LIGNAU TREP – 2K Stair Tread Adhesive (3.5 kg)
LIGNAU TREP is a professional two-component polyurethane adhesive developed specifically for bonding stair treads, risers, and solid wood elements. The system consists of Component A (base adhesive) and Component B (hardener), which together create a high-strength, flexible bond ideal for demanding wood installations.
The adhesive provides exceptional durability, elasticity, and moisture resistance, ensuring a stable, long-term connection between wood and substrate. It is suitable for solid wood, engineered wood, and composite materials, both in residential and commercial interiors.
Once mixed, the adhesive cures to form a highly resilient elastic layer, absorbing vibrations and preventing creaking — perfect for stair installations and heavy-use areas.
Key Features
- 2-component polyurethane system – professional-grade strength and flexibility
- Strong adhesion for solid wood, engineered wood, MDF, and concrete substrates
- Elastic and vibration-resistant – ideal for stairs and step bonding
- Moisture-resistant and solvent-free – suitable for indoor environments
- Fast-curing formula for efficient installation
Application
Mix Component A and B thoroughly according to the specified ratio before use. Apply the adhesive evenly to clean, dry, and dust-free surfaces using a notched trowel or spatula.
Position the stair tread or panel, press firmly, and allow to cure fully before load-bearing use.

CARBO TREP is a flexible, solvent-free, non-sag 2-component polyurethane reactive adhesive for bonding risers and stair platforms on dry substrates such as concrete, cement, screeds, plaster, metal, gypsum, ceramics, chipboard, wood, and rubber.
It must be ensured that the sub floor is ready for installation by performing proper sub floor preparation, floors must be clean, have sufficient surface strength, must be level, permanently dry and free of cracks. If necessary, make sure sub floors are level, have sufficient absorptive capacity and grip. Then apply adhesive to sub floor, avoid adhesive pooling and excessive layer thickness by evenly raking the notched trowel over adhesive layer. The element to be bonded is then placed on top. Any CARBO TREP adhesive that squeezes out of gaps and seams must be removed immediately. In cold weather, the adhesive should be brought to a warm place in time to reach the proper application temperature. Please test the effect of the cleaner on the finish of the wood flooring in an inconspicuous area or on a sample prior to applying the cleaner. Hardened adhesive residues can easily be removed mechanically, mostly residue-free. However, longer exposures on finished wood flooring should be avoided to prevent possible contouring. After 24–48 hours, the adhesive has hardened to form a tough, permanently elastic, and hydrolysis-resistant bond that absorbs and relieves tension. The curing time is delayed at low temperatures (15 °C).
