Is acrylic floor sealer the same as the kit that you mix for cement floors?

the salesman said the only difference was the ';sprinkles'; you can add to the paint and a cleanerIs acrylic floor sealer the same as the kit that you mix for cement floors?
You can buy both products in acrylic or water-based forms. However, there are more differences than the ';sprinkles'; (which you don't mix in the paint they are sprinkled over the surface and server no purpose but to look nice and help hide the overlap areas because you roll the epoxy in 4 by 4 sections) and the cleaner (which isn't actually a cleaner it's an etching solution that make the concrete porous enough to allow the epoxy kits to stick) One major difference is sealers tend to only be clear, with the exception of a few exterior ';sealers'; which have color and behave similar to concrete stains. The Epoxy's typically come in gray and tan and can be mixed in a variety of colors (rustoleum epoxyshield offers about 30). Another difference is you can buy exterior sealers but epoxy's can't be left exposedto the elements they have to be covered. Also, sealers wear off and need to be reapplied, usually every 5 to 10 years, epoxy's if they are applied properly, shouldn't chip, flake or wear, though like all paints they are susceptible to fading.

no they are not.


an acrylic floor sealer is a finish that employs the use of acrylic resins - these resins are stable on alkaline surfaces (concrete is alkaline, measuring ~10 pH) and very resilient to UV rays. These resins form films by entangling with one another - this entanglement allows for some flexibility, and increases abrasion resistance (the idea that it will bend, not break is a good analogy).





the ';kit'; you are referring to is probably an epoxy resin system, which is a very stable resin under most chemicals you would encounter at the interior of a home - it is however, subject to chalking and fade when exposed to UV light - not a good idea to apply outside, unless it is top coated with an aliphatic urethane.


these epoxies come in kits because they form films by covalently bonding the resins in part A with the components of part B of the ';kit';. The A %26amp; B are packaged separately so that this reaction does not take place while it is sitting on the shelf waiting to be sold. These films are extremely durable, particularly on impact - like dropped tools and abrasion - like sliding furniture.





now the sprinkles -


obviously these are added to help decrease the slipperiness of a smooth coating. you can broadcast these over both films while wet, or add to the epoxy mixture before applying it - it does not bond with any portion of the coating, but actually gets embedded in dried film - since the epoxy will almost always provide a ';thicker'; coat than the acrylic, you stand a better chance of successfully using these sprinkles in the epoxy system.





hope this helps -
