Trying to decide best way to level an uneven tiled floor (20sq/m). Before laying Enduro pro (built in backing layer) The low areas on the tiles are no issue, as can easily be filled with flooring compound. But my issue is where there are many tiles that are just way too high. I really don't fancy screeding the whole area (20m/sq). Options: Grind back high tiled areas (is this possible?) Remove all local high tiles and fill these areas along with all the low areas. Remove all tiles (concrete floor underneath) and use a backer board to get floor height back to where it needs to be. Any advise please?
Personally, if all the tiles are solid, i'd just screed the whole area, if you take tiles out, you may loosen surrounding tiles, if you take them all up, it's messy, time consuming and you still have the time and expense of building it back up,patching it up will probably take as much time as screeding the whole area and the result would unlikely be as good
Thanks that seems to make sense. I'm a diy'er and have only sceeded small areas before so was trying to avoid the all over, thinking it may be tricky getting a good level over a large area. I'll need to do some research on methods. What the best stuff to use straight on top of ceramic? I only want to go just beyond kickers of base units. So, I need to mask it somehow with a barrier I guess?
I normally use decoraters caulk or expanding foam as a barrier, both can easily be scraped off or flush when you're done
OK, great. I have about 20sq/m. It will be min skim. So 1mm at the high points, up to 5 or 6mm where the low troughs are. What product would you guys recommend, straight on top of the ceramic (is that ok)?
Ardex NA, mapei renovation < will need priming with the renovation. Give the tiles a good scrub, degreased etc then level with the NA straight over the top if you want to skip the primer.
