Quick Dry Wall Repair Mortar | Fast Setting Cement-Based Patch Repair Compound
K12 is a premium dry-mix wall repair mortar made with specialty cement, fine aggregates, polymer additives, and functional fibers. It is designed for fast interior and exterior wall patching and sets hard in hours—not days—so you can continue the next step sooner.
K12 redefines wall repair speed. Initial set takes just 30 minutes, final set occurs in 1–2 hours, and it is ready for puttying, sanding, or painting within 2–3 hours. That is 80% less waiting time than traditional cement mortar. No need to leave a job site for days to allow patches to cure—mix it, apply it, and move on to the next step the same day. With coverage of 17–18 kg/m² at a 10 mm thickness and a 25 kg bag, you have everything needed to complete wall repairs in record time—faster turnaround, more jobs per week, and improved profitability.
K12 delivers professional-grade, long-lasting repairs. Its high-bond formulation penetrates deeply and adheres securely to concrete, brick, plasterboard, and more. With 1.5+ MPa tensile bond strength, it helps prevent hollowing, delamination, and call-backs. Reinforced with anti-crack fibers and polymer modifiers, it flexes with substrate movement rather than cracking. With ≤0.3% shrinkage, it supports a smooth, crack-free finish. Whether you are filling a 3 mm hairline crack or a 30 mm deep hole, K12 can handle both—one versatile, reliable product designed to last.
K12 performs as hard as you do, with no unnecessary effort. High water retention and excellent workability allow for smooth application, help prevent sagging on vertical surfaces, and enable a fine trowel finish with minimal effort—even for less experienced applicators. Its non-toxic, odorless formulation makes it suitable for indoor residential use, so both homeowners and contractors can work comfortably without concern for harsh fumes. Built with German technology and backed by ISO 9001 certified quality, K12 is the smart, safe, and dependable choice for all your wall repair projects.
