I love the look of wood but don't want to incur huge expenses just to have it ruined before the life of the product is up. We do NOT like the echo of laminate so that has not been a consideration for us. So wanted to turn here for more feedback. We have been talking to various floor places for recommendations and we are getting mixed recommendations. But can't assume the problem will go away with new floors. We are not sure if the urination issue is due to old carpets stained with urine or they are just being cats. We have 3 cats which do have urination issues. We are replacing all of the carpet, which is approximately 80-90% of our home. Currently it is primarily carpet with tile in the wet areas. We are replacing flooring in our slab Texas home. I just read up about the QEP Lash Leveling option, that is pretty slick, so I may use that for good measure to prevent lippage. I could go with the 12x12 if its in the my long-term interest but the 12x24 look so much better. My home is your typical studs and vinyl siding home, sitting on concrete block.Īny input regarding adequate preparation for the 12x24 tiles would be appreciated. And "No", my home is not a mobile home, so that has me a bit concerned. It's particle board that is sprayed blue on one side. If my math is correct, this is 1/16" thinner than 3/4".

My subfloor is APA Series Blue Ribbon 24CC 23/32" "Mobile Home Flooring". There are no columns directly under the kitchen floor other than at the edges described above. There are two columns of block supporting the other 20' side and one column on the other 11' side. One 20' side and one 11' side sit on the outer perimeter of the foundation block. My kitchen is located in the back right corner of my house, on a crawl space. Went into my crawl space on a fact finding mission.įloor joists are 2 x 8 and are spaced 16" on center. With more plywood, Ditra, and the tile itself, it would be higher than the carpeting of my living room and the hardwood floor of my dining room. I really would rather not add the height another 1/2 of plywood before the Ditra. Would using a 12x12 tiles instead of 12x24 reduce the potential negative impact of imperfect subfloors? Also, still recommend another layer of plywood before the Ditra if I go with 12X12?

How do I resolve a slight low spot? Is that the purposeof the recommended second layer of 1/2 plywood? I suppose I can use more screws (if its on a joist) to lower slight high spot.

I'm not certain how to resolve these since they are so slight. I know that I have some slight high spots and dips in the subfloor. I don't know what you mean about the "unsupported span of the joists."ĭo you mean the greatest distance between where the joist rest on the concrete block foundation around the perimter and the smaller stacks of block scattered throughout the crawl? This weekend I will get in the crawl space and measure the distance between each joist and the height and thickness of the joists. Additionally, cement board adds no structural strength but takes up more height. Ditra does a better job of uncoupling the subfloor movement than does the cement board. It would be better for you to use ditra (over a second layer of plywood), than cement board. Consider using a leveling system like the Lash System for minimizing lippage. It'll depend if they are cupped, tile size consistency, how flat the floor is, what the edges of the tile look like and maybe some other factors. Minimum grout joint size for these tiles is probably 3/16" or bigger. If the tiles are cupped, they will not match up well and you may have to rethink your pattern. You can do this by doing a test layout on a dead flat surface, and checking the height of the tiles where 2 ends meet the middle of the tile next to them. If you will be installing the tile in a brick pattern, you will want to check the tile to make sure they are perfectly flat.

You want to resolve any high spots or dips in the floor before you install the ditra. Consider adding an additional 1/2" of exterior glue plywood over the subfloor, and then using ditra.įor that size tile, you will need a dead flat floor, and little to no movement. Give us the details as to the joist size, on center spacing and unsupported span of the joists. Its a great product.įor tile that size, you will want a proper joist structure and substrate. I will tell you that Ditra is a product that has been around for many years and there are many miles of successful installations out there. I have never used it and so cannot comment on its performance. I think the membrane you are talking about is Custom Building Products "SpiderWeb".
