Most people understand that waterproofing masonry is a good idea. The video below is quite amateurish (I shot it from my phone, narrated it on the fly, and it has some choppy splicing…), but is fundamentally educational.
Any masonry that can be penetrated by water can be affected by freezing temperatures. Rocks are broken down by moss, lichen, and frost wedging. This happens to masonry as well. As a matter of fact, the reason that you are able to eat a salad is that rocks were broken down into soil because of frost wedging (and other factors) breaking down rocks.
Masonry to consider waterproofing
- Walkway and driveway pavers
- Any brickwork exposed to the elements.
- Stonework ( repairing mortar joints on stonework is particularly time-consuming and expensive.)
- Cinderblock walls.
Precautions for waterproofing
- Some waterproofing agents can etch glass, therefore windows need to be protected against overspray.
- There are parameters for applying waterproofing agents, such as temperatures during and after application, and starting out with a dry surface in the first place.
- If a masonry surface has been painted, the best bet is (usually) to make any repairs, prepare any painted surfaces and paint the surface again. We use Sherwin Williams Super Paint or Masonry paint exclusively.
- Super Paint can be applied at 50 degrees temperatures and up. It will dry in about 3 hours at 50 degrees per our experience.
- Any masonry repairs done with mortar, etc., need to cure for 30 days PRIOR to painting or waterproofing.
- Waterproofing is not to be applied during heavy winds.
