Hello, I want to patch, for a tile, a surface of about 17M2. I have 210kg of patching compound and sand (for I know that for such a surface I have not enough product). I'm on the slab of concrete that the former owner has made. this slab is not really flat or level, there are endoits or there just to catch up 1cm each side or there are 2.5 cm. what proportions to mix (water, sand, product)? we are two people to do this work, is it enough?
I put the spray foam to fill the bottom of the walls, I carefully scanned the ground and put the graduation mark. what is the correct procedure of implementation (as I am not a mason by trade)? eceuils what to avoid? thank you cordially
hello, the slab is bare, it is impossible for me to ask because there are places to catch up or level does not go beyond 1cm each side or it is 2.5 cm which would make the fork too fragile (I've already read that on a forum here) it seems that making a cap thickness <3 cm is much too fragile.)
why I use the sand are technically and economically. you could remember the right proportions of the mixture? for example 25 kg how many kilograms of product sand and how many liters of water? the recommendations on the bag of product are not very explicit. if I have no resin is this serious? that he should aspire to the slab there is more dust thank you in advance cordially benoit
