Miracle Sealants H2O PL GAL SG 511 H20 Plus Water Based Penetrating Sealer, Gallon by Miracle Sealants

es un producto sin comparacion y muy efectivo.

Highlights: Easy to apply, cost effective compared to alternatives, LEED / Green Guard acceptable & Low VOC, Food, pet & people safe, Low odor, Long lasting warranty and does not alter color or finish. Used the "Miracle Sealants 511 H20 Plus" to seal "Microtek One Coat" Micro cement applied as a kitchen backsplash. I chose this product after many hours of research specifically because it was one of only a few options that are available with a food safe product declaration, low VOC emissions and LEED / Green Guard acceptable use. Product is water thin and can be applied by rag, Miracle Sealant applicator, brush or roller. I used "Amazon Basics Microfiber Rollers" to apply the product and in my opinion, this was the best option for a porous surface. For a polished surface a microfiber rag or the applicator tool would be best, don't forget to wipe of any excess product. In my case the very aggressive porosity of the micro cement absorbed large amounts of product and did not require wiping off access product. I plan to apply a 2nd coat and expect the need to wipe of excess product then. This did not alter the color of the substrate. I did notice initial streaking of the product, but this disappeared as I worked the product in and it dried. After curing the micro cement / substrate was noticeably less porous and smoother. I cannot attest to durability, stain defense, water beading / defense and scrub ability at this time. Coverage. I estimate that I achieved about a 400 sq. ft. coverage ratio. On a polished countertop or tile, I would expect the coverage ratio would easily be double if not triple.

Love this - so easy to use. I used a foam brush which made it very easy to apply. If you can get someone to help you wipe it up after you apply it that makes it much easier. And a little goes a long way.

It sorta works

Living in Minnesota, freeze/thaw cycles began to crack pieces of my limestone wall off due to moisture soaking deep into the limestone. This Miracle Sealants H2OPLGAL4 511 H2O works and will last for several years before needing to be reapplied. This stuff doesn't create a surface coating that will make stone look glossy or wet. You can't tell it's even on until you see water beading up on it.
