Re: drylocking a basement
This is why you NEVER go to a big box with questions, Evil Orange seems to be the worst in this regard.
1 - Read the label of the product, most of the time there will be detailed prep, use, clean-up, and disposal instructions.
2 - Go to the manufacturer's website, most have the same, if not more, detailed info about their products.
3 - DIY forums and public access professional forums such as TOH are good places for first hand experience from both the layman and the professionals who have used these products.
The key to any paint job is surface prep. As MLB points out, it is important to get the surfaces clean and dry. Loose, chipping paint has to be removed, you don't have to get rid of every spec, but the loose stuff definitely has to go. I would also recommend not buying product until you're ready for it, then have the store shake the can for you so that it is freshly mixed for use. Mechanical agitation is far better than anything you'll get with a manual paint stick. Again, following the label, use the correct brushes and rollers for the application.
