sand & mortor basement question
hi,
my house is over 130 yrs old. i've lived in it
for 17 yrs. when i bought my house, we rented
a paint sprayer and painted the basement walls-which
are made os stone and mortor. now the paint is peeling
and mold and mildew is appearing. parts of the walls are
breaking down a bit, (little holes), it's an overwhelming job
to do, to repair all the cracks with fresh mortor, i know i can
use clorox and water to get rid of the mold. i guess my question
is. is there a product that is kind of like glue, that i can paint
on, after i get rid of the mold, that will help stop the sand/mortor
from breaking down?
thanks

Welcome to the forum,
Deterioration of mortar and brick or stone joints in a subterranean wall such as yours is the result of water present and coming through the wall.
In order to repair the interior, the water source needs to be removed from the outside, first.
Gutters and downspouts directing water away from the dwelling, proper grading of the soil to direct water away, french drains, water control upstream of the house such as a swale, and exterior waterproofing on the wall are all part of the solution to the water problem.
After that, the wall will remain dry inside and can be cleaned with a stiff brush, the mildew killed and removed, the joints repointed as needed, priming and painting as desired.
In short, nothing you can put on the inside will keep the water out from the outside.
Hope this helps.
