Prosoco R-Guard Fast Flash

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.

Applied product to pored concrete wall and sill plate. 1 1/2 inches on each to seal the sill plate and stop bug and air/water infiltration. Went on smoothly. Glad i saw this on the Build channel.

Pretty easy to tool even in cold temps, initial tack very good, sag resistant but self levels a bit (I probably used it where I shouldve used the joint filler in some cases.) Is just nice to work with...when paper towels are readily available to keep the spreading tool and all of ones clothing clean. I cant review the properties I cant test such as breathability etc but itd have to be far better in that regard than the off the shelf caulk type products.

We really like this product

Product was fully expired when received. Only out a week. I used it anyway as it went on a personal project but would never have installed it on a job. It is excellent product though!

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

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

Great product! Good value

Exploded in my $50 gun. What a mess.

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