Prosoco R-Guard Fast Flash

Great product! Good value

Pay attention to the date of manufacture, it has a shelf life of 12 months. Like others mentioned, product arrived 3 months out of date and didnt properly cure. This is a basic silyl modified polymer, there are lots of other better products out there. I ended up going with 3M Adhesive Sealant 740 UV, which was half the price and a much better product.

I became aware of this product from the You Tube channel , The build Show , Matt Risinger. When the flashing membrane I was using for my new window came loose , which I would never known if it hadnt been for the fact that I was running behind on my project, I ordered R-Guard. It was a bit tricky getting it in all the places being this was for an upgrade to a larger window. What an awesome product. I purposely did not close the brick veneer up on my window to make sure it would work. Results are awesome.

A great fluid applied flashing, works with a sausage gun. Working time of the flashing was as described, and it bonds very well.

Learned about it in the Build Show. Works really well, easy to use.

Great stuff, easy to use and does exactly what it’s supposed to. Make sure you’ve got a sausage gun. Won’t work in a regular caulking gun.

Wow!! Just wow!! Great stuff that holds up well to all the excitement!! one tube goes a long ways if you use it properly!!

A little expensive at this price, but the product is great. Id use it anywhere I can.

We really like this product

Works, but a little spendy. Need to sell a 2, 3, 4 pack for cheaper or something
