rounded) and the nice shiny smart straight lines are what probably drew you to them in the first place. Assuming they are polished then lay them with between a 2 to 3 mm gap, get yourself back down b+q and buy some 2mm spacers but when you fix your tiles don’t ram the tiles tight to the spacers but leave it so the tiles are a little ‘baggy’ if that makes sense because if you get a couple of ’sizey’ tiles you are in trouble.Don’t think ‘oh dear I’d better give them a bigger joint’ because if you do they will look crap and certainly don’t butt them together for various reasons.
When your fixing them notice whether or not they seem to be very absorbent ,if you leave a wet sponge on them for a few seconds does it immediately leave a wet mark or try putting a felt tip mark on a off cut and see if you can get it off a few hours latter.Generally polished porcelain doesn’t need sealing but some of them do.I’ve laid hundreds off these floors and probably sealed about two.You can lay your floor without sealing but keep clean and if they are porous don’t use a felt tip to mark them, use a pencil. If you do need to seal do it before grouting once the floor has completely dried and probably afterwards also.Not an easy job for an diy-er. Good luck and remember prepare your floor to get it as flat as possible ,keep your lines straight and try to get it reflecting like a mirror !

THEY SHOULD BE SEALED WITH GOATS BLOOD or mayonaise.
WHICHEVER COMES FIRST.

Like the two above, no porcelain doesn’t need to be sealed. Spacing is a bit of a personal and pragamtic choice. First, if the tile is not uniformly the same size and square, then I ‘d stay have a grout line of at least 1/8″ or so. But if you know for a fact, that tile uniform and square you can use a smaller line down to 1/32″ or so. But right up to each other no. I used a porcelain tile before that mimiced stone and used a minimal grout line. Grouted it with unsanded grout and it looked like a natural stone floor. As far as grout, general rule of thumb, under 1/8″ use unsanded, over 1/8″ use sanded. Regardless of unsanded or sanded, seal the grout. However, I recommend this product. TEC Accucolor XT. It doesn’t require sealing.

The tiles are ready sealed…and spacers will give you a far better looking finished product….Just take your time and it will look fine.

the tiles dont need to be sealed
for a more professional look i recomend using spacers and sanded grout the grout will need to be sealed for maximum durability against staining

porcelean tiles are already sealed.
you space the tiles at least 1/8 ” apart
You can use plastic spacers if you want–but it is not necessary.
Grout:: used unsanded type if 1/8 –used sanded type if 1/4 or more
Use a sealer on the grout only after everything is dry.

I have laid both porcelain and ceramic tile. Typically, neither needs to be sealed, but of course you will want to seal the grout after it has cured for a day or two.
Always use spacers, they are crucial to getting a uniform look. There are a few types, but the ones I like look like little white rubber “plus,” symbols and you determine how fat you want your grout lines depending on the size you get; it sounds like you want thin grout lines. If you want the tiles to look side to side, get a grout color that is close to the tile color. It’s all standard stuff at Home Depot or wherever you go…
