Great Stuff 99112809 Smart Dispenser Pestblock, Gray

Really happy with this product overall. It works exactly as expected, feels well made, and has been very reliable so far. Great value for the price and I would definitely recommend it to others

Update 12/1/2024: Previously using the foam applicator tube had been challenging and messy. Yet, I don't appear to be smart enough to operate the new "Smart Dispenser" tip. I simply can't get the Smart Dispenser tips to work properly or sometimes at all. I'll try another brand with the old tip style. Living in a rural setting means taking a hands-on approach to keep unwanted critters at bay. My proximity to neighbors with cattle and chickens, along with my encounters with various small wildlife, necessitates a strong defense against potential intruders. Fifteen years ago, I discovered a method that has proven effective: installing copper mesh secured with Great Stuff 99112809 Smart Dispenser Pestblock foam under the bottom edges of my home's James Hardy cement siding. This combination has successfully prevented entry from various pests. The Pestblock foam is particularly noteworthy for its durability and pest-deterring capabilities. However, application can be messy and requires careful preparation. I learned the hard way that protective gear such as gloves, long sleeves, and pants are non-negotiable, as the foam adheres to skin stubbornly, leading to an uncomfortable removal process. I'm currently applying the same technique to seal the bottom openings of a steel shop building, aiming to deter mice without creating an entirely impenetrable barrier. Despite the application challenges, Great Stuff Pestblock remains my go-to solution for effective pest control in a rural setting. Its performance outweighs the cleanup inconvenience, making it a valuable tool in maintaining a pest-free environment.

Works as intended. Expands a LOT. Beware that it does not stay gray! This is about a week after application. Not in dorect sunlight, it is a deep cream color.

It really works just don't push too much material in the grooves, simple push, try it yourself first.. Headache Freeeeee It seals the grooves with roach killing foam that freezes in place.

I had a water softener removed from the garage and it lsft big holes in the wall. This stuff really works perfectly and is easy to apply. It dries as predicted and stuck perfectly to the wall where the pipes were. I think it will keep out the critters too Now to cut them, sand them and paint. Easy peasy

The foam does expand and covers what you need when applying to surfaces. Adheres to the surfaces The problem is that the sprayer doesn't always work well. Foam starts grey but yellows after it dries.

This is great for filling cracks or holes around the house so bugs and critters don’t get in.

Than that of the manufacturer, Dupont. First, the spray handle never tightens: it spins around like a top. This crap is a mess.. I ruined a pair of gloves cleaning up the drips that this product doesn't produce. There is no foam per se. I thought it would come out like the foam you see in the picture that's orange. That's what I get for thinking. The product dries white, not grey. I'll spray paint the area but I shouldn't have to do that. This is like cake icing and it drips all over. Never, never, never again. Dupont, you got my $ once; I hope you spent it on something that wasn't frivolous because it's the last you'll get from me. There is zero quality, application is nearly impossible, for lack of a better word. I wisj I could mail this crAp as is back to Dupont and then maybe they can tell us all about the versatility of shoving it up something else that is more apropos. The ad says the item can be returned but that's a lie. I hate that. If an item can't be returned, why have a return policy?
