    Poorly done SLC

    Hi I got a tiler to do some works and he started to self level the area. He mixed the materials and then just poured them onto the floor without smoothing it with a trowel. He said it will “automatically” level itself out. Now it looks like some areas are raised than others and the primer has...

    Fireplace hearth

    We have opened up an old fireplace in an upstairs bedroom (it’s a Victorian house) and we’re now prepping the room for new skirting boards and carpet, but need to fix the hearth area first. I assume I need to lift out the remnants of the crumbly old hearth surround first, but how do I create a...

    Self Levelling Compound ok to lay?

    Hi, I laid Mapei self levelling compound in my kitchen and hall Wednesday morning but it still seems like areas are still damp/ not fully dry. They are hard to touch and feel the same as the other areas but are of a darker colour. They also don’t seem to be improving with a fan/heat. Reckon...

    Self levelling screed uneven edge

    Hi there, Just attempted to level a large floor area (approx 27 sqm with some deep gaps / holes) with No Nonsense 3-50mm self levelling screed from screwfix. It’s probably due to speed of work and texture difference between mixes, I found the edge between pour batches didn’t blend very...

    Self levelling compound question

    Hello all. I am planning to lay engineered floor in our bedroom but I need to prepare the existing sub-floor first. This is an old victorian house and existing floor is made of old pine floor-boards, which seem in good shape from a structural pov but does need flattening/leveling in places. My...

    Self levelling compound on a shed floor

    I have a 3m x 3m Steeltech shed in the garden which has a concrete floor. Due to bad advice from the builder I sealed the floor with PVA. On dry days it does the job fine and keeps the dust down. However as PVA (I used Evo-Stik) is not waterproof, when it's raining the PVA sticks to my wet shoes...

    Had bi folding doors installed earlier in year, pre COVID. We lifted the inside floor by installing a DPM, sandblinded to level, overlayed 100mm insulation then covered with 22mm caberdeck flooring. As the DPM covered the bottom of the door I didn't take a lot of notice as we installed the floor...

    Hello everyone, There is no mention specifically about SLC over polyethylene paints. The general consensus of leveling over paint is a no no as the adhesion is not there. I have a large area of floor that needs levelling out slightly to get rid of the ridges in the laid concrete. The concrete...
