what type of board and thickness is applied to a bathroom floor prior to laying tiles.?

Answer 1

I think that it would be best to put down some marine plywood. It is a little more expensive, but will last in the long run.

Answer 2

A sealer or adhesive is pretty much a must if you want the floor to last, because raw floors have alot of dust even after sweeping. Just make sure the floor is sound, if not, drive screws every 6 to 8 " especially along the edges. Be sure to fill all holes and the edges with putty and sand smooth. If you don't, your tile will eventually crack and start coming apart at those areas. Armstrong makes 2 products that work great. You can use Armstrong Floor Primer (latex primer, looks like milk, soaks in and settles the dust, makes a nice surface to adhere the tile to, but note, this is not paint, or paint primer, this is made for exactly what you are doing and about $10 a gallon) or even better, use Armstrong Floor tile Adhesive($20 gallon), it states on the can that it makes for an excellent primer for self adhesive floor tile. You must roll or brush the primer on and use a trowel to apply the adhesive. The adhesive must dry tacky before starting, and can stand for 24 hrs should you not finish. the primer only takes a few minutes. Either way everything is on the back of the can. Good luck

Answer 3

You will require 3-6mm plywood screw down in to floor boards and check it is level. You will require flexible adhesive and grout to use with laying the tiles as this allows for movement of the wooden floor. It stops the tiles from popping up or cracking. Some adhesive do require the floor to be primed first always read the packet of adhesive before buying. Good luck

Answer 4

Hardy backer board works, but you should use cement board. They come in half and quarter inch thickness. Half is what you want, but if you want the floor lower, you can get away with quarter inch. The best way to set the cement board is use the cheap thin set with a very small trowel. A carpet glue trowel works best. Then stick some inch and a quarter galvanized roofing nails about 8 inches apart. You want to use mesh tape and thin set to cover the joints. If you are putting tile on the walls, you should take down the drywall and put up half inch cement board directly on the studs, with glue inbetween. Always use the galvanized nails, because the water from the thin set will rust them. There is glue you can use to set wall tile that is a lot easier to work with.

Answer 5

It's called concrete backer board. It comes in 2 different thickness, and if you ask at Lowe's, Home Depot, etc..they will tell you which will be best for your project:) It is the BEST thing to put down before tiling..it will keep your tiles from moving, grout cracks, etc, and is waterproof. It's not overly expensive either, and not too difficult to put down:)
Good Luck!!

Answer 6

depends on the tile that you are using but if its ceramic you don't use wood you use hardybacker or a concrete board. If wood gets wet it swells and will pop all the tiles up.

Answer 7

It depends how firm the existing floor is, but at least 10mm ply, and ideally 12mm, SCREWED at 100mm centres, not nailed. No need to use tile backer unless you are putting electric underfloor heating in.

Answer 8

You probably want concrete backerboard. You need to decide the thickness - is there an existing floor underneath? is the floor warped or uneven?

Answer 9

6mm if the boards are reasonably flat, 10mm if not, screw at 150mm centres using screws no longer than 20mm for 6mm ply and 25mm for 10mm ply or you might hit hidden pipes or cables. prime ply with a pva glue 1 part pva 2 parts water. use a flexible adhesive to lay tiles. good luck.

Answer 10

some barmy answers here! Use 6mm pylwood screw it to the floor every 6-7inches.When you tile make sure you use the right products,primer, flexible adheves and grouts, most tile shops will supply and advise.
