RV LeakGuard – Roof Repair & Sealant

To stop leaks, apply Pella RV Roof Repair on any holes or leaks you need to waterproof: screw heads and screw holes, seams from overlapping panels, around air-conditioner installs, solar panel brackets, vents, skylights, tv/radio antennas, satellites. It’s a mastic—a thicker material that will seal into a tough, durable, heat-reflecting, and UV-resistant waterproof repair. To be used before coating the entire roof with Pella RV LeakGuard Roof Top Coat.

Easy to Apply!

  1. To stop leaks, apply Pella RV Repair and Sealant on any holes or leaks you need to waterproof: screw heads and screw holes, seams from overlapping panels, around air-conditioner installs, solar panel brackets, vents, skylights, tv/radio antennas, satellites. It’s a mastic—a thicker material that will seal into a tough, durable, heat-reflecting, and UV-resistant waterproof repair. Apply to targeted fastener/seam/roof penetration and also to the local surrounding area, 3–4 inches past targeted area is usually desirable. The goal is to create a seamless layer of waterproof material that both seals the targeted area and bonds to the surrounding surface.
  2. For a full seal of your entire roof, now apply Pella RV LeakGuard Top Coat. Work from front to back—it’s just like painting a room. Use a brush or roller to coat the entire surface of your RV or trailer roof. Generally, you’ll want to lay down a skim coat (a very thin layer, where you can still see the underlying roof color), and then a first coat (approx. 10 mils thick), and then a second coat (also approx. 10 mils thick) for a waterproof, seamless membrane that keeps your RV cooler in the sun and dry in the rain. Prevent leaks and seal your roof with a clean, bright white coat of Pella RV LeakGuard Top Coat.

With over a 25-year history of success, RV LeakGuard has helped thousands get a new roof for a fraction of the cost of roof replacement. RV LeakGuard is specially formulated for RVs, trailers, and mobile homes that demand a tough, highly flexible, and season-resistant roof coating, as our customers travel throughout the year. Its unique chemical and application characteristics have made it the clean, bright white roofing membrane of choice for our customers.

Acceptable Roof Types

One of the unique characteristics of RV LeakGuard is that it has been specially formulated to be compatible with 95% of roof surfaces without needing a primer, saving the RV consumer time, complexity and money. This makes RV LeakGuard a one-step process for putting an end to roof leaks.

The surfaces below are compatible with RV LeakGuard:

  • EPDM
  • Can be applied directly over non-silicone products such as Dicor, Kool Seal and elastomerics
  • Alpha rubber roof made by Fleetwood RV
  • Fiberglass
  • Butyl Rubber
  • Hypalon Rubber
  • Vinyl – as long as it is aged. An adhesion test is required.
  • Metal
  • TPO
    1. TPO must be cleaned specifically with Pella SuperClean Cleaner/Degreaser found on our site.
    2. TPO must have a remaining service life. TPO scrim must not be visible throughout the field of the roof.
    3. The surface must be absolutely dry. Wiping the surface dry is not enough, all water must be evaporated from the surface. Do not apply in the early morning, as morning dew may affect the application. Trapped water can cause the material to blister/wrinkle

NOTE: Cannot be applied over silicone-based coatings
Wood: An oil-based wood sealer is needed on any wood surface as well as two coats of the RV LeakGuard. Please wait 24 hours between coats. Since we do not know the quality or condition of the wood, any wood application is not covered by a warranty.

For any other substrates, please contact our office prior to application. If you want to perform an adhesion test, begin by coating a small area (1′ X 1′) and embed a strip of mesh in the test area. Saturate and coat over the mesh, and allow 48–96 hours of cure time. Once dried, pull upwards on the mesh to test the adhesion strength of the coating to the substrate.

Description

RV LeakGuard is a solvent-based, single component moisture cure coating specifically formulated for the RV industry.

  • Contains fungicides and mildewcides.
  • Superior adhesion to various substrates.
  • Reflective roof coating helps reduce cooling costs, prevents UV degradation and premature roof failure.
  • High tensile strength and elongation.
  • Excellent protection for polyurethane foam.
  • Improved UV resistance and reflectivity.

Care and Maintenance

For maximum performance and overall service life for your RV, inspect your roof regularly. Keep the roof clean and free of oils and debris to maximize protection and performance. Touch up any damaged areas caused by branches or limbs immediately to prevent additional substrate deterioration.

CAUTION: RV LeakGuard may be slippery when wet. Exercise caution when walking on roof system.
Note: This is important, particularly when walking on light-colored surfaces, as any ice or frost may not be directly visible.

Preventive Maintenance

  1. Ensure Proper Drainage: By periodic inspections of the roof surface and by cleaning any leaves, twigs, and other debris that may accumulate over time, you will be extending the life of your roof system. Ponding water on the surface of the system will increase the probability of moisture entering the structure BUT only as a result of a puncture or cut caused by physical damage. RV LeakGuard will withstand ponding water 365 days a year.
  2. Limit foot traffic: RV LeakGuard will certainly take light traffic, but we do not recommend heavy foot traffic. Any unprotected areas of the surface are more susceptible to damage from constant foot traffic.
  3. Avoid harming and/or breaking down RV LeakGuard by exposing the finished coating to harsh chemicals, particularly those containing petroleum products. Wash roof with Degreaser/Cleaner available on our order form. Many RV cleaners sold in RV retail stores can also be used. Refrain from using solvents, and use caution when using grease for lubricating your AC or vent hinges. Prolonged exposure to these materials will cause swelling and possible degradation of the system if spills are not removed.
  4. Avoid puncturing the system. Be sure to protect the roof from puncture and any abrasion. In the event of damage. Clean roof thoroughly to remove any dirt and recoat the affected area.
  5. When snow is on the surface, use only a plastic shovel to avoid cutting into the membrane. Most snow removal damage occurs when shoveling around your AC and vents.

Periodic Inspections

  1. Bi-Annual (twice a year) roof maintenance and inspection are suggested for your RV roof. This is not only to inspect the roof coating but the entire roof, noting any maintenance issues related to drainage, roof vents, and other penetrations; likely areas for future roof issues.
  2. Inspect the roof deck from the underside for evidence of leaks, deteriorated decking, structural cracks, movement, or other deficiencies. Parapets and edgings should also be examined for evidence of cracking, deterioration, and moisture infiltration.

In addition to the above inspection, you should also inspect the roof in the following situations:

  1. The RV was exposed to severe weather, such as very high wind or hail.
  2. Examine the roof for severely ponded conditions, debris, and any other damage that may allow moisture to collect. The roof should be examined in areas where damage has previously been identified for punctures, tears, or loose coating.

Cleaning

  1. Pella SuperClean Cleaner/Degreaser Roof Cleaner was field-tested to be compatible with RV LeakGuard and won’t void the warranty. We suggest two cleanings a year.
  2. Coated surfaces must be inspected and cleaned bi-annually to maintain reflectivity, maximum longevity, and minimize chances of any deterioration of the coating due to environmental factors (such as accumulation of dirt).
  3. Before and after cleaning the surface, it is important to inspect the coating to see if there are any tears or blisters that need repair.
  4. If any tears or blisters are found, it is important to document where these are on the surface to identify recurring issues.
  5. Manual Cleaning: Depending on the type of debris on the coating, you may be able to use a simple garden hose with a spray nozzle and a very soft bristle deck brush to remove the debris.
  6. Pressure Washing: Use a white (40 degree) wide nozzle tip with a maximum 2000 psi pressure washer. Start with the tip at 18” off the deck surface and saturate the area with water. Generally, “softening” the debris will allow for less chance of damage to the coating. Come back to the area and gradually lower the tip to the deck until you see the debris coming off but do not allow the tip to get lower than 6” from the deck. Warranties will not be covered on premature erosion related to abrasion caused by excessive pressure.
  7. Stains: If the coated surface has discolored, consider recoating the roof to refresh it.

Application

Existing Elastomeric Roofs

For elastomeric liquid rubber roofs, apply a “flash coat” (a very light coat) approx. 300 sq. ft /1 gallon. Then, let the flash coat dry for at least 24 hours. Cooler temps or high humidity may slow cure times. Then apply the main coat at 100 sq. ft per gallon, resulting in 16 mil thickness (8-10 mil dry). Wait for the first coat to dry, and finally, apply 2nd coat (same thickness as the first coat). Note: If the flash coat or main coat is not completely dry before the application of the next layer, continue to wait before proceeding; solvents are still gassing off and the substrate may wrinkle from trapped gasses. (Wrinkles will settle out over time).

The substrate to be coated MUST be dry initially. Once applied, the product can handle a light rain after three hours, assuming temps above 55 degrees. If any moisture is present upon application, there will be blistering. (Blisters can be cut away and the area recoated). If using a power washer to clean the roof, we suggest waiting seven days before coating (if you are applying over a rubber roof). If the roof is lightly cleaned with a brush and minimal water, then coat in two to three days assuming those days were dry.

Roof Preparation and Application Process

We suggest performing an inspection of your roof. Look for any separations in seams. Also, around your joints, A/Cs and vents, check for any loose caulk or areas where caulk may be needed. Our Roof Repair and Sealant has been field-tested to be compatible with RV LeakGuard, so it will not void the warranty. Be sure any silicone caulk currently on the roof is replaced with the Roof Repair and Sealant.

A light power wash, if you have one, is great. Otherwise, use a good bristle brush. The roof must be clean, dry, and free of any oil, grease, dirt, or loosely adhered coating. We suggest Pella SuperClean Cleaner/Degreaser to thoroughly clean your roof and ensure superior surface adhesion. It is field-tested to be compatible with RV LeakGuard and won’t void the warranty. The Cleaner/Degreaser emulsifies contaminants and provides improved surface preparation by effectively removing oil, grease, mildew, dirt, and other soils from your roofing membrane. You can also use the Cleaner/Degreaser annually to further protect your roof, allowing dirt and grease, etc. to be removed, further extending your roof service life.

RV LeakGuard is applied at approximately 100 sq. ft per gallon. The easiest way to accomplish this is to mark your roof into 10′ X 10′ areas. Once you are done filling in one of those areas, you should be finished with a gallon of RV LeakGuard. Be sure your roof is perfectly dry (not just wiped-dry, and ensure the absence of morning dew) before application. Many customers tape off their roof with blue painter’s tape to cut clean, delineated lines at the edges of the roof coating and to avoid runs. If coating a slightly vertical section of the roof, the tape can be formed into a gutter to catch drips and prevent spills down the side of your RV.

RV LeakGuard is ready to use out of the can; thinning is not required. Mix for approximately five minutes with an electric drill stirrer. Application of the product is with a brush or medium nap roller (3/8 inch) (not a foam roller), and chip brush around corners and vertical surfaces. Be sure to put the lid on the can while you are applying the product. Failure to do so will allow the product to cure and thicken. The product has a three-year shelf life as long as you affix the lid properly, so air does not get in.

Average dry time: Dry to touch in 3–4 hours. Wait a full 24 hours before traveling. Should you choose to apply a second coat, wait 24 hours. Rain should not be in the forecast on the day you apply the product. However, should a very light rainfall within 2–3 hours of application, the roof is already protected. You may see rain dimples on the surface, depending on the strength of the rain. If seams are not properly adhered, it may cause the tape to bubble up or raise as will a rubber roof that has lost adhesion to the wood substrate. Applying the product too thickly in one coating may cause wrinkling of the substrate – two thinner coatings are recommended.

This product is meant for outdoor applications. If applied indoors, ensure excellent ventilation and utilize a NIOSH respirator, available at Home Depot or Uline. As the product begins to dry any brush or roller marks will disappear and become a seamless coating. It will be as if someone installed a custom fit piece of membrane, just for your RV. Apply today and drive away tomorrow! It’s that easy. Clean up drips and spills with Xylene, available at any paint store.
