   Brent,

   Whether you use sanded or un-sanded grout really depends on the size of your grout joint. If it's over an 1/8" then use sanded grout. . . with caution though. . . the sand could "scratch" your tile. It would be best to test this first. Also, you might want to add a like latex additive to the grout for added strength since it's on the floor.

   *I typically use sanded grout on joints 1/8" wide and wider and non-sanded on smaller joints. As Joe mentioned...make sure your tile wont scratch but assuming the tile is rated for floor use it should be OK. Sand adds strength to the grout. Mix with a latex additive and seal the joints after curing time recommended by the sealer manufacturer.Dave

   *If you get a modified grout, such as Custom's Polyblend, the most common on the west coast, do NOT use any additives. They are already in the grout mix.

   *Mike,

   Had a chance to check the six boxes of Custom's Polyblend grout I have in the shop. . . no mention of "not" to add any additives. I'm wondering were you got this info from? I use an additive sometimes with no ill effects so far.

   *Joseph:My Polyblend Sanded Tile Grout box says:Combine el relleno con agua limpia y fresca y mezcla hasta que adquiera consistencia cremosa y tersa. No use aditivos. Plain as the nose on my face.On the front of the box features listed include:Polymer-modified---just add waterPerhaps there is a difference in sanded/nonsanded, Poly may come either with or without additive, then again, you like I have trouble accepting the word "not", as in "not possible", "not enough money", or "not another whatnot honey?!"

   * Thor,

   After another inspection of the boxes of "non-sanded" grout. . . no such statements "No use aditivos." in either language! Might just be on your box. But, I'll check the sanded boxes to make sure.

   Just finishing my walkin shower. Used nonsanded grout for the walls. Thinking of using sanded on the mosaic tile on the floor. Any advise on the using sanded vs nonsanded? Thanks Brent
