Can this material be used on the outside face of existing stucco knowing that we are going to install a metal rain screen system to protect the stucco from wind and rain?
1 Answer
CrownSeal can be used wherever a long-lasting exterior waterproof membrane is needed, such as chimney crowns, chimney corbels, the tops of masonry walls, including parapets, and stucco repair.

Nice Product
The CrownSeal Premixed Flexible Waterproof Coating was easy to apply with a trowel and then smooth with a paint brush as the instructions stated. It is important to have the right weather conditions - both temperature and no rain in the immediate forecast. Inclement weather was in our forecast and got to Chicago before the product set up and cured. As a result I'll have to reapply in the Spring.

Came quick
Went on as described. So far no leaks and no moisture.
It didn't smooth out as well as I hoped.
It took longer then 24 hours to cure. It needed more time but could be from the cold weather that moved in.

Easy to use, Great product
The material goes on smoothly. It was my first time using it. Using a stiff paint (or masonry) brush with water does wonders to give you a nice smooth surface removing any trowel marks.
Easy to use.
Takes 3 days to dry/cure. Make sure you have several days of sunny cool weather.

Professional Grade
This is the same product the chimney company used next door. Good stuff. Work fast or set a shade over it if sunny. Gets harder to work with once a film starts to develop.
Good quality. Premixed saves a lot of hassle and guesswork.
