Cleaning the work surface

• Sweep the roof by removing dirt, dust, sand and other contaminants along the sides of the RV.
• Wash the roof along the sides of the RV with (or):
• pressure washer
• brush with hose if pressure washer does not work
• bucket and rag if pressure washer does not work
• coarse brush if no water is available at all

<aside> 💡

If the roof configuration does not allow for safe standing on its surface (due to a slippery or sloped area), the washing should be performed from a ladder. After that, use a special squeegee to remove any excess water.

</aside>

• Make sure the roof is completely dry before applying the coating. If necessary, use a brush, blower or wipe it with a cloth to remove any remaining moisture.

Preparation of Henry Pro-Grade 988 Silicone with Fiber for Seams

<aside> 💡

• Before transferring the silicone from the large bucket, thoroughly mix it with a drill-mounted mixing paddle for at least 2 minutes until the material is completely uniform.

If you plan to mix the silicone with fibers directly in the same bucket, first mix the silicone with the drill-mounted paddle, and only then add the fibers.

</aside>

• Mix no more than 1–2 gallons at a time. Gradually add the fibers into half a bucket of silicone, mixing only by hand with a manual mixer. This will help prevent clumping. Continue mixing until the silicone becomes thick and completely uniform — this mixture will be stronger, hold its shape better, and help prevent cracking.

Main process

<aside> 💡

If the membrane is not adhered to the base along the edges:

• Carefully cut the section of the membrane that isn’t adhered to the base along the side of the RV. Apply TPO Bonding Adhesive and press the membrane down. Let the adhesive dry for 2–3 minutes. Then you can apply the fabric tape. </aside>

• Apply fabric tape along the sides of the RV.

• Apply masking tape on both sides of the fabric tape to create clean edges and a neat appearance.

• Apply silicone: Use a brush (3-inch width recommended) to apply a layer of silicone with fibers over the fabric tape, spreading it evenly along the entire length.
