What Is Siliconised Acrylic Sealant, and How Do You Use It?
Siliconised acrylic sealant is an adhesive widely used in construction and suited to many applications. Its water resistance and flexibility make it ideal for closing cracks, smoothing surfaces and joining materials. Correct application is important for strong, lasting results.

Several points matter when using siliconised acrylic sealant. A clean surface, uniform mixing and appropriate compression help achieve success. This article explains what it is, how to use it and where it is chosen.
What Is Acrylic Sealant?
Knowing what acrylic sealant is matters to correct use. It is a sealing material made from water-based acrylic resins and is unsuitable for direct water exposure. Paintability makes it popular in indoor and outdoor decoration. It hardens after drying and has an environmentally friendly composition. It fills gaps, prevents water leaks and serves decorative purposes. Correct use provides both durability and an attractive finish. Its resistance to seasonal and environmental changes makes it particularly popular in facade coverings and floor applications.
Its functionality and environmentally friendly properties provide a lasting, reliable solution that meets users’ and environmental needs.
Where Is Siliconised Acrylic Sealant Applied?
This construction material resists moisture and both low and high temperatures. It can be applied to different materials indoors and outdoors, generally for sealing cracks and gaps. It is also chosen for expansion joints between prefabricated elements and fitting wood, PVC, iron and aluminium frames. Other uses include plaster joints and connections between fibre-cement or aluminium roofing and facade sheets. This affordable, effective sealant improves durability and appearance. Choosing Selsil siliconised acrylic sealant helps create strong, lasting structures.
How Do You Use Siliconised Sealant?
It is a paintable acrylic filling and insulation material applied with a gun. The surface must be clean, dry and free of dust, dirt and grease. After drying, it remains flexible for a long time and forms a waterproof layer. For Selsil Siliconized Sealant, surface drying takes 15–60 minutes at 23°C and 50% relative humidity. This is different from full cure time. Apply between 5°C and 35°C. Follow the instructions before water contact or painting. It also suits decorative uses such as filling cracks before painting, rather than waterproofing alone.
