I would double-check the application methods for 8510. I believe only one flood coat should be applied past the saturation point at an approximate rate of 300 sf. per gallon.

Concrete or wood floor?

Gotcha. Yes, Versatile offers their 5018m polyaspartic, which comes in a matte finish. What is your intended use for the matte finish?

Acid?

Densifiers do not fix bad concrete. It would be a waste of money to apply one to concrete dusting as badly as yours. The primary problem with dusting is a weak surface layer. This is most commonly caused by too much bleed water in the mix, though it can be other issues as well. When the bleed...

I can see dusting of the exposed concrete, which is most likely why the epoxy is peeling up. Did the installer grind the floor or etch? Dusting is due to a weak surface layer, which etching won't remove. You can grind the affected area to remove the epoxy and weak surface layer (sanding won't...

Yikes... I hate hearing stories like this. I feel for your problem. This is one of two primary reasons why we have always felt that polyaspartic is not the best for a base coat. The first is that the fast cure rate does not allow for the best penetration into the concrete pores to achieve the...

Yes, a penetrating sealer is what you need. A siloxane sealer typically works best for outdoor applications. What you don't want for colored concrete are penetrating sealers that use any siliconate. They can cause surface whitening. That is why some companies do not recommend certain products...

Ahh... OK. So the concrete was integrally colored and a powdered release agent was used for stamping the surface, correct? If so, did you want a penetrating sealer to maintain the natural look or a topical sealer to enhance the color and provide more protection?

Was the release agent solvent- based?

One of the ingredients is alkyl alkoxysilane. It forms a type of micro-thin film-forming silicone used in hydrophobic coatings. The molecular structure is much larger than that of silane and can't penetrate concrete well unless the concrete is etched. Silicone also wears off quickly from...

This is the description of the Behr product in the first sentence: "The BEHR Premium Protector and Waterproofer is an interior/exterior coating" Coatings are sealers too. It's easy to get confused if you don't deal with this subject every day :beer: The article below explains the...

I'm not aware of any sealers that require etching (at least that I can remember). Etching removes much of the free lime and other minerals from the substrate at and near the surface, which most sealers require to react properly, densifiers in particular. Otherwise, they won't be very effective...

The last thing you want to do is use an etching solution on the concrete before applying a sealer. It opens the pores more and absorbs more sealer, thus making it less efficient. Power washing is about as aggressive as you want to get. If you were applying a coating, etching would generally be...

Here you go. Follow the steps and it works wonders. https://allgaragefloors.com/remove-pet-urine-odors-from-concrete/
