Hey guys, quick guestion.
I laid my first tile yesterday (pretty excited about it)! Under the tile is 1/4 backerboard and 1/2 inch plywood underneath it. I used a mortar mix using a 1/4 trowel. My question is this:
The tile has now been in place for about 15 hours. When I walk on it I can see some of the corners moving up and down a little bit. Do I just need to wait for it to set a little more before laying the grout? Is the corner movement going to be a problem - is this normal or am I heading for trouble?
Thanks - Kenny.

DID YOU SCREW AND GLUE(THIN SET) DOWN THE BACKER BOARD? WHEN YOU SAY MORTAR MIX DO YOU MEAN OUT OF A BUCKET OR DID YOU MIX IT UP FROM A BAG?

thanks for you help.
I screwd the backerboard to the 1/2 plywood. Laid and mixed powder mortar (added water) to the backerboard and laid the tile.
I'm starting to get a bad feeling about this.........

a little confused here,did you mix the thinset in a bucket or on the floor?If on the floor then you got problems.
Also 1/4 notch on the trowel is not sufficient for tile on the floor over plywood maybe concrete bit not ply.
If the corners of the tile are moving then they need to be pulled up and redone or you will have bigger problems later,tile and /or grout cracking etc.
Get back to us and let us know what you did step by step:cool:

thanks guys, Okay here is what I did step by step.
I removed the old floor discoved 1/2 plywood already down. I cut and screwd down 1/4 inch backerboard on top of the plywood.
I mixed powder mortar, in a bucket with water and stirred it until it was like a creamy peanut butter. Mortar used was Multi-purpose thin set mortar 253. (guys at lowes said this is what was needed.) I applied the mortar, already mixed to the floor with the trowle using the teeth end to rack the mortar and applied my tiles using 1/4 inch spacers. Once that section was completed, I removed the spacers and started on the next section.
the tile seems to be down pretty good but there are a few tiles where the ends are moving just a little when weight is applied to the opposite end. I'm thinking maybe when I removed the spacers I also removed some of the mortar. Not sure, I tried to be real careful.
What do you think? Would it be a major project to remove just a few tiles and reset them? Not sure how i'd do that because those babies seem like they are in pretty good! I'm hoping that a good layer of grout will solve the problem...........

well --if you didnt put thin set under the backer board between the ply wood you have a problem on your hands.After 24 hours a latex modified thin set should not be that soft that the tile is rocking.When you used the spacers did you have them laying flat between the tiles or standing up like crosses? you may have broken bond removing them if they were laing flat.(and removed to soon)
