About Bostik Primer N49 Waterproofing Coating

91 000 74051 Bostik N49 Primer is a primer designed for use with the Bostik polyurethane sealant range to ensure adhesion to porous substrates, particularly with water immersed applications. Bostik polyurethane sealants requiring the application of Bostik N49 Primer on porous substrates only are: - Bostik Seal N Flex 1 - Bostik Seal N Flex FC - Bostik Construction PU - Bostik Fireban One

Optimized Surface Preparation

Bostik Primer N49 is specially formulated for porous substrates, such as concrete, masonry, and unglazed tiles. By applying this primer, you create the ideal surface condition for polyurethane sealants, maximizing bond strength and extending the longevity of your sealing project. Its fast-drying and moisture-curing properties help streamline your workflow.

Hassle-Free Application

With its one-component formulation, Bostik Primer N49 requires no mixing-simply apply the liquid directly from the container to your prepared surface. Its quick drying time enables same-day continuation of waterproofing and sealant application, making it highly efficient for construction and industrial projects.

FAQ's of Bostik Primer N49 Waterproofing Coating:

Q: How is Bostik Primer N49 applied to porous substrates?

A: Bostik Primer N49 should be applied as a thin, even coat to clean, dry, and porous surfaces using a clean brush or roller. Allow approximately 15 minutes for the primer to dry before applying polyurethane sealants.

Q: What surfaces are suitable for Bostik Primer N49?

A: This primer is ideal for porous substrates such as concrete, brick, masonry, render, blockwork, and unglazed tiles-commonly encountered in construction and waterproofing contexts.

Q: What is the main benefit of using Bostik Primer N49 before PU sealant application?

A: The main benefit of using Bostik Primer N49 is its ability to significantly enhance the adhesion of polyurethane sealants to porous surfaces, ensuring a stronger, longer-lasting bond and minimizing potential sealant failure.

Q: When should I use Bostik Primer N49 during my sealing project?

A: Apply Bostik Primer N49 after the surface is cleaned and dried but before applying the polyurethane sealant. Wait for the primer to dry (about 15 minutes) to achieve optimal adhesion.

Q: Where can Bostik Primer N49 be used?

A: It can be used in construction, industrial, and maintenance projects wherever there are porous substrates requiring PU sealant application, such as concrete floors, walls, brickwork, and tiled areas.

Q: What makes Bostik Primer N49 different from water-based primers?

A: Unlike water-based primers, Bostik Primer N49 uses a solvent-based, aromatic polyisocyanate formulation (with ethyl acetate), making it suitable for moisture-sensitive curing and ensuring faster drying on porous substrates.
