Introduction

• RV roofs are notoriously known for leaking. Liquid Rubber RV Roof Coating provides an easy Do-It-Yourself solution to keep your RV dry.
• The coating seals and protects the RV roof against changing temperatures and UV rays.

Before You Begin

• Identify your RV roof material to ensure proper application of the Liquid Rubber RV Roof Coating. Common materials include EPDM, TPO, Metal/Aluminum, Fiberglass, and PVC/Vinyl.

Pick the Right Primer

• For EPDM or TPO – Use Liquid Rubber EPDM/TPO Primer.

Inspect Roof

• Before applying the coating, inspect the roof for any loose sealant, caulking, cracks, or signs of damage.
• Ensure the roof is compatible with the coating by performing an adhesion test if necessary.

Weather and When to Apply

• Apply the coating in dry, warm temperatures above 10C/50F, avoiding wet conditions, direct intense sun, and high humidity. Ensure the surface is at least 5 degrees above the dew point before application.

Set Up Your Workspace

• Maintain a clean workspace by using a tarp or cardboard to place containers and tools, wrapping tools in plastic, and properly cleaning any spillages.

Preparation and Cleaning

• Roughen the surface with 120-grit sandpaper, clean with Liquid Rubber RV Smart Cleaner, and use masking tape for areas not to be painted.

Detail Work

RV ROOFS ARE NOTORIOUS FOR LEAKING

Whether it’s a vent, skylight, tear, or slide, it seems to never end. Eliminate the need for costly service calls with Liquid Rubber RV Roof Coating, the easy Do-It-Yourself way to keep your RV dry. You can keep your RV roof leak free with a roof coating that seals and protects the surface to withstand changing temperatures and reflect the sun’s heat and damaging UV rays.

STEP 1: BEFORE YOU BEGIN

IDENTIFY YOUR ROOF

The first step of using RV Roof Coating is to determine your roof’s material. Here is how to determine RV roof type:

1. EPDM – Smooth & rubbery. White top and black bottom.
   Most common RV Roof material.

2. TPO – Textured & plasticky. Same color top and bottom usually.

3. Metal/Aluminum – Looks like a metal roof.

4. Fiberglass – Smooth hard gel-like surface.

5. PVC/Vinyl – Smooth & plasticky. Same color top and bottom.

If you’re not sure of your RV roof type, take some pictures and email them over to Support@ShopLiquidRubber.com We can walk you through the whole process.

PICK THE RIGHT PRIMER

1. EPDM or TPO – Liquid Rubber EPDM/TPO Primer.
2. Vinyl/PVC, Fiberglass or Aluminum – Use Multi-Purpose Primer.

INSPECT ROOF

You can apply over clean, well adhered Lap Sealant (not silicone). If there is a coating on the roof, an adhesion test is recommended. Please contact us to ensure compatibility.

1. Remove loose, flaking lap sealant.
2. Remove any Silicone Caulking (usually clear or opaque and rubbery).
3. Check for cracks or seams pulling back, or coming loose.
4. Look for signs of cracking, peeling, or bubbling.

STEP 2: ONCE YOU HAVE YOUR SUPPLIES

WEATHER & WHEN TO APPLY

• Apply in dry, warm temperatures
• 10C/50F and above, including overnight temperatures
• Do not apply in wet conditions or if rain, fog or dew is forecasted within 24 hours
• Out of the hot, direct and intense sun
• Below 80% humidity
• Make sure what you’re coating is at least 5 degrees above the dew point of the environment (Click here for more info)

SET UP YOUR WORKSPACE
Stay organized and limit clean-up by following these setup tips:

1. Set out a tarp or large piece of cardboard to keep containers and tools on when not in use.

2. If there is a spillage, soak up as much material as possible with rags.

3. Clean your spillages with soap and water as much as possible.

4. If the spillage dries, scrape it off with a razor/scraper/etc, use mineral spirits/white spirits to weaken the product, and then scrub with a wire brush.

5. Wrap tools in plastic to keep them moist in between coats (kitchen wrap is fine).
   Best to use disposable brushes and rollers.

6. Do not use solvents or solvent-based cleaners, adhesives, and paints near your working area.

7. Refer to the product Safety Data Sheet for personal protective equipment recommendations.

STEP 3: PREPARE THE AREA

PREPARATION & CLEANING

• For PVC, Metal and Fiberglass RV Roofs.
• Roughen the surface with 120-grit sandpaper
• For TPO RV Roofs
• Sand very well with 120-grit sandpaper
• Clean with Liquid Rubber RV Smart Cleaner for all roof types.
• Use masking tape for areas not to be painted and removed while the Primer/Coating is still wet. Apply masking tape for each coat.

STEP 4: DETAIL WORK
SEALING RV ROOF VENTS AND SEAMS

1. Wipe around edges and seams with acetone-soaked rag. *Do not pour acetone directly onto the roof.
2. Use Liquid Rubber RV Lap Sealant around smaller vents and seams and Liquid Rubber Seam Tape for larger areas that need to be bridged.
3. Prime around the vents and edges with appropriate RV Roof Primer. (Do not prime over RV Lap Sealant or Seam Tape)
4. When the Primer is dry (EPDM/TPO Primer is sticky when dry), apply a heavy coat of Liquid Rubber RV Roof Coating over the Primer, Lap Sealant and Seam Tape. Leave some of the Primer exposed so you can lap onto it later.

STEP 5: APPLY THE COATING

HOW TO APPLY RV ROOF COATING

1. Wipe one side of the roof lengthwise with Acetone acetone-soaked rag and apply Primer. Allow 1-2 hours to dry (Primer will remain sticky/tacky).
2. Apply RV Roof Coating in a heavy coat over the Primer leaving 4-6 inches of the Primer exposed.
3. Once RV Roof Coating is dry (6-8hrs) and you can work on it, wipe the other side of the roof with Acetone and apply Primer.
4. Apply RV Roof Coating in a heavy coat over the Primer.
5. Once dry (6-8 hours) and you can work on it, apply additional coats in opposite directions until you use up your final recommended coverage. ie. 5 gallons for a 30 ft RV.
6. Before applying the final coat, inspect for any differences in thickness, pinholes, or blisters and repair if necessary.
7. Remove any masking tape while the coating is still wet.
8. The final coat cures in 48-72 hours.

TIPS & TRICKS

• Use disposable gloves
• Use throw-away brushes and standard 3/8” (10mm) rollers
• Do not let products freeze in their containers
• Some previously applied coatings/ sealants/paints may affect adhesion Contact us if you are unsure
• Mix products well before using
• If you allow your coating to dry too much, you can score/cut along the tape line before pulling to prevent lifting the coating
• Speak to Liquid Rubber Tech Support with any questions: 1-855-592-1049
