  • Step 1:

    Ensure the surface is free of any oils, minerals or loose materials before application.

    Wash and clean the entire surface. Use a power washer.

  • Step 2:

    Cover and Sandwich the RTT - GEO Textile with the RTT - Waterproof Sealant over seams, vents, joints and around skylights, outlets and AC. Apply RTT - Quick Dry on the RTT - Waterproof Sealant to speed up curing and to protect the sealant from approaching rain.

    Allow to cure for 24 hours.

  • Step 3:

    Apply 1-2 coats of the RTT - Waterproof Sealant to the entire RV - Roofs. (Allow to cure 4-6 hours between coats)

    Allow curing for 24 hours.

  • Step 4:

    Apply RTT - Primer/Sealer on top of the RTT - Waterproof Sealant with a 0.2L/m² (5m²/L) rate. 

    One coat @ 100 - 200 micron is sufficient.

    Allow curing for 2 hours before the next step.

  • Step 5:

    Apply 2-3 Coats of RTT - Protective Top Coat on top of the primed sealant coating.

    Allow 4 - 6h to cure in between coats.

  • Trade Tipp:

    - This Top Coat should only be applied in warm weather over 20*C. To avoid bubbling and non-curing, DO NOT apply products when there’s dew, cold wind or rain!

    - If your RV is still under warranty be sure to contact the manufacturer to ensure you do not void the warranty.

Why do i need the GEO Textile?

The GEO Textile is sandwiched with the Waterproof Sealant over cracks, holes, seams, vents etc. It is used for reinforcement and stabilisation purposes.

What is the Seam Tape for?

The Seam Tape is used to cover bigger holes and cracks as it is firmer than the GEO Textile. Like the GEO Textile, it is used for reinforcement and stabilisation purposes.

Why do I need the Quick Dry Spray?

The Quick Dry Spray is optional. However, we recommend spraying it on top of a wet Waterproof Sealant layer for a quicker cure and to protect the product from approching rain.
