The exterior wall of a 40-year-old unheated garage is made of 38 cm masonry (inside – clay bricks, outside on the street – silicate, except for the top 2 rows of eaves). Roofing flat – roofing felt on reinforced concrete slab, without organized drainage. As a result, the brick under the eaves is damaged (photo of last year is attached, now it is much worse). The following treatment is planned:
1. Make organized guttering.
2. Remove the damaged layer of masonry.
Treat the masonry with something antifungal, then hydrophobic. This may be in one bottle.
4. In the wall, after drilling, hammer bushings for screws, on which to fix the extraction-cutting mesh under the plaster.
5. Plastering KNAUF Unterputz UP-210.
