While renovating your commercial spaces, there may arise the need to level an existing concrete surface with self-levelling concrete. Here are tips to help you work with self-levelling concrete.
1) Use Caulk and Tape
The concrete is capable of flowing into even the tiniest opening. Proactively imprinting the holes or cracks in the wood with a marker or tape will keep them shut. You will have to use caulk gun to seal all the holes on the surface before you pour the self-levelling concrete. Select a good type of caulk to fill up the holes, usually, the one that goes clear from white when it dries and is visible when it sets. An additional precaution to take is taping over the caulk to avoid stepping into the wet material and to track the filled areas around the area.
2) Use Sill Sealer for the Walls
To avoid any liquid underlayment escaping into the basement area of exterior walls or other adjacent rooms, use a sill sealer between the bottom wall plate and foundation. Tall sill sealers work better as they provide protection from splashes on painted walls. Attach staples to the sealer to keep them in place.
3) Use Primer for the Wood
Primer prevents swelling of the wood caused by the water-saturated concrete. Swollen wood can cause cracks to form in the underlayment and tiles as it proceeds to shrink as it dries. The primer can be applied with ease and it would prevent the wood from absorbing the water.
4) Install Lathe
Strength to the underlayment is added by the lathe which can be installed under or over the mat and cables. Keeping the lathe flat prevents it from rising above the depth of your pour. Checking the continuity of the heating cables or mats is recommended before starting the mix.
5) Quantify the Leveller
Stick a mixer into a bucket of water and self-levelling concrete. While not in use, the bags of leveller should be placed on a pallet or sheet of plywood to prevent any moisture from the ground ruining the leveller. Always buy 20% self-levelling concrete to avoid running out of it while pouring.
6) Set the Buckets
Before you begin the mixing, place the buckets close to each other to avoid any spillage and fill the appropriate amount of water with the mixer. Going back to mixing the first bucket will stir up any settled particles.
7) Pour with Caution
While you pour the self-levelling concrete, resist the urge to wipe off any wet drops which may have splashed on the walls. Rather, you can let them dry and scrape them off to keep the smudges off the bay. As you pour the concrete, make sure the thickness of the leveller remains as much you require for the project. You can check the desired thickness with the help of a tape measure, gauge rake or a mere popsicle stick.
