Sealing Joints in Interior Applications:

When working on interior projects, the appearance of joints is critical to achieving a professional paint finish. Even minor gaps, cracks, or dents in gypsum‑board, cornices, or skirting boards can compromise the final look if not treated correctly. Acrylic sealants remain the most commonly used solution for painting projects, providing easy application, water‑based convenience, and excellent paint adhesion. 

Hybrid sealants, such as Gorilla MS, combine paintability with superior elasticity, making them suitable for areas where movement may occur or surfaces are exposed to stress. For seamless interior finishes, Soudal’s Pro Gaps range provides versatile solutions: Pro Gaps Fill & Paint is the multipurpose filler for general crack and gap repair, Pro Gaps Quick Dry allows rapid application and painting, and Pro Gaps Light Speed offers a sandable, smooth finish for fine detail work. 

These products ensure long‑lasting adhesion, minimal shrinkage, and compatibility with most interior paints, preventing cracks or flaking in the paint layer. Their flexibility and durability make them perfect for all interior sealing projects, from small touch‑ups to large‑scale renovations.
