I would not think it would provide a good surface to paint, and flexing of the caulk would be a problem perhaps leading to wrinkling of the paint. Also, the surface is slightly "furry" whereas I normally try to achieve a clean, dry and smooth surface before painting. ## Frequently Bought Together - Frost King B2 Mortite Fingertip Caulking Cord, 1/8" x 90 ft, Grey - XFasten Transparent Window Weather Sealing Tape, 2-Inch x 30 Yards (50.8mm x 27.43m), Clear Window Draft Isolation Sealing Film Tape, No Residue - Transparent Window Weather Sealing Tape 2 Inch x 33 FT Weather Stripping Residue-Free Clear Window Insulation Tape for Doors Windows and Shower Glass Gaps --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/83681055-frost-king-available-b2-mortite-caulking-cord-19-ounce-90](https://www.desertcart.co.za/products/83681055-frost-king-available-b2-mortite-caulking-cord-19-ounce-90) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-06*
