W.R. Meadows Cure/Sealer

[bfarroo]

The concrete company I'm planning on using offers a cure/sealer with their concrete installation it is W.R. Meadows CS309-25. What do you think?

it sounds good...they make a great joint seal, but that is all I know that they made.

I emailed them a few questions as with my research and readings I was leaning toward a densifier and want to know if I could either apply a densifier on top of the cure/sealer or if I should put on a densifier instead. I know there are some advantages to using the cure on new concrete and don't want to loose those.

Cure/seal is film forming. Once applied, densifier application would be impossible without stripping or sanding.

Since this will be a workshop floor that I do not ever intend on putting any sort of epoxy coating on and my main consern is to protect the floor from stains and keep it looking as good as a shop floor can be. Is the cure/seal a good product to use or would a densifier be better?

What kind of workshop? My experience with acrylic sealers on a garage workshop floor subject to gas/oil/petroleum solvents spills hasn't been good. It doesn't withstand them well. Gasoline will dissolve it almost immediately and wiping up the spills gets you a sticky mess on the wiping cloth and no more sealer on the floor. I used a densifier on my recently built shop floor. However, it hasn't been in use long enough to comment on it's ability to resist absorbing oils/gas. I don't think it'll be that good. That's not it's primary purpose.

Cure/Sealers help retard the "hydration" of the concrete. This helps to keep cracking minimized. Once the curing part is done the sealer is ok but not the best available.

A densifier is a treatment. It makes your good concrete better.
It penetrates and makes the surface "denser". It will not keep stains from occurring but may lessen the stain, depending on the type of spill. It also retards "hydration" but not as well as the cure/sealer product.

Acrylic sealers provide a true topical barrier to staining, much better in this department then densifier. Our HD6600 is about the best acrylic available and does much better in garages then other designs.

The next step from here is WB epoxy, then solids epoxy, urethanes, PAPs, etc...

Actually, I think they facilitate hydration, rather than retard it, by preventing the loss of moisture through evaporation from the surface.

I talked with the concrete guys and they can do the densifier for and upgrade charge of 150. What do you guys think? From my reading the densifier seems like the way to go. The shop will be for working on cars from body work to changing engines. And will get gas, oil, antifreeze Ect spilled on it although I do try to wipe any spills up as soon as I can.

Bob you are correct. Unfortunately, the concrete industry is stuck calling what really is "dehydration" of concrete, hydration.

It will help. If you are not interested in ever doing a coating, go for a densifier with an added waterproofing agent. Better for the spills than a standard densifier.
