Product Description

By entering your model number, you can make sure that this fits.
New construction and retrofits should have waterproof rough openings. It eliminates the need for reinforcing tapes at sheathing joints, inside and outside corners, which cuts down on surface preparation time significantly.
FastFlash adheres to damp or dry surfaces and cures in a wide range of weather conditions, making it suitable for all climates. It bonds and cures in wet weather and on wet substrates, and it can withstand rain right after application.
It's simple to apply with a gun, spread-and-tool, or roller to create a long-lasting, seamless elastomeric flashing membrane.
No solvents are used. There are no isocyanates in this product. Free of phthalates. The ASTM E84 Standard Test Method for Surface Burning Characteristics of Building Materials was successfully completed. LEED, Living Building Challenge, Cal Green, and ICC-ES Ready certifications are all available.

Questions & Answers

I only need to coat one sheet of ply. rather than spending $600 on a 5 gallon pail of cat5 - Is it possible to use fastflash across the entire sheet?

Hello, I don't think there's any reason why it shouldn't be possible. This is fantastic. It's just a matter of putting in more effort to spread it over a larger area. Yes, Cat5 is costly, but only a small amount is required. I'm not sure how many fast flash tubes you'd need to cover a ply sheet. It's only been used to fill in the gaps between the plywood sheets. Best of luck!

Is it possible to paint over this material?

After it has been cured, this product can be painted. It usually takes around 2 hours.

Is this product UV stable, and if so, how long will it last?

According to the information sheet: For a period of up to 12 months, this product can be fully exposed to UV and weather. If it's been more than a week, make an appointment for an inspection.

Is it flammable in any way?

This product should not be used as a fire-retardant caulk.

Selected User Reviews For Prosoco R-Guard Fast Flash

Instead of 3M Adhesive Sealant 740 UV, which is out of date and overpriced, use 3M Adhesive Sealant 740 UV
3/5

Keep an eye on the date of manufacture; it has a 12-month shelf life. As others have stated, the product arrived three months past its expiration date and did not cure properly. This is a basic silyl modified polymer; there are many better options available. I ultimately decided on 3M Adhesive Sealant 740 UV, which was half the price and a far superior product.

The Best
5/5

I learned about this product from Matt Risinger's YouTube channel, The Build Show. I ordered R-Flashing when the flashing membrane I was using for my new window came loose, which I would never have known if I hadn't been behind on my project. Because this was for an upgrade to a larger window, it was a little tricky getting it in all the right places. What a fantastic product; I purposefully left the brick veneer on my window open to ensure that it would work. The end result is fantastic.

Sealing from the sill plate to the concrete! The product was applied to a porous concrete wall and a sill plate
5/5

1 1/2 inches on each side to seal the sill plate and keep bugs and water out. It all went well. I'm glad I stumbled across this on the Build channel.

This is something you'll grow to appreciate
5/5

You will initially despise this product because it will feel messy and you will use far too much of it, causing you to believe it is excessively expensive; however, after a few windows, you will notice that it is much cleaner. The way it seals out air is my favorite part. There is no draft at all after the windows are installed, and this is before the window is foamed. Not to mention the fact that I am confident that my windows will never leak. Yes, it's pricey, but the flashing tapes aren't cheap either, and they're a pain to use. They're also far from perfect, especially if your openings aren't perfect or brand new. You can use this to coat a cardboard box before filling it with water. It is not going to leak. The box will not leak even if you put a screw through it. This is documented in a YouTube video. I can now do a 36x60 window that had a lot of jams when I was doing it at 8. 5 inches. This was done both inside and outside around insulation lockouts, and only one tube was used for this one window. You'd use a lot less if you were just doing a regular window with regular jams. If you use more than that, you're overdoing it. It spreads in all directions, but it doesn't feel like it will, so it's easy to overuse. The other product, which is a joint and seem filler, is also fantastic. I'm a homeowner who is installing my own windows and was looking for the best product available. I also don't think foam alone will stop air drafts as well as other windows I've had that leak air like a siv around the interior casing and required caulking. There was no such issue with this product prior to the foam.

Keep an eye on the date to see if it's about to expire
3/5

When I received the product, it had already passed its expiration date. It was only a week that she was gone. I used it anyway for a personal project, but I would never use it on a job. br>br>However, it's a fantastic product!.

So far, everything has been fantastic
5/5

It's fairly easy to tool, even in cold temperatures, has good initial tack, is sag resistant, but self-levels a little (I probably used it where the joint filler should've been used in some cases). ) Is simply a pleasure to collaborate with. when paper towels are readily available to clean the spreading tool and one's entire outfit I can't comment on properties I can't test, like breathability, but it would have to be far superior to off-the-shelf caulk-type products in that regard.

Water and air seals around windows and doors are made with this fantastic product
5/5

This is a product that I frequently use and enjoy. It takes a little practice to figure out how to use it properly, and it takes longer to use than sticky tapes, but I believe the quality is far superior. br>br>I wish they had more options when ordering on Amazon, such as quantity amounts to reduce shipping costs. Ordering in 5 increments, for example, is a good way to go.

This is next-generation technology, but it's more expensive, and it works incredibly well
5/5

This is unquestionably Next-Generation technology. However, it is significantly more expensive than using plastic or tarpaper, and it requires 24 hours of setup time before you can install the window, requiring an additional day. If you complete the entire system (which is a two-part process), you will receive a certificate. If you repeat the process, you'll need an extra two days. Purchase small spreaders and wear gloves because the stuff tends to get all over the place.
