CONCRETE, traditionally used for warehouse and factory flooring, has become a flooring trend.  When concrete is used for flooring it is important to remember that it expands and contracts, due to changes in thermal conditions, and expansion joints must be catered for.

An expansion joint with a polyurethane sealant, such as Den Braven Hybrilfex-540, a one-component moisture curing sealant, will reduce cracking between slabs. Important guidelines and equations for expansion joints are available on the Den Braven website:

Hybriflex-540 is typically used with polyethylene backing cord or rod as a bond breaker in concrete joints to create the right joint dimensions for the sealant to be applied, and to avoid three-sided adhesion.

Other areas Hybrilfex-540 can be used on are walkways and pavements, sealing concrete barriers and culverts. In addition it can be used on floor tiles, laminate and composite flooring, skirtings and kick plates.

When it comes to filling, sealing and joining laminates, parquet, cork and wooden floors Den Braven Woodflex is ideal. It can be sanded and painted and is available in six different wood colours.

Den Braven Fix-O-Chem is perfect for fixing balustrades, safety barriers, banisters and hinges. It can also be used for fixing down dynamic machinery in factories, base plates and a multitude of other applications into masonry, concrete, rock and stone.

Fix-O-Chem is immediately ready for use with a high bond strength. It has good thermal and mechanical properties with extremely low shrinkage (due to hardening) and is suitable for indoor and outdoor use. It can be used for vertical and horizontal fixing applications and instead of plugs or expansion anchors to offer longer lasting secure fixings. Unlike expansion anchors, it does not have any pressure build up on the edge of substrates.

Fix-O-Chem has a self-mix nozzle for convenience and is applied with a standard cartridge applicator.
