Low Odor quick dry sealant
(This review was collected as part of a promotion.) Great product for sealing your door and window trim before the cooler weather sets in. We even used it on our chicken coop to seal cracks so they stay warm this winter! We could rest easy knowing it was odorless too. It was very easy to apply, just cut the tip and get started. We found it hard to get it started because of its density but once we got it started it was smooth. I might suggest plastic tube instead of cardboard as our tube started to collapse a bit at first. The super quick drying time was an added bonus althought we needed to work quickly to make sure it was where we needed it to be.

Can't use indoors!
(This review was collected as part of a promotion.) I was really excited to get this voxbox from influenster because I had lots of indoor spots that needed to be repaired. However, upon looking at the instructions, it says in big bold letters "DO NOT USE INDOORS". Unfortunately I wasn't able to use it right away and we have recently moved. My new home could use this on a couple of spots, but my moving truck has yet to arrive. I gave 3 stars based on the size of the bottle and other customer reviews. It lost a star because of how it's only for outside. I'd rather have 1 product that I can use inside and outside instead of seperate tubes

Pliable and cleans up nicely!
(This review was collected as part of a promotion.) We received this product for free from Influenster to test and review. My husband decided to test it out in two areas - to seal an exterior crack that is causing a leak when there’s a downpour and the rain hits the house just right, and to re-affix our furnace stack topper that blew off in a recent windstorm.
As many have indicated - it stinks! However, after using this sealant the first thing my husband said was
“Oh ya, I like that sh*t!” He claims the best feature of it, is that it doesn’t stick to your finger - it’s like a gel and it’s pliable. He is very impressed by this and plans to switch to this brand going forward.

It did the job!
(This review was collected as part of a promotion.) I used this on new windows that were installed in my home recently that werent caulked properly by the installers. During the winter months I get frost inside the windows due to that and during the summer the humidity. Since applying this product the humidity levels on my thermostat have come down dramatically from 63% to about 45%..it was quick and easy to apply. It came out of the tube easily and cleanly. So far it's done a far better job than what wasnt there to begin with. I can absolutely see the difference as a result. My home is definitely much less humid. Now to see if it can withstand the same test during the winter months!

Works great! Easy and pain free use!
(This review was collected as part of a promotion.) This product is a go to for any sealing needs! It is very easy to use, smooth application, dries quickly and is actually clear as advertised! There is no awful smell to the product or sticky, messy application! I am usually a do it yourself type of person and this is definitely a product I could use without needing a lot of instructions and demos! Used it along the outer windows/patio doors to stop a small draft from getting in and the problem was solved quickly and easily! I would definitely use this product again as well as recommend it to others! Thank you Influenster for sending me this product complimentary for my honest review!

Easy to use, seals clear
(This review was collected as part of a promotion.) We found it very easy to use and the results looked great. Came out of the tube smooth for easy application. We recently moved into a new house and the back doors and side door were not properly sealed as wind and light comes through them and also a laundry vent was poorly done. We used the Mulco Flextra around the trim, door and vent to seal them. It works perfectly. The clear was a nice change from white, you can’t hardly even see it. Great energy saver! And it’ holding strong. We’ve had some high winds and rainy weather so far. Will be great for the winter if we can’t get the doors fixed before then! I would use this product again.

Great calking - near invisible.
(This review was collected as part of a promotion.) Great caulking. Came out of the tube smooth - easy application. Used it to seal screen porch from insects. Sealed great and was almost invisible when it dried - not at all cloudy. The only issue I had was that the nozzle was about 1/2” too long. When I used the seal puncture pin, the nozzle was too long (I cut the tip so I could have a small diagonal cut for my application) so I had to use something else to puncture the seal. Nothing crazy, just an inconvenience that I’d never run into before. Other than that, was a great product. Would recommend.

Scellant extérieur Flextra
[Cet avis a été recueilli dans le cadre d’une promotion.] J’ai reçu via une campagne rémunérée un tube de scellant haute technologie thermoplastique Flextra de couleur claire , à utiliser pour les taches extérieur. Vous pouvez l’utiliser pour les portes, fenêtres et parements. Dans mon cas, je l’ai utilisé pour les fenêtres de mon véhicule récréatif. Relativement facile d’utilisation, j’ai été extrêmement satisfaite du résultat final! J’ai aussi reçu des commentaires sur ce produit disant qu’il était extrêmement durable sur le long terme. Je continuerai d’utiliser ce produit sans aucune hésitation.
