Sikaflex 715 RV Roof Sealant | 10.1 oz | White | 017-187690

Seal your RV roof seams, joints, and components with the Sikaflex 715 Semi Self-Leveling RV Roof Sealant (Part #017-187690, White, 10.1 oz). One-component silane terminated polymer (STP) sealant with excellent primerless adhesion to a wide variety of RV roofing substrates including EPDM, metals, and plastics. Purpose-built for roof sealing applications with strong UV resistance for long-lasting outdoor use.

Semi Self-Leveling for Clean Roof Application

The semi self-leveling formula is engineered specifically for roof sealing — it flows enough to fill joints and seams cleanly, but not so much that it runs off pitched surfaces. Delivers a durable, crack-resistant seal along all seams and joints.

Broad Substrate Compatibility

Excellent primerless adhesion to a wide range of RV roofing components:

• EPDM roofing membrane
• Metals: anodized and bare aluminum
• Coated steel: phosphated, chromated, zinc-plated
• Metal primers
• 2-part coatings
• Ceramics
• Plastics (see caution below)

⚠️ Plastic Substrate Caution

For plastics prone to stress cracking, seek the manufacturer's advice and perform adhesion tests on original substrates before use. This product is intended for experienced professional users — test with actual substrates and conditions to verify adhesion and material compatibility.
