Q. After applying two coats of DRYLOK® Latex Masonry Waterproofer, do I have to prime before putting on a decorative paint?
A. No, DRYLOK® will act as the primer for any good quality latex paint.
Q. Would DRYLOK® work to seal a crack in a basement wall foundation where water is seeping in?
A. DRYLOK® will fill fine, hairline cracks. For bigger cracks and chips in masonry, we suggest you use DRYLOK® Fast Plug®.
Q. Can I use a spray gun to apply DRYLOK® Masonry Waterproofer?
A. Yes, spray specs can be found on each DRYLOK® product page.
Q. Can DRYLOK® be used over paint?
A. No, you need to remove any existing coating. DRYLOK® works by entering the pores of the masonry and expanding as it dries to become part of the wall surface.
Q. Can DRYLOK® be used outdoors?
A. Yes, DRYLOK® can be applied to interior and exterior masonry surfaces – above or below grade.
