1 Prepare for safe work
Empty and protect the work area, check the base 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
Check the roof for leaks, protect your eyes, skin, and breathing, and plan safe paths along the load-bearing beams.

3 Perform the key check
Install the vapor barrier on the warm side only according to the design, and cut the wool slightly wider to fill the space without compressing it.
4 Do the repair or maintenance
Cross the layers over the beams, do not close the eave ventilation, and keep the insulation away from chimneys and hot objects according to the prescribed distance.
? 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 prescribed drying time, check flatness, strength, and edges. Do not load or seal the surface with a top coat until the moisture and bonding are within allowable limits.
