After researching, testing and collecting data over the past few years we have finally comprised our list of the top concrete sealers and we have narrowed down the #1 Concrete Sealer in each category. Sealers were rated using a 5 scale system of strength, quality, durability, longevity and price. After rigorous testing and gathering results we have come to the conclusion that the sealers we are recommending will provide long lasting protection and will actually work as claimed.
#1 Decorative Sealer
With its environmentally friendly nature and higher gloss shine than your standard water based acrylics Everclear has proven to be an excellent non-yellowing decorative sealer. Standing up to harsh UV rays for a period of three years before needing a reapplication, this sealer is easily applied and reapplied right on top of the previous coat without needing to remove the previous sealer. If you are looking for LEED points on your next job, this sealer passes VOC regulations is all 50 states coming in under 100 g/L.
Our Take: It is difficult to find a good acrylic sealer that will last and hold up to sun, weathering, salt and rain. With Everclear VOX, we had no problems for three years and when it came time to reapply it was exceptionally easy.
#1 Concrete Densifier
It is very hard to distinguish the differences between concrete densifiers since they are all either sodium or lithium silicates, when polished, create a beautiful polished floor even if there was a mistake made during application. Ashford Formula has continuously proven to have a top performing densifying solution that is proven to work.
Our Take: If something is not broke, why fix it. Ashford Formula continues to be a reliable solutions for polished concrete floors with a name and brand you can trust with 60 years of proven performance.
#1 Waterproofing Sealer
With its unique proprietary formula incorporating molecular nanotechnology, Kretetek has one of the best penetrating, waterproofing sealers we have ever used. With its unique blend of silicates and siliconates, this sealer will not only densify concrete, but it will waterproof, prevent mold, mildew, efflorescence, radon and hydrostatic pressure. Its extremely versatile nature makes it an excellent choice for foundations, driveways, roof tiles, basements, sidewalks, patios and more. We were amazed with the ease of application and the natural, enhanced surface that beaded any sort of water and fluids, completely waterproofing our concrete.
Our Take: Might seem a little pricey retailing for $95.00 per gallon available at homedepot.com but since it is sold as a concentrate one gallon makes five gallons that will cover 1000 square feet. If you break down the price per gallon that is $19.00 per gallon which makes it a little easier to handle. In our opinion you cant put a price on a waterproofer that works.
