Achieving a Perfect Finish with Paintable Joints:
For interior projects, a clean paint finish depends on using the right paintable joint sealant. Cracks, uneven edges, or poor adhesion can ruin the appearance of freshly painted walls or trims. Acrylic sealants are the most common solution, offering easy application, fast drying, and compatibility with most water-based paints.
Soudal’s Pro Gaps range includes high-quality fillers specifically designed for painting and finishing work. Pro Gaps Fill & Paint is the all-rounder, a flexible, multipurpose filler that levels joints, fills cracks, and creates a smooth, paint-ready surface. When speed matters, Pro Gaps Quick Dry is ideal, drying rapidly so you can move from filling to painting in one go. For a fine finish that can be sanded and shaped to perfection, Pro Gaps Light Speed Filler offers superior smoothness and minimal shrinkage once cured.
Hybrid sealants, such as Gorilla MS, also provide paintability combined with excellent elasticity and adhesion, making them suitable for more dynamic areas or where surfaces may move slightly. For outdoor or glazing applications, select a specialised hybrid or polyurethane-based sealant for long-term flexibility and UV resistance.
