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.
