## Description

Liquid Rubber Waterproof Sealant is an environmentally friendly coating that is easily brushed on and cures into a waterproof membrane. It can be used in many applications where you need to create a watertight seal. Flat Roofs, Metal Roofs, Sloped Roofs, Planter Boxes, Foundations, Sheds, Basements, Metal, Wood, Concrete and more. Use Liquid Rubber Seam Tape or Liquid Rubber Geo-Textile to bridge seams, joints, vents, protrusions to create a long lasting repair or rejuvenation. Apply when temperature is above 10C/50F including overnight temperatures. Apply to a dry surface, free of dirt, loose flaky paint and coatings, oil, grease, coal tar or other contaminants including laitance and efflorescense. Typically cures within 24-48 hrs. Do not freeze. Store in a warm area. Do not apply in wet conditions or if rain is forcasted within 24 hrs. Not meant as a constant walking surface. Coverage - Vertical Surfaces - Apply a minimum final thickness of 1 gallon/30 sq ft (2.8 sq m). It should require around 3-4 heavy coats to achieve a 30 mil (0.76mm) (DFT) membrane. Flat/Ponding Surface - Apply a minimum final thickness of 1 gallon/15 sq ft (1.4 sq m). It should require around 4-5 heavy coats to achieve a 60-80 mil (1.5-2mm) (DFT) membrane. Apply next coat when dry to touch and nothing is wet underneath; tacky is okay. Generally 4-6 hrs between heavy coats. Amounts vary depending on surface roughness. Use all material up to achieve a long lasting membrane. Avoid hot, direct, intense sunlight during application. Remove Painters Tape while still wet. Membrane will turn brown in ponding situations due to surfactants. Will dissipate over time as the water cycles and cleans.Clean Up - Use soap and water or mineral oil to clean skin. - If you need to return anything, contact us to initiate a return. We ask the material be unopened, in new condition and you ship the product back to us within 90 days.

Review: I did give it a 5 despite one issue- The positive first - Had a leaky flat roof (slightly racked) over my garage - Was going to have it done professionally for over $5000 ish. To replace the existing membrane. Well Liquid Rubber has a help line email so I asked them if this product would work well - and gave them details of my roof etc. - I got an immediate response and then ordered 10 gallons, based on the surface area etc. This was my bad - but to do I believe the recommended 5 coats it took about 6 gallons - since this stuff is bit pricey I could have ordered 5 gallons and 1 gallon and saved $. Good news is the roof did not leak anymore, and looked good. Here was the complaint- I had left a black rubber garden hose on top of the garage months after applying the sealant- maybe it was up there in the middle of August for 3 weeks- Well when I went to remove the hose it was stuck to the roof - It was not that hard to pry it away but it actually left kind of a stain on the roof. So my bad for leaving the hose there but I did not expect that. I have to check but I will have to do this again at some point-
Review: Great stuff very impressed . I sealed my steal trailer . Spread easy , went a long way , dried fast and saved me a lot of money taking it somewhere to be done .

## Questions & Answers

**Q: How long does new concrete need to cure before applying liquid rubber?  We are sealing our new concrete pond with this product = will not have fish in**
A: New concrete needs to cure as per the installation instructions.  Applying any of the Liquid Rubber products or most waterproofing products prior to a full cure may compromise the curing process of the concrete.

**Q: I have a black plastic pond i got from home depot. will it adhere to that material?**
A: Yes, put a few coats on. Let each coat dry well (24)hrs . You can spray on inside of pond. I used a undercoating product used for undercoating cars for the outside of pond. I put 3 coats on. I let each coat dry for 2 days before applying the next coat. All worked great my pond is like new and no leaks and all of my goldfish are fat and happy! Good luck! Take your time and cover every spot even sides. Make sure the pond is very clean before u start applications. I used a ruff kitchen pot scrubber to scrub clean.

**Q: Does this project leave much of an odor after it has set?**
A: Haven't smelled any odor. When putting it on there is a usual rubber smell like a basketball, but it doesn't seem to last very long. And it  smells just like putting rubber on, which wasn't bad. It works for me.

**Q: what color is it when it dries?**
A: The product is brown when it is wet and black when it dries.

### ⭐⭐⭐⭐⭐ Review
*by D***N on 20 September 2025*

Absolutely blown away by this product. I was used to those roof sealers made out of tar that never really dried, but just dried out. This product dries to a phenomenal rubber shield and it sticks to anything it comes in contact with. A slight word of caution. It took me several hours to clean out my spray gun after unsuccessfully trying to spray it with my airless sprayer. There seems to be no mention of any product that will act as a solvent for removal. Baby oil, patience and elbow grease is what it needed. After the spray gun fail, I purchased and threw out afterwards, some cheap dollar store brooms for application on my courigated metal roof. Recommend at least 3 coats for a lasting, worry free, seal.
