Can you put self leveling compound over tiles.

The amount of time that you need to wait when working with a self leveling compound once it is poured before you can lay a ceramic tile floor depends on the product that you are working with. Hi there i want to lay floorboards over underlay which is over vinyl tiles these in turn lie over concrete. To properly install a new tile surface you should remove the existing vinyl tile grind down as much of the old tile adhesive as possible and then apply the leveling compound to smooth out the surface for the new tile. Self leveling compounds can also remain glued on tools like the trowel and the bucket.

In fact the challenge is identical. After removing the vinyl sheet i found that self leveling compound was previously used. You want the floor leveling compound to just fill the recessed area and not be higher. Self leveling compound can set up and become hard fairly quick within 15 to 30 minutes after it has been mixed with water and reaches the consistency.

You can apply self leveling compound directly to hardibacker cement board or any other approved tile setting materials. In two to four hours the surface that was applied with self leveling compound can be walked on. Another issue is that kitchen units have been moved around and the layout of the kitchen changed so there are some areas that are lower now where the old kitchen units used to be placed the compound was not poured in these places so they are 1 or 2mm lower. The drywall knives are perfect tools as well.

Applying floor leveling compound is not much different than applying drywall compound over recessed seams. It can be confusing because many leveling compounds are marked as useable on a variety of surfaces including linoleum and vinyl. Ceramic floor tiles however can be used 24 hours after the self leveling compound was put on the subfloor. If it ends up higher you now have created a hump.

If you are applying the self leveling compound to a concrete floor then it is important for the concrete floor to be totally clean and free of dirt and debris.
