Stelmax 1961 Gap Filler & Sealant – High‑Strength PVC Filler for Larger Gaps (300ml)
Stelmax 1961 Gap Filler & Sealant (300ml) is a professional‑grade, high‑solid PVC filler designed for creating exceptionally strong, maintenance‑free joints on rigid and plasticised PVC. Formulated with PVC resin, pigments and plasticisers, it delivers outstanding adhesion and is widely trusted across the window and building industries for frame installation, sealing and attachment work.
Thanks to its high solid content, Stelmax 1961 is ideal for filling larger gaps where a durable, long‑lasting finish is essential. Once cured, it forms a tough, water‑resistant, UV‑stable seal that closely resembles high‑quality rigid PVC. It also adheres effectively to many porous substrates, making it a versatile choice for both installation and repair tasks.
Available in White and Mahogany, with RAL colour matching available on request, Stelmax 1961 offers a clean, colour‑matched finish for a wide range of PVC profiles and trims. The 300ml tube fits any standard sealant gun for quick, easy application.
