I accidentally bought a 50 gauge fiberglass fleece (instead of a 25 gauge) for the ceiling. Can you advise on the ceiling will hold or it is better to change to a fiberglass fleece density of 25. Another question – is it better to prime the ceiling diluted adhesive or primer?
The ceiling of concrete slabs plastered and putty, small cracks in the joints.
If there are cracks in the plaster after drying, the cracks should be opened, primed and sealed before puttying.
If the likelihood of cracks remain (the house is undergoing repair work, new construction), sealing cracks should be carried out with reinforcing paper. In no case reinforce with serpentine. It is absolutely useless.
