This latex-based, semi-impermeable coating is guaranteed to block up to 15 psi of water pressure and is engineered to withstand category 4 hurricane winds. Whether you're sealing basement walls, foundation blocks, stucco, or poured concrete, DRYLOK Extreme penetrates and adheres to the surface to form a tough, long-lasting barrier. Its bright white, smooth flat finish is tintable, allowing for aesthetic flexibility, and the low perm rating ensures vapor resistance along with moisture protection. Application is simple—two coats by brush, roller, or sprayer—on clean, porous masonry surfaces. Touch dry in just 45 minutes and ready to recoat in 2 hours, DRYLOK Extreme allows you to finish the job in a single day. In addition to its waterproofing strength, it resists mildew growth on the dry film, reduces radon gas penetration, and can be top-coated after 24 hours. Surfaces must be free of old paint, grease, and efflorescence for proper adhesion, and cracks should be patched with DRYLOK Fast Plug. Backed by a fully transferable 15-year warranty, DRYLOK Extreme offers both peace of mind and professional-grade protection for your home or project. Ideal for anyone seeking reliable defense against water damage with minimal maintenance.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBlocks water pressure up to 15 psi and resists category 4 hurricane winds\u003c\/li\u003e\n\u003cli\u003eIdeal for masonry walls, brick, stucco, cinder blocks, and poured concrete\u003c\/li\u003e\n\u003cli\u003eSemi-impermeable coating resists moisture and vapor with less than 1 perm rating\u003c\/li\u003e\n\u003cli\u003eBright white latex base finish is smooth, tintable, and mildew resistant\u003c\/li\u003e\n\u003cli\u003eTwo easy coats applied by brush, roller, or sprayer\u003c\/li\u003e\n\u003cli\u003eDries to touch in 45 minutes and ready for second coat in 2 hours\u003c\/li\u003e\n\u003cli\u003eCan be top coated after 24 hours\u003c\/li\u003e\n\u003cli\u003eReduces radon gas penetration for improved indoor air quality\u003c\/li\u003e\n\u003cli\u003eRequires clean, porous surface and removal of efflorescence for best adhesion\u003c\/li\u003e\n\u003cli\u003eCracks and holes should be filled with DRYLOK Fast Plug before painting\u003c\/li\u003e\n\u003cli\u003eFully transferable 15-year warranty ensures long-term peace of mind\u003c\/li\u003e\n\u003cli\u003eSuitable for both interior and exterior, above or below grade applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003c\/div\u003e","brand":"DRYLOK","offers":[{"title":"1 Gallon","offer_id":43087541928007,"sku":"164364","price":43.0,"currency_code":"USD","in_stock":true},{"title":"5 Gallon","offer_id":43088352641095,"sku":"208683","price":219.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0696\/8508\/4231\/files\/drylok-extreme.jpg?v=1786722581","url":"https:\/\/www.tools4painting.com\/products\/drylok-extreme-concrete-masonry-waterproofers","provider":"Tools4Painting","version":"1.0","type":"link"}
