Easy to apply by brush, roll, dip, or pour, it covers up to 18.75 square feet and remains flexible in temperatures as low as 45°F, making it a reliable solution for long-term repairs. ## Description Product description Stops leaks fast. Starts out as a thick liquid and dries to a super strong, flexible, watertight, rubberized coating. Seeps into cracks and holes. Blocks out air, water, and moisture for a superior seal, virtually anywhere. Prevents rust and corrosion. Extends the life of patio furniture, pool pumps, RV and shed roofs, and more. Stands up to extreme weather changes. Expands, contracts, flexes and stretches. Resists rain, snow, sun, and hail. Exceptional adhesion. Works on all types of surfaces, even challenging ones, like metal and glass. UV and chemical resistant. Use indoors and outdoors for basement waterproofing, foundation fixes, roof repairs, and more. DIRECTIONS Fully clean and dry the surface for best results. Etch the surface to help with adhesion if needed. For the best application, use a standard disposable paint roller or paint brush. Apply several even, thin coats and wait 24 - 48 hours for each layer to fully dry before adding the next. Always place the lid back on the container after each use. If drying occurs, remove any skin before using product. Review: Great Product! Great Value! Product performs as advertised! - This is the second time I have purchased. Easy to use coverage is exact 18.75 square ft. I painted decking boards 60"x 5.5" will cover total of "8". I recommend using a brush that can be thrown away. I used a 2" all purpose polyester brush $2.99. Depending on how long project takes you might need a spare brush the paint does stiffen quickly. Cannot leave brush to come back later. Do project within an hour. If not brush will not be flexible or pliable. ( have a spare brush). I have cleaned a brush but it was very difficult to get all of the the product out of brush. The foam disposable brushes DO NOT WORK WELL! To do one quarter of a board resulted in using 2 foam brushes leaving a third heavy and crumbled. The foam becomes heavy and comes off the stick. Creating a huge mess. I have also used a small portion of can and if you make sure rim is clean clear of paint and put lid on with a hammer to assure it is closed I have gone back 6 months later and paint was useable not hard no problems ease of use as if just purchased. I've used before I actually used wrong wood and after 4 months the previous wood that I painted was great no mold no rotting. The product held up well exactly as advertised. I have applied and temp dropped to 45 degrees no problem. The picture shows proper wood. Painting front and back to avoid replacing wood again. The value of not having to replace wood especially when it will be touching ground on my ramp. Time and money a huge money saver! Hope this helps.
