I'm installing a laminate floor on a concrete slab - using the recommended
underlayment. I have found areas where the floor is not level and the
laminate sinks a little when you stand on it. These areas are fairly
gradual so they weren't really noticeable to the eye before I put down the
flooring - especially if you're not looking for them.
Anyway, I hadn't finished so I was able to take up some of the laminate and
I attempted to fill in the areas with a patching filler. This has not been
very successful. One area still 'sinks' and I'm finding it very difficult
to make the patching stuff level. It just ends up kind of lumpy from
sticking to the spreader as I try to smooth it out.
Does anybody have any hints or ideas on how to get around this? It may not
sound like it but usually I can manage DIY projects - but this one is just
wearing me down.
