SLC on plywood or on backerboard?


Am getting ready to tile our laundry. I believe (haven't confirmed yet because its currently covered by the dryer) that one corner has a small area that may need to be leveled.

If needed, is it better to lay (thinset and screw) the backer board, then use some sort of SLC on the backer board? Or use the SLC on the plywood, then backer board?

I'm pretty sure the area would be pretty small, and I'm not sure how adding lath etc then SLC would work in such a small space.

Thanks,

Kiwi.

Hi,

Backer board then self leveling or patch. Not a good thing to nail/screw into concrete patching material.

Why use backerboard to begin with?

The Self Leveller is the backer.

Good point, but, sounds to me as only a small area needs leveling. If it ends up that the entire floor is covered with the proper thickness of SLC, then that's all that's required.

Yow I see what you mean:

Missed that part, I was thinking the whole room was getting levelled.
There would be less costly ways to flatten out that floor other than SLC at $30 per bag and primer at $15 a jug. Doesn't sound (now) like fifty pounds of SLC would be required.

Thanks for the replies. It is only a small amount that may need to be levelled and I haven't really investigated it, so you never know, it may be flat! Will be a little annoying to spend $50 to fix such a small space, but I guess you need to do it right.

I think you can buy a 25# bag of Portland cement-type floor patch for under ten bucks and fix it with that. Even then, the "fix" would go on top of the cement board.
