Overview

Bostik A325 Acrylic Sealant is a high-quality, versatile sealant designed for interior use. It is based on an acrylic dispersion that cures by water evaporation to form a soft, plasto-elastic rubber. This sealant is paintable with both water-based and synthetic paints, making it ideal for finishing and sealing a wide range of joints and gaps.

Its excellent adhesion and flexibility make it suitable for various substrates, providing durable and neat sealing solutions in construction and renovation projects.

Applications and Typical Usage

• Interior Sealing: Ideal for sealing connection joints between stairs, walls, ceilings, skirtings, and windowsills.
• Frame Sealing: Suitable for wooden and metal window frames, concrete, and brickwork.
• Priming Porous Surfaces: Porous substrates like gypsum or aerated concrete should be primed with a diluted mixture of Bostik A325 before application.

Technical Notes

Substrates must be solid, clean, dry, and free from grease or dust to ensure optimal adhesion. For porous surfaces, priming with a mixture of one part Bostik A325 and two parts water is recommended to improve bonding. The sealant cures by water evaporation, forming a durable, flexible rubber that maintains its elasticity over time.

Application temperature should ideally be between 5°C and 40°C. The product is designed for interior use only and should be protected from moisture until fully cured. Drying time varies depending on joint size and environmental conditions but typically completes within 24 hours.
