High moisture-resistant, water-based PVA adhesive for interior and exterior woodworking applications. Fortis AD317 provides strong, durable bonds to hardwood, softwood and engineered timber and meets DIN EN 204/D3 requirements.
Information | Applications | Specifications | Downloads | FAQs
Fortis AD317 is a high-quality, water-based PVA adhesive designed for interior and exterior woodworking applications requiring excellent moisture resistance and strong, durable bonds.
Meeting DIN EN 204/D3 requirements, AD317 is suitable for timber bonding applications exposed to high humidity or occasional moisture. It provides excellent adhesion to hardwood, softwood and engineered timber products and dries clear for a clean finished appearance.
AD317 is particularly suited to furniture manufacturing, cabinet making, joinery and general woodworking. Its high-solids formulation provides good bond strength while remaining easy to apply using conventional woodworking methods.
The adhesive is water-based and non-toxic, making it suitable for professional manufacturing, workshop and general woodworking applications.
AD317 is intended for non-structural bonding. For structural timber applications, contact Fortis Adhesives & Coatings for advice on the appropriate adhesive system.

Ensure all bonding surfaces are clean, dry and free from dust, oil, grease and other contaminants that may interfere with adhesion.
For optimum results, timber should have a moisture content of approximately 8–10%. Apply Fortis AD317 evenly to the bonding surface using suitable woodworking application equipment.
Bring the components together within the recommended open time and apply sufficient clamping pressure to achieve close and even contact across the complete bonded area.
For best results, joints should be accurately machined and provide close wood-to-wood contact. Excess adhesive should be removed before it fully dries.
Do not apply AD317 below 10°C. Recommended relative humidity during application is approximately 60–70%.
Allow bonded components to remain clamped for the period specified in the current Technical Data Sheet. Full bond strength develops within approximately 24 hours under suitable conditions.
AD317 is intended for non-structural applications. For structural timber bonding, contact Fortis Adhesives & Coatings for advice on the appropriate adhesive system.
Suitable substrates include:
• Hardwood
• Softwood
• Solid timber
• MDF
• Particleboard
• Plywood
• Engineered wood products
• Timber veneers
• Other porous wood-based materials
Bonding surfaces must be clean, dry and free from dust, oil, grease and other contaminants that may interfere with adhesion.
For optimum bond strength, joints should be tight fitting with excellent wood-to-wood contact. A joint gap of less than 0.3 mm is recommended.
Timber surfaces should be accurately machined and smooth. Planing or similar preparation methods can improve surface contact and help achieve consistent bond strength.
Where AD317 is used for suitable finger-jointing applications, accurate machining and a good mechanical fit are essential.
Always test adhesion and processing conditions before production use, particularly when bonding engineered or treated timber products.

What is Fortis AD317 used for?
Fortis AD317 is a moisture-resistant PVA adhesive for bonding hardwood, softwood, engineered timber and other wood products in interior and exterior woodworking applications.
Is AD317 suitable for exterior use?
Yes. AD317 meets DIN EN 204/D3 requirements and is suitable for appropriate exterior applications exposed to occasional moisture. It is not intended for continuous water immersion.
Is AD317 waterproof?
AD317 is a D3 moisture-resistant adhesive rather than a permanently waterproof adhesive. Always select the adhesive according to the expected service conditions.
What does D3 PVA mean?
D3 is a moisture-resistance classification under DIN EN 204 for thermoplastic wood adhesives. It allows use in specified interior applications with frequent short-term water exposure and suitable exterior applications protected from direct weather.
Can AD317 be used on hardwood?
Yes. AD317 provides excellent adhesion to correctly prepared hardwood and softwood.
Can AD317 be used for MDF and plywood?
Yes. It is suitable for many engineered wood products including MDF, plywood and particleboard.
Does AD317 dry clear?
Yes. AD317 dries clear.
Is AD317 suitable for structural timber?
No. AD317 is intended for non-structural bonding. Contact Fortis for advice where a structural timber adhesive is required.
What temperature should AD317 be applied at?
Do not apply AD317 below 10°C. Refer to the current TDS for complete application requirements.
