Sticks to everything, GREAT

a year ago
(This review was collected as part of a promotion.) It flows very smoothly out of the tube when using the caulking gun. I cut the tube tip on an angle as instructed (always read the instructions on the product). My test...Water just beads off the clear caulking after washing the siding. It is still stuck to the siding. Great for windows, doors, siding, holes, eavestroughs.

Use outdoors as indicated!

a year ago
(This review was collected as part of a promotion.) We used the Mulco Flextra in the clear option to help seal up our exterior doors and the framing around the garage door also. This product is extremely fast drying which was great so we could move on to our next project. The smell is very overpowering I found though, so definitely use outside as directed on the label!

Easy to use!

a year ago
(This review was collected as part of a promotion.) as a homeowner, it’s important to make sure that everything is nice and sealed for when winter approaches. getting the Mulco Flextra Clear complementary for review was a great reminder for me to make sure that my windows are ready for all the rain that’s coming. It was super easy to use and definitely feels secure.

Does the job

a year ago
(This review was collected as part of a promotion.) This was given to me in exchange for my honest review. I received this just on time as I had some dryer vents outside that needed replacing. Upon purchasing our new vents, we used this to seal the sides. It comes out super easy, and is easy to apply. It’s a great quality sealant and I would definitely recommend it.

Works Great

(This review was collected as part of a promotion.) I was selected to try the Mulco Flextra Clear Sealent for doors, windows and siding and found it very straightforwardand easy to apply. I foind this sealent worked as described. I used it on one of my outside windows and had no issues with applying it. I liked that this is clear and can be painted once it dries.

It's okay.

a year ago
(This review was collected as part of a promotion.) I'm a beginner at most home DIYs but I have previously used caulk so I thought I'd be okay with this. I had a hard time with the flow, and it has a very strong odour. I used it to seal around a basement window, and while it did help, I'm not sure I would pick this particular type of caulk for the job next time.

Seals and works great!

a year ago
(This review was collected as part of a promotion.) We used this sealant on a few different projects we had to complete. It was perfect for around windows, siding and our brick work. It dried super fast and was exactly what we expected from a good sealant. I love that its multi purpose so we can purchase one tube for all our projects! That is a huge benefit.

Great product!!

a year ago
(This review was collected as part of a promotion.) When we recieved this to try we were very excited to fix up a few spots on some windows with moisture problems. The texture is just right that it can be applied easily, its totally clear which is the best and it does its job perfectly. Weve had no problems around the windows since so we are very happy!!

Great product!

a year ago
(This review was collected as part of a promotion.) After trying this product I can say that it is quite easy to use/apply, and it’s definitely a plus that it dries clear. I would say that it does have a lingering smell which is why I gave this a 4 stars but after approximately 7-8 hours the smell went away. Great for quick fixes, and DIY projects!

Easy to apply, seems durable

a year ago
(This review was collected as part of a promotion.) My house is quite old so some of the windows need sealing. After cleaning the area well, I applied Mulco to the exterior. I’m mostly worried about ants and other insects coming in and making nests as well as humidity seeping through. I’ve applied it a few weeks ago and so far it’s held up well.

Mulco Flextra clear

a year ago
(This review was collected as part of a promotion.) Mulco's Flexstra Clear sealant is easy to use and did a great stopping drafts along my door. I received this sealant product for free from Influencer for my honest opinion. I would recommend this product to anyone as it’s easy to use and the clear colour would and could work in most places.

Works as advertised

a year ago
(This review was collected as part of a promotion.) It’s hard to get excited over sealant, but here goes nothing. We have a few older windows that needed a bit of extra sealing to prevent drafts. This did the trick. I don’t have much experience with other brands or even with many sealants in general, so it’s hard to say where this stacks up.

Super Easy to Use for a Novice!

a year ago
(This review was collected as part of a promotion.) I am so happy I got to try out Mulco Flextra clear sealant free thanks to Influenster. It was super easy to use and I used it to seal around the outside of my windows. It was super easy to apply and in less than 24 hours it was complete. Can't wait to try it on my doors and siding.

(This review was collected as part of a promotion.) I used Mulco Flextra Clear to help seal the outside of my home. Small areas that eventually need repair, and it worked perfectly! The smell was not as bad as other sealants which was a nice surprise! Overall a good product, I would recommend it for future home projects for sure!

Does the job!

(This review was collected as part of a promotion.) This was my first time trying this brand. It was nice and thick yet easy to apply. It dries very quickly, so make sure you are prepared with whatever materials you need of you want to remove excess. My only complaint would be that it smells quite bad, it has a very strong odor.

Mulco is great!

a year ago
(This review was collected as part of a promotion.) Mulco Flextra Clear worked really well for my windows. We used it for our bedroom windows as it needed better sealing. We noticed a difference in the rooms in terms of a little less of a draft coming through the window. Looking forward to testing it out better for the winter!

Run of the mill sealant

a year ago
(This review was collected as part of a promotion.) This product doesn’t really stand apart from other sealants I have used. I would say it has a stronger smell than other brands, but as far as effectiveness and user-friendliness, it’s pretty basic. It has, so far, held up well and I would say it’s definitely beginner-friendly.

Must haves for home owners

a year ago
(This review was collected as part of a promotion.) Since buying my own house, I noticed small gappings in for instance my office from the floor board. Mice sometimes would come out of there. This product has saved me! It’s not only clear, so it doesn’t look ugly. But also. so efficient so mice or other pests can’t get through.

Worked to repair my pot!

(This review was collected as part of a promotion.) I receieved the Mulco Flextra Clear from Influenster to test, and it did not disappoint! I didn't have a bathroom DIY to try, so I used it to reseal my cracked planter, and it worked beautifully! You can't see the crack and it has stood up to a week of watering already!

Easy to use

a year ago
(This review was collected as part of a promotion.) We got this voxbox exactly when we needed it! We had a wicked storm and needed to buy some caulking to replace our vent grate. It was easy to apply and dried pretty quickly. Definitely would recommend this to friends and family. It didn’t bubble or dry up while applying.

Straight forward

a year ago
(This review was collected as part of a promotion.) We received this in to use in exchange for a review and honestly it was pretty straightforward. The application was pretty simple and went on well, cleaned up around the area nicely as well. It isn’t anything special but having used this before I’ll probably use it again

Facile à utiliser et invisible

a year ago
[Cet avis a été recueilli dans le cadre d’une promotion.] Le Mulco Flextra Clear est très facile d’utilisation. C’est un produit pour les travaux extérieur, mais j’ai quand même trouvé que l’odeur était forte. Nous l’avons essayé sur le gazebo et balcon pour quelques corrections et le produit fini est impeccable pour le moment.

Worked Like A Charm!

(This review was collected as part of a promotion.) The Mulco Flexutra Clear Sealant made redoing my windows a piece of cake! All I needed was a mask and a caulking gun and I was ready to go! It dried evenly and within 24hrs I was able to paint it to match the trim! Great product and perfect for all levels of experience!

Product worked well and seal is A+

a year ago
(This review was collected as part of a promotion.) First time using this brand of product. Install was the same as all caulks but the ease of product was impressive. Came out smooth, easy to wipe clean and created a nice clean seal. I will be looking into more of this brand of caulk for future projects around the house

Works as expected

a year ago
(This review was collected as part of a promotion.) I received this product from Influenster and used it to re-seal seal my bathroom window. It went on easy as expected and I was able to edge it perfectly afterwards. The smell was a bit strong inside the house so I ran the bathroom fan for a few hours after application.

Good sealent

a year ago
(This review was collected as part of a promotion.) Pretty good sealant! Used around our bathroom vanity to seal it against the wall. Not a strong smell from it either which was nice! Dried very quickly and was very easy and seamless to apply. We do have a gun for the type of tube that it comes in, and that is a must.

Great sealant for door

a year ago
(This review was collected as part of a promotion.) Our door was looking a bit drab and needed new sealant. The Mulco sealant came to the rescue. It is thick but went on clear. The door/window looks great now. One thing to note is that it is quite thick and because of this wasn’t as easy to apply as interior calking.

Easy to Use

a year ago
(This review was collected as part of a promotion.) I watched a few videos on how to apply this so it’s not all clumpy and messy. I used this around the bottom of mine of my windows that had a draft. It was easy to use, dried pretty quickly. I like using the clear sealant as I find it’s more forgiving than the white.
