Anyone use a sprayer to apply sealer?
- Thread starter woohoo

I don't think there is any advantage to using a sprayer. The sealer I used and others I have seen are only a little bit thicker then water. I think its more important to keep a wet edge as you apply individual coats. I have heard of people using a garden sprayer to get it all down quickly. You want the sealer to stay liquid as long as possible so it will penetrate the surface of the concrete. It seems that with spraying you would get less sealer down and it would dry much quicker then with rolling.

No one can answer this question effectively without knowing what kind of sealer you are thinking about.

Go by the sealer manufacturer's instructions. If you plan on using a Wagner sprayer, see if you can apply multiple coats. One coat out of that kind of sprayer will be thin and inconsistent at best. It may help to backroll it after spraying too.
It depends on the sealer, but most can be applied with a pump-type sprayer. I've never seen a sealer that suggests using a power sprayer, and I'd guess that a power sprayer may apply it too thick. Sealers are best applied in thin coats; thick coats are more likely to flake and peel.

There are TONS of concrete sealers that suggest using an airless sprayer, like our BondTite 1101.
Our AcryliSeal 3401 is a more standard solventborne sealer that can be applied by airless (for large areas), pump sprayers, or just dip and roll.
The point is, we have about 30 more sealers for concrete that all can be applied by various means and thicknesses... and... we are just one company. How many coats you will need depends on the porosity of the concrete. Our BondTite 1101 can typically be applied in just one coat... thick if you want to. Conventional solventbased products (like our AcryliSeal 3401) should be applied in thin coats as rt66jt mentioned. The same thing applies to waterbased products. Those types of products contain solvents or water that must evaporate for the film to form with any amount of integrity. Applying these too thick can 'trap' solvent in the film and weaken the coating to make it more subjective to peeling and chipping. Trapped solvent and water can also promote yellowing and film porosity (which defeats the purpose).
Anyway, most of these responses are given based on the perception that you are using a certain type of sealer by the poster. As I read them, I can tell what type of sealer the poster has in mind that you may use. And, their advice for that type of sealer would be good. However, there are SO many options these days and I want to stress... application depends on the exact sealer you choose... PERIOD!
