Polyurethane Adhesives for Timber & Construction

Products: Fortis AD512, Fortis AD5113, Fortis AD5105, Fortis AD5205, Fortis AD5405.

Choose a polyurethane adhesive by substrate, application method and required working time. Use a fast grade for small assemblies, a medium grade for general woodworking, or a long-open-time grade for large and complex components. Flooring, tactile and panel-lamination applications require products designed for those specific processes.

Fortis manufactures polyurethane adhesives in Australia for timber, flooring, construction, composite panels and industrial assembly.

Choose the Right Working Time

For timber assembly, Fortis AD5105 provides a 10-minute working time for fast production. Fortis AD5205 provides a balanced 20-minute working time for general woodworking and construction. For large or complex assemblies, Fortis AD5405 provides an extended 60-minute working time.

Flooring, Construction and Lamination

Fortis AD512 is designed for timber flooring, traffic tactiles, rubber underlay and general construction bonding. It offers strong wet grab across suitable porous and non-porous substrates.

Fortis AD5113 is a low-viscosity adhesive for composite and sandwich panels, stainless-steel benchtops, insulated panels, caravan and transport bodies. Apply it by spray, roller or brush.

Bonding and Preparation

Depending on the grade, these adhesives can bond timber, plywood, MDF, concrete, brick, fibre cement, selected metals, polystyrene foam, rubber, FRP and other compatible materials.

Surfaces must be clean, sound and free from dust, oil and grease. Moisture-curing products require suitable moisture and firm contact during cure. Clamp, weight or support components as directed. Review the Technical Data Sheet and test unfamiliar substrates before production.

Polyurethane Adhesive FAQs

How do I choose a polyurethane adhesive?

Choose according to the materials, application method and required working time. Fortis offers fast, medium and long-working-time timber adhesives, plus dedicated products for flooring, tactiles and industrial lamination.

What is the difference between AD5105, AD5205 and AD5405?

AD5105 provides a 10-minute working time for fast timber assembly. AD5205 provides a balanced 20-minute working time for general woodworking and construction. AD5405 provides 60 minutes for large bonding areas and complex assemblies.

Which polyurethane adhesive is suitable for flooring and tactiles?

Fortis AD512 is designed for timber flooring, rubber underlay, traffic tactiles and general construction bonding. It provides strong wet grab and can be applied by bead or notched trowel.

Which adhesive is suitable for composite panel lamination?

Fortis AD5113 is designed for composite panels, sandwich panels, stainless-steel benchtops and transport manufacturing. Its low viscosity allows spray, roller or brush application.

Do polyurethane adhesives require moisture to cure?

The Fortis products on this page are single-component moisture-curing polyurethane adhesives. Moisture comes from the substrate or atmosphere. Very dry materials may require light misting as directed by the Technical Data Sheet.

What materials can polyurethane adhesives bond?

Depending on the product, suitable materials may include timber, plywood, MDF, concrete, fibre cement, selected metals, polystyrene foam, rubber, fibreglass and composites. Test unfamiliar or coated surfaces before production.
