Best way to apply DryLock

What’s the best way to apply DryLock?
How many coats of DryLock should I do?
How long does DryLock paint last?
Is DryLock waterproof?

Using “The Crawford Technique” you will save a lot of time, save a lot of money, and also do a perfect DryLock job every time with no prior experience.

Let me know if you have any questions.

I've been painting for decades and learned this trick myself. It really does work and beats using a brush

Get a paintbrush Ash.

More seriously. I have a rain exposed wall (ground + top floor). There’s already an old coat of paint on it. Do i scrape that off with a “i don’t know what tool” and then apply the DryLock white paint?

The light in the window makes me think those walls are above ground- if that's the case not sure why waterproofing would be required.

Interesting. It makes me think a paintbrush would be better in this case, as you're essentially sliding over the surface rather than rolling. The whole point of a roller is to do a quicker job (it's certainly not to save on paint - I can tell you!)

Is drylok still effective even if there’s paint on concrete
