Butyl Rubber Roof Sealant Uses

roof sealant

Liquid Butyl Rubber is ideal to recoat existing roofs and add a significant number of years to the life of a roof. In fact, our customers have described it as essentially getting a new roof for a fraction of the cost, since, for most roof types, this is a single application with significant cost savings when compared to multiple coat systems. The cost savings alone have made it the choice for thousands of our customers over the years. Labor costs are also decreased since you only need one coat versus 3-4 with other systems. Below, you will find the roof types that are compatible with Liquid Butyl Rubber. . We suggest if you have any doubts about your particular roof, or your particular roof type is not listed, conduct an adhesion test prior to application. We are not responsible for improper roof preparation prior to application.

  • Various Metal Roofing systems
    • Weathered Galvanized
    • Galvalume (must be aged min 8 years)
    • Aluminum
    • Weathered copper
  • EPDM
  • Any original EPDM rubber roofing system.
  • Fiberglass
  • Hypalon
  • Karnak asphalt exterior coating (be sure to remove any loose material first)
  • PVC - Please visit our high volume Silicone product page
  • Grace Ice and Water Shield.
  • Acrylic Sheet and any acrylic based product
  • Weathered Vinyl
  • (Aged) Polyurethane Foam
  • Torchdown
  • Tar and Gravel
  • Modified & BUR roofs
  • Concrete, where there is little foot traffic (consider moisture test. If moisture is present bubbling may occur)
  • Can be tiled over (can be applied over thin-set)
  • Any roof where a 3rd party coating such as an elastomeric or acrylic was previously applied.
  • TPO-Must be aged five years.
    1. TPO must be cleaned with our Roof Protect found on our site
    2. TPO must have remaining service life. TPO scrim must not be visible throughout the field of the roof. If very light scrim is showing we suggest ordering our TPO Base coat.
    3. Surface must be dry. Any of these could cause the material to blister/wrinkle
  • Sprayed Urethane Foam Roofs- Be sure roof is dry. Moisture will cause coatings to blister (Call for tech support)
  • Any other application must be approved in writing
  • NOTE: Not to be used for 3rd party silver-asphalt based coatings unless entirely removed

Avoid applying over SILVER based asphalt-coatings such as blackjack, They must first be fully removed from the substrate prior to the application of our product.

NOTE: Not to be applied over PVC roofs or silicone coatings. After application for any ponding water areas of the roof we suggest sweeping any standing water that occurs 8 hours after application, so the Liquid BUTYL Rubber has a full 13 days to dry out. This is ONLY needed in the ponding water areas. Failure to do so may cause delamination.

Liquid Butyl Rubber offers significant tensile strength, elongation as well as other technical attributes which can be found on our “Technical” page.

The above are only guidelines. Any applications related to chemicals should be tested thoroughly before putting in service.

There has been no other product to match the durability of Liquid Butyl Rubber in the Roof Repair Products industry. Because Liquid Butyl Rubber is solvent-based it can boost the broad temperature tolerance we have been speaking about. This is not the same case for water-soluble products like elastomerics, acrylics or urethanes. If it were to light rain unexpectedly just a few hours after you applied Liquid Butyl Rubber, it will not harm the application and curing will resume when the water has evaporated. Once applied, Liquid Butyl Rubber will not wash off.

FOUNDATION Leaks and Sealing

Liquid BUTY Rubber has been used extensively over the years to provide a watertight seal on new and existing foundations. Builders have relied on the product as their “Go-To” product of choice due to it ability to chemically bond to the concrete allowing for a very strong bond while still maintaining its flexibility when fully cured. Cracks should be filled first with our SeamTIght product prior to applying our Liquid BUTYL Rubber. A solid foundation is the backbone of any structure, bearing the weight of the entire building above it. However, even the strongest foundation can be compromised without proper protection against water infiltration. Waterproofing a foundation is not just an optional add-on; it's a crucial step in ensuring the longevity and stability of any building. Here's why it's so important.

Water damage is one of the leading causes of foundation deterioration. When water seeps into the foundation, it can weaken the concrete, leading to cracks, erosion, and even structural instability over time. By waterproofing the foundation, you create a barrier that prevents moisture from penetrating the concrete, thus safeguarding its integrity against the damaging effects of water. Water intrusion doesn't just affect the foundation itself; it can also wreak havoc on the entire structure. Moisture in the foundation can promote the growth of mold and mildew, which not only poses health risks but can also compromise indoor air quality. Additionally, water infiltration can lead to dampness in the basement or crawl space, creating an ideal environment for pests such as termites and rodents.

Beyond structural concerns, waterproofing the foundation can also save you significant time and money in the long run. Repairing water damage to a foundation can be a costly and disruptive endeavor, often requiring extensive excavation and reconstruction. By proactively waterproofing the foundation, you can avoid these expenses and inconveniences, ensuring that your building remains sturdy and secure for years to come.

Waterproofing isn't just for new constructions. Even existing buildings can benefit from foundation waterproofing as a preventative measure against potential future water damage. The importance of waterproofing a foundation cannot be overstated. It's a fundamental step in safeguarding your investment and ensuring the long-term stability and durability of any structure. By taking proactive measures to waterproof your foundation, you can protect against water damage, preserve indoor air quality, mitigate pest infestations, and save yourself from costly repairs down the line.

dhruv WHY IS LIQUID BUTYL RUBBER THE BEST CHOICE?

If you are not using Liquid Butyl Rubber your roof is not getting the best roof coatings it deserves. Over a 25 year history of success, it has proven to be the best and most versatile coating on the market.

When looking for a long-term solution to your roof leak or extending your roof's life another 18-20 years, it is critical to choose the correct product the first time, so you don’t have to repeat the process later. We outlined several key benefits and characteristics of our Liquid BUTYL Rubber in the above bullet points. Equally important is looking at the overall cost. For example, what is cost per square foot and the resulting mil rate when dry? The thicker the mil rate the more protection and years added to your roof’s life. Does it require a primer or multiple coats? Why add unnecessary weight to a roof by using multiple-coat systems? These questions will not only determine the overall price you are paying for the product but also the additional installation costs assuming you are not applying it yourself. Our Liquid Butyl Rubber is a one-coat process, saving you time and money. There are no primers needed, so when you add up the cost of other systems that require primers and multiple coats, you have far exceeded the cost of Liquid Butyl Rubber. Also, our product is a solvent-based system not water-based making our product a superior choice. Why? Because Solvent-based coatings are significantly less susceptible to climate conditions, freezing temperatures and have a very high resistant to extreme weather conditions. Liquid Butyl Rubber will withstand ponding water literally 365 days a year! So, for everyone with a flat roof the choice should be clear.

Liquid Butyl Rubber has a thicker consistency that other coatings and results in a 20-mil film thickness. Other coatings may require 2 or 3 coats to achieve the same thickness. One of the main characteristics that makes Liquid Butyl Rubber so unique is in the chemistry of the drying process. As the product dries it chemically cross-links, creating a chemical bond whereby our coating and your roof fuse together to literally will become one in the same. Also, during the drying process the product will force out, and up to the surface, what would otherwise be trapped air (in other types of roof coatings). This is the reason other coatings have a tendency to crack after a few years especially elastomerics and water-based coatings. Our Liquid Butyl Rubber has a 500% elongation and over 1520 psi tensile strength allowing it to handle any roof that expands and contracts due to temperature changes. When the product dries what you have is a smooth seamless membrane.

Liquid Butyl Rubber can be applied directly on more types of roofs than other coatings on the market without the need for special primers. It has been the #1 roof coating recommended time and again by contractors throughout the USA. It is an economical and long-lasting solution, a proven alternative to roof replacement.

Liquid Butyl Rubber is applied in one coat at a 20-mil film (50 sq. ft per gallon) thickness and will still withstand extreme temperatures. That is the beauty of the product. Radical extremes in temperature where constant surface temperatures reach 250°F or above or -40°F or below is not an issue for this product. There is no need for a second coat. 1 gallon covers 50 sq ft and a 5 gallon covers 250 sq ft. Customer is responsible for determining their square footage.

25 years of field study and thousands of satisfied customers have made Liquid Butyl Rubber the roof repair solution for many applications. Liquid Butyl Rubber is so versatile it can easily be applied to metal, rubber, fiberglass, concrete, Hypalon TPO, BUR, foam and many other surfaces. Liquid Butyl Rubber has proven to outlast acrylic, urethane and elastomeric by a factor of three. There may be lower-cost products on the market, but none that have the long-term durability, waterproofing ability and tolerance to extreme temperatures like Liquid Butyl Rubber or EPDM Coatings. Other roofing coatings require two to three coats, so not only does this triple your material cost but also triples your labor expense. If you are looking to add less weight to your roof with a one coat system that has proven itself over the years look no further. Here is a sample of just some of the companies who have use our products and have returned time and time again!

EPDM Coatings Cost Compared To The Competition

EPDM Cost Compared

Application of EPDM Coatings is easiest when the surface is flat, clean and smooth. Like all painting projects, the most time-consuming aspect is often cleaning, repairing and preparing the surface for application.



Liquid Butyl Rubber Roof Coatings

EPDM coatings has been featured in Article Insider, as well as Roofers Exchange, Building Service Management and recently won Metal Roofing Magazines product of the year. EPDM coating products have always been made right here in the USA. In addition, we source our suppliers from the USA as well. The product comes with the catalyst already in the can. Simply mix the product with a drill mixer and you are ready to apply. Application is with a 3/8-inch nap roller. Simply put the lid on the product to avoid air getting to it to avoid the curing process. For any material left in the can, fasten the lid tightly and you can store it for up to five years. For best results, the product should be applied between temps of 50-100° Fahrenheit. If you are using spray equipment; then 70°. The product requires daytime temperatures of at least 50° to cure. Temperatures can fall below 50°, and once they rise again above the 50° it will continue to cure. Roof leak repairs are an unwelcome reality to every owner of a residential or commercial building, mobile home or recreational vehicle. Roof leak repairs can involve almost anything, including replacing damaged shingles, mending holes, fixing roof leaks, or repairing dents with roof coatings.

Featured Customer Testimonials

EPDM coatings had asked us to put together a summary of a project we completed three years ago in Connecticut. The project consisted of recoating an existing 15,000 sq. ft. epdm roof. Approx. age 14 years. The existing roof began chalking and retaining water in many areas. Also significant separation within the seamed areas had developed. Our crew first power washed and vacuumed the entire roof. Next day we came back and sealed off all separated seams with the two sided Butyl tape and did all our prep work around the seams, chimney's etc. Total project took 74 of the 5 gallon pails cost of materials was approx. $1.32 per square foot. Two other systems we explored was an acrylic elastomeric requiring two coats of material cost .55 per square foot so essentially 1.10 for the two coats and a butyl coating that require a primer. Both products there were at $1.43 a square foot. This does not include labor just material costs. Labor costs would have been about 2.2 times higher with the other products. We had spent two months over the summer going back and forth with the owner and researching what we were going to use for this roof and we had specific marching orders from the owner. They wanted a one coat system, did not want to have issues with ponding water and did not want to have to come back in a few years to repair it. After this first job we do not use any other product; hands down. There are many reasons but in the interest of time here you go. First it is the only roofing product in the U.S that is warrantied on flat roof against ponding water and that right was the deciding factor. It is not some cheap water based acrylic or elastomer I think we all know how those work essentially recoating them every 2-4 years. The Butyl Liquid Rubber cures by product and as it cures the Butyl Liquid Rubber will chemically bond itself to the roof you are applying it on. We have not seen any product with that type of chemistry and bonding properties without giving up any tensile strength. This is why it can claim its 18-20 year life expectancy. It really is the only roofing material we have seen that immediately waterproofs. On our third day late in the evening we had a shower come through and we needed to stop for the day. We called the company with our concerns since we thought the material that was not dry was a total loss. We came back the next afternoon and the water evaporated and the product continued to cure. In addition a portion of that area is where the owner had a nasty leak which by the way stopped even though the product did not have sufficient time to dry. If your client is looking for solid performing product that you'll never have to worry about getting a call from them saying the roof is leaking then this is it. If your client is just looking for the cheapest thing to coat your roof this is not the product and my suggestion is to run from that potential customer you can not use cheap materials and expect them to hold up for any length of time; it is just not worth the reputation all of us work so hard to develop over the years.

EPDM

Stop making the same repairs using less reliable products that are not Butyl-based, are not UV and ozone resistant, and do not have flexibility built into the material (causing them to crack). Butyl rubber will expand and contract with any surface as seasons change and will not crack because of temperature fluctuations. Other products will begin to bubble and crack in less than two years.
