I have a few questions about Boysen Cool Shades. Do you recommend it for a flat concrete roof and exterior concrete walls? And is white the most effective for cooling?

Hi as well, Boysen User S.
Thanks for asking about Boysen Cool Shades!
I know it sounds great to have the paint’s cooling effect not just on your roof but on your walls too. Your whole house would be reflecting heat from all sides! But no, it can’t do this. Boysen Cool Shades is formulated for use on roofs only.
Boysen Cool Shades can be applied on surfaces such as galvanized metal roofs (yero), aluminum, stainless steel, and unglazed roof tiles. It cannot be used for your flat concrete roof. I’m assuming it’s a roof deck? You can’t use Boysen Cool Shades for it, unfortunately.
To answer your second question, yes, you are correct. If you want the best heat-reflecting color which will then be the most effective in terms of helping cool down your home, go for the color Reflecting White. Though, not very useful info for your current situation, it’s a good tip to keep in mind if you do need to paint a metal roof in the future.
Instead, if you would like to paint your roof deck, I recommend Boysen Acqua Epoxy. It’s an exceptionally durable paint that can be used on concrete floors.
Boysen Acqua Epoxy solvent-, chemical-, and stain-resistant. It has good gloss retention and UV resistance as well. Because it’s water-based, it’s also easier to work with than solvent-based paint products. Want to waterproof it first? Find a guide for waterproofing roof decks with Plexibond here.
Hope I’ve been helpful even if you can’t use Cool Shades on your roof deck and walls. Good luck!
