Applied easy

Needed badly

[This review was collected as part of a promotion.] I applied the Titebond Radon Sealant on all my exterior door frames and entryway to my crawl space under the floor. The sealant applied very easy and upon drying it was very durable. After a 2 day rainstorm, I found the sealant held up well against high winds and heavy rain downpour. I successfully filled cracks and missing door frame seals with ease. It is a very useful, competent and functional product. In my home exterior entryway, I have Mexican tile that had cracks and is missing grout. I applied the sealant and it dried very durably and after two days of walking on these tiles, the sealant held up very well. Overall, applying the sealant is fairly simple yet you should plan to have drop cloths adjacent to the areas being sealed as it will ensure you won’t soil adjacent tiles. It makes clean-up simple and easy. It is important to clean the applicator after each use to maintain its optimal performance and preventing clogs and uneven applications. This is an excellent product that will deliver performance you expect to mitigate radon and address cracking and missing grout. The sealant will serve you well and I give this product a 5-STAR Rating.

awesome stuff. highly recommended.

It was easy to use and it appears from our radon meter it has successfully lowered our radon levels to within normal limits. We already have a radon exhaust system, but the numbers were starting to go up again to unhealthy levels.

worked great sealed small area where water and radon could enter by crack between floor and wall. Get a battery radon tester you can use around the house vs a one use test by a lab if any concerns

[This review was collected as part of a promotion.] This titebond radon sealant is easy to apply. My policy with caulk is to cut the tip small so it is easier to control the area you are trying to fill. This product does dry very quickly so definitely wipe and excess off immediately. The sealant does say that it is VOC compliant but it does still have a very small odor.

I chose this based off a Radon YouTuber who said this is what the pros use. Idk how the pros can use it because it will require you to come back everyday and add another layer. I have a brand new house with seams between the 4 concrete pads. Every time I would add this it would just get sucked down and disappear from being level with the concrete. I eventually had to shut off my radon fan and then apply about 3 coats before I started seeing it sink down and also bubbles penetrating it. I went from buying 3 tubes, to needing over 12. In my opinion, I think you'd be better off just buying standard concrete caulk that would harden and isn't so soft and calling it a day.

So, I did not receive product even thought status showed it would be delivered 2 different times. Called Walmart, they said they couldnt check shipping.......customer srvs cant chk shipping? Thats a new one, as I used to be a director of fulfillment, I know better. CSR said, "For your troubles, I will refund you, but it might still show up." For your troubles? Now, it appears as though he cancelled it, due to being lost. UGHHH!@%23$%^%26

Item delivered to wrong address, despite editing it (several times) on the Walmart website before purchasing it. Called customer service explaining that I could not pick up the package at the indicated address as I no longer reside there and spoke with “Clueless” who stated that it was too late to do anything as item was already out for delivery. ( in this electronic age of email and texts and even good old cellphone). “Clueless “ suggested that I contact my credit card company and dispute the transaction. Strange response. Good Bye Walmart.
