- Is one gallon enough for my RV roof?
- That depends on roof size and how thick you apply it. Most liquid rubber coatings cover roughly 50 to 100 square feet per gallon at the recommended thickness, so measure your roof and plan on two coats. For a full-size motorhome roof, expect to need several gallons.
- What roof types does it work on?
- Liquid rubber coatings are typically used on EPDM, TPO, fiberglass and metal RV roofs. Clean the surface thoroughly and let it dry before applying. Do not apply over silicone sealant or a wet roof.
- How long does it take to dry?
- Most liquid rubber roof coatings are touch-dry in a few hours and ready for a second coat in about 4 to 6 hours, with full cure in 24 to 48 hours. Check the label on your container and avoid applying before rain.
- Does it come with primer or tools?
- No. The listing is for the one-gallon can of coating only. You supply the cleaner, primer if needed, brush or roller, and any seam tape.
- Is it cheaper than name-brand RV roof coatings?
- Budget brands often list below established names like Dicor or Heng's, but per-gallon price is only part of the cost. Compare coverage per gallon and warranty terms before deciding.
