How to Apply Dicor RV Roof Coating: A Step-by-Step Guide: 1 Minute to a Durable RV Roof with Dicor Coating

Dicor RV roof coating is a popular choice among RV owners seeking to protect, restore, and extend the life of their vehicle’s roof. Proper application is essential to maximize its effectiveness, ensuring your RV stays leak-free and looks great for many adventures ahead. This step-by-step guide will walk you through the process, from preparation to final touches.

Step 1: Inspection and Preparation

Begin by thoroughly inspecting your RV roof. Address any existing damages, such as cracks or holes, using Dicor lap sealant or another recommended product. Sweep away debris, leaves, and dirt. For best results, wash the surface with a suitable RV roof cleaner and let dry completely. Remove any old caulking that is peeling or loose.

Step 2: Mask and Protect Surroundings

Use painter’s tape and plastic sheeting to mask off edges, vents, and fixtures you do not want the coating to touch. Cover your RV’s sides and windows to guard from accidental splatters or drips during application.

Step 3: Apply Primer (if required)

Some Dicor systems require a primer—especially for non-EPDM surfaces. Check your product’s label. If needed, apply primer using a roller or brush and allow it to dry according to the manufacturer’s instructions.

Step 4: Mix the Coating

Open the Dicor roof coating and stir it thoroughly to achieve a consistent texture. Do not thin the product unless instructed by Dicor.

Step 5: First Coat Application

Using a heavy-nap roller (3/8” or larger), apply the first coat evenly across the prepared roof, working from one end to the other. For tight corners and around vents, use a paint brush. Aim for an even, continuous layer, minding the coverage as recommended by Dicor (often about 1 gallon per 125 square feet).

Step 6: Dry and Inspect

Allow the first coat to dry according to the instructions, typically 4-6 hours in ideal conditions. Once dry, inspect for missed spots or thin areas and touch up if necessary.

Step 7: Apply the Second Coat

Once satisfied with the first coat, apply a second, even coat as before. This ensures maximum protection and coverage. Let the roof cure for at least 24-48 hours before exposing it to rain or extreme conditions.

Step 8: Clean-Up and Final Touches

Carefully remove all masking tape and protective coverings. Clean your tools promptly, and admire your newly protected RV roof.

As a designer, I appreciate how a meticulously coated roof not only safeguards your RV, but also complements the interior ambiance by ensuring a leak-free, comfortable environment inside. If you’re visualizing complete transformations, leveraging a digital room planner can inspire further improvements, whether you’re upgrading furnishings, optimizing storage, or reimagining your RV’s living space from floor to ceiling.

Tips 1:

Work on a dry, clear day for best results. Wear protective gloves, and ensure adequate ventilation if working inside a covered facility. Store any unused Dicor coating in a cool, dry place for future touch-ups.
