Most likely we are not Talking the exact same language right here. Once i utilize the time period "subfloor", I am discussing tongue & groove plywood or OSB or regardless of what, normally 3/four" thick, especially engineered to become used on to the floor joists/fundamental construction. It truly is the continuous surface that is underneath your carpet, or your hardwood, or your vinyl, or your whatever.
You might want to understand that cement backerboards, or pretty much any tile flooring substrate, will not increase deflection balance towards your floor. That is the up and down motion with your floor whenever you wander, leap, or utilize a pogo stick on the floor.
Could you make clear modified thinset and what you are calling latex? Are you chatting latex paint or some other substance that needs to be combined in Using the thinset? Will you be indicating to paint the subfloor prior to troweling on the thinset?
Roger I would fill that with thinset and let it remedy to acquire it near to flat, then the thinset you use beneath the backer will fill it in and solidify the Room about that when it cures.
2. Get rid of the substantial ridges and sink the fasteners Verify all plywood seams that has a straightedge held perpendicular to the seams. If it teeter-totters about any joints, use a belt sander to grind down the ridge so it’s In spite of the rest of the floor. Set any “happy†nail- or screwheads.
You both equally can discredit me all you prefer; isn't going to hassle me a tad. All of that matters is some people right here will go through what I wrote, Stick to the website link I posted, and acquire stable assistance on this subject matter prior to making a error that will haunt them for years to return.

I figure the three rows of screws will permit me to pull a screed board and the screws will act like rails. I determine I can just depart the screws embedded within the cured thin established when it’s cured. Do you think that would get the job done? Thanks upfront!
I agree absolutely, and I don't Imagine I said nearly anything to the contrary. CBU's are not structural materials, they insert no stiffness nor rigidity, they just deliver an ideal substrate for appropriate adhesion of the tile. Should the underlying composition has an issue, then that the majority absolutely has to be resolved before the tile job begins.
The read more very last thing you need to do is tape your seams. Get an ‘alkali resistant’ mesh tape – similar to drywall tape – and location it above all of your seams with your floor. Then combine up some thinset and trowel it about the tape While using the flat facet within your trowel.
FWIW, I can not bear in mind a complaint of the cracked tile or hearth failure listed here within the discussion boards. For all the angst, It appears the majority are merely great and many overkilled. Â
You give plywood and contemporary design way a lot of credit history. I pity any person that follows this recommendation. I see a great deal of contemporary design that is certainly done to bare minimum code.
