1 Prepare for safe work
Empty and protect the work area, check the substrate and utilities, and use goggles, gloves, and respiratory protection. Mix the material according to the technical data sheet.
⚠ Warning: Do not treat load-bearing elements, large cracks, structural moisture, and materials that may contain asbestos without a professional assessment.
2 Determine the condition and cause
Mark the ends and monitor if the width changes. A stepped, widening, or growing crack requires an assessment of the cause before cosmetic repair.
3 Perform the key check
Open only stable surface cracks into a slight V-profile, remove dust, and apply an appropriate primer.
4 Do the repair or maintenance
Fill with repair mortar in layers, embed mesh if necessary, sand, and finish with paint only after complete drying.
? Tip: Photograph the initial state and change only one thing at a time. This makes it easier to determine what really solved the problem.
5 Test the result
After the specified drying time, check alignment, strength, and edges. Do not load or seal the surface with a top coat until the moisture and bonding are within permitted limits.
