1 Prepare a safe work area
Clear and protect the work area, check the substrate and installations, and use safety glasses, gloves, and respiratory protection. Mix the material according to the technical data sheet.
⚠ Warning: Do not work on load-bearing elements, large cracks, moisture from the structure, or materials that may contain asbestos without a professional assessment.
2 Determine the condition and cause
Check the load-bearing capacity and floor heights, mark the final level with a laser or hose level, and plan expansion joints along the walls.
3 Carry out the key check
Clean the substrate, install edge insulation strip, and prepare the mix in the correct ratio. Too much water weakens the screed and increases cracking.
4 Carry out the repair or maintenance
Spread the mix between the guides, pull it off with a straightedge, and smooth it without overworking it. Cure and dry it according to the system type.
? Tip: Take a photo of the starting state and change only one thing at a time. That makes it easier to see what actually fixed the problem.
5 Test the result
After the prescribed drying time, check flatness, strength, and edges. Do not load or cover the surface with the finish layer until moisture and curing are within the allowed limits.
