Primer 1217 – Maxisil

Maxisil Primer 1217 is a fast‑drying, clear surface conditioner designed to maximize the bond of silicone caulks & sealants to difficult, non‑porous substrates. By priming before you caulk, you create a secure, long‑lasting joint that resists water, chemicals, and daily wear.

Key Benefits

• Superior adhesion – promotes up to 30 % stronger bond on PVC, fiberglass, aluminum & more.
• Fast drying – ready to seal in as little as 10 minutes, keeping projects on schedule.
• Invisible finish – dries clear so it won’t discolor surrounding tile or stone.
• Low VOC formula – compliant with current environmental regulations.

Where to Use

Application Instructions

1. Clean joint surfaces thoroughly, removing dust, oil, and old sealant.
2. Shake Primer 1217 well and apply a thin, even coat with the supplied brush or lint‑free cloth.
3. Allow to flash off for 10–15 minutes (surface must feel dry to the touch).
4. Immediately apply the chosen Maxisil silicone within 4 hours for best results.

Coverage & Packaging

One 250 ml bottle covers approximately 160 ft² (15 m²) depending on porosity and application method.

Pro Tips

For expansion joints in wet areas, pair Maxisil Primer 1217 with Maxisil Wet Area Silicone for a watertight, mildew‑resistant finish.
