is there a masonry primer paint
Loxon Concrete & Masonry Primer - This is generally the go-to product when you're painting any type of masonry. It seals and adheres to concrete, block, plaster, brick, stucco, fiber cement siding and EIFS exterior insulated siding. It is highly efflorescence resistant and can be applied to surfaces with a pH as high as 13, which means you can use it on masonry that has been curing for a minimum of just 7 days.
