Self-Leveling Lap Sealant 1/2/4/6/8/12/24 Pack - 30s Shield for Windows, Vents & Crack Repair

As an RV Tech this is my go to!!

Easy to work with

Self leveling calk is good stuff as is the regular mastic. Each type has a job😁

If you're dealing with stubborn roof leaks (especially around vents,skylights,or flashings),don't waste money on cheap sealants anymore. Kohree is a professional-grade product that will give you peace of mind and ensure a perfect job. This stuff is incredibly sticky! It took me about 40 minutes to re-seal all the lifted shingles. This stuff really works. I used it like a contact adhesive. Apply to the surface,press,peel back a little,then use your body weight to press it down firmly for a solid bond. This stuff is super sticky!

Black is not easy to find. Works great for re-sealing the exterior seams on camper trailers. Adhesion is excellent. So far,so good,we'll see how long it lasts.

I bought this black roof sealant,and it finally solved the stubborn,slow leaking problem around the chimney flashing. Its self-leveling properties are excellent,requiring minimal finishing to perfectly fill the tiny gaps around the flashing. It adheres immediately to any material - metal,asphalt shingles,and brick. Highly recommended for all serious DIYers and professionals!

My EPDM roof was leaking,and this sealant stopped the leak. I installed it on the roof of my house in Miami,Florida. I inspected the seal yesterday,and it is still very pliable with no cracks whatsoever.

We had to use it on our camper. Great flow and sealing properties,didn't leak even after heavy storms and high winds. This is a hard result to achieve. This is the best new product I've discovered this year.

Used it on the seals for my camper's wood stove,and it worked great - I even installed it in the rain,and it still sealed perfectly! For any future sealing work,I'll definitely use this again!

It performs excellently in waterproofing and roof repair. The results are very good. I will buy it again. Excellent sealability. Easy to apply.

Works great for EPDM roof seams. Excellent bonding. Good quality product,fast service and shipping as well!

I used it with reinforcing mesh on the seams of a metal roof,and so far no leaks. Easy to use,just follow the instructions. Highly recommend!!

I installed a new black sink in my kitchen,and the black sealant matched perfectly. It has great adhesion,dries quickly,and is easy to clean.

I've tried other sealants,but none worked. Only this gray sealant was able to successfully seal the hard-to-find leak spots in the metal roof seams in the harsh Vermont environment. Its consistency is very pliable,making it easy to apply and smooth out as desired. I'm so glad I chose this among the many similar products.

I used it to fill the eaves gutters and chimney,no leaks,I'll continue using it,thanks!

Looks like a nice product. It completely met my expectations. Thank you,please keep it up!

I used this in my shower. Had a few small leaks,and it sealed them right up! This product is amazing!

I used it around the eaves gutters,and the color match is perfect. No issues. Product matches the description.

I brushed the edges and then rolled the surface. It took over 2 hours. I applied it thickly,and used 3 gallons on a 40-foot fifth-wheel trailer,wish I had bought an extra gallon,but I'll re-coat it in the summer. I got the gray color to ensure full coverage. I recommend this product because it looks rugged. It's also very easy to apply,and the finish is great once dry. I'm glad I found the gray version!

This product works very well. My father found a small leak spot on the roof,where a nail wasn't seated properly,and this sealant stopped the leak.

I've been using this product for years. It works great and has excellent bonding strength. I used the black one to re-seal a few new roof shingles on my house. Since it's black,I just applied it under the shingles. Its durability has far exceeded my expectations.

I used it to seal the gaps between window frames and sills. It works great,is virtually invisible,and is easy to apply. Dries quickly too. Affordable and convenient.

I love this product,it's exactly what I needed,very convenient to use,as my canvas's vinyl material was cracking and drying out,so I applied two coats,and the results are amazing! The gray color matches great,significantly improved the waterproofing,and greatly extended the vinyl's lifespan! Just washed it a few days ago,and it looks just as good as when I first applied it.

We used it on our balcony floor and wooden railings (after filling some rotted holes in the wood),and so far it's holding up great. The color match is perfect. It's easy to apply,and the finish looks great once dried. I'm glad I found the black version!

Bought 2 gray ones,no leaks so far,curious to see how long it lasts

I've struggled for a long time to get roof patches to seal properly. Finally found this product,and it's great - excellent sealability and super sticky! No more leaks in my roof,thank you!

This stuff looks a lot like roofing asphalt,so I ordered it. This is exactly what I wanted. I was enclosing a trailer and needed a sealing material. It works great. Can use it anywhere a strong seal is required. Slightly pricey,but definitely durable.

It's very user-friendly,just need to wear disposable or rubber gloves when using to avoid making a mess.

I DIY-ed my roof repair and saved over $1,000. I think it was a worthwhile investment. I will definitely use it again. Highly recommended!

I used it on our rubber roof. Easy to apply,and even better when heated in the sun,perfect!
