Product Intelligence
Selleys Liquid Nails VBS Rapid: Technical Specifications and Features
Product Overview
Selleys Liquid Nails VBS Rapid is a highly cross-linked, pigmented, two-pack epoxy water-based vapour barrier system designed for sealing concrete floor slabs and preparing surfaces for timber flooring installation. The mixed product has a distinctive mid-green colour that aids in consistent application.
Primary Application
This product is specifically formulated for sealing concrete floor slabs to reduce the amount of water vapour emanating from concrete surfaces. It is suitable for use on concrete slabs prior to using Selleys Liquid Nails flooring adhesives to lay timber flooring. Water vapour from concrete slabs can affect wooden flooring overlays, and the application of this moisture vapour barrier can help prevent problems with wooden floors from developing at a later stage.
Key Features
- One-coat system: Normally requires only a single application
- Colour-coded components: Resin is white and hardener is green, aiding proper mixing identification
- Controlled opacity: The mid-green pigmented colour of the mixed product helps applicators gauge consistent application rates by eye
- Rapid cure: Enables fast progression to subsequent flooring work
- Very low water vapour transmission rate: Effectively prevents moisture migration
- Low odour and water clean-up: Environmentally friendly formulation
- Excellent adhesion and application properties: Optimal properties for subsequent bonding with Selleys Liquid Nails flooring adhesives

Surface Preparation Requirements
All surfaces must be clean, dry, and sound, free of voids, loose materials, and contaminants including:
- Curing compounds
- Oil and grease
- Waxes and sealers
- Previous coatings or adhesives
Complete removal of any suspected or evident contamination must be carried out. Surface preparation may be achieved by diamond grinding, shot blasting, sand blasting, captive abrasive blast cleaning (Blastrac), or other suitable methods. Diamond grinding is recommended as the best preparation method, enabling removal of high spots and laitance.
Concrete surfaces must be structurally sound, level, and have a finish equivalent to that obtained when using a steel trowel. The product can be applied if the concrete surface is dry and the slab has stabilised. New concrete should be cured for at least 28 days before application.
Dampness Considerations
If dampness is suspected in a concrete slab, verification should be conducted by securely taping a 1 metre × 1 metre square of heavy-duty plastic onto the slab and leaving it for 24 hours. Any visible dampness or discolouration under the patch indicates a warning sign requiring further investigation.
