Bona R777 2K PU Parquet Adhesive: For Strong and Durable Parquet Floors

What is Bona R777 2K PU Parquet Adhesive?

Bona R777 2K PU Parquet Adhesive is a high-quality two-component polyurethane adhesive for parquet that complies with EN ISO 17178 (hard). This adhesive contains no water or organic solvents and cures through a chemical reaction without shrinking. Bona R777 is particularly suitable for wood species that are highly sensitive to swelling due to moisture and for substrates that are little to non-absorbent. It offers excellent adhesion to virtually all substrates and wood materials, with a firm texture that retains the trowel pattern. This makes the adhesive ideal for a wide range of parquet and wooden floors.

How Bona R777 2K PU Parquet Adhesive Works

Bona R777 2K PU Parquet Adhesive works through a chemical reaction that begins when the two components, resin and hardener, are mixed together. The mixture has a pot life of about 50 minutes at 20°C and 55% relative humidity. During this time, the adhesive should be applied with a suitable notched trowel. The open time of the adhesive is about 120 minutes, meaning the parquet must be laid and pressed firmly within this timeframe. The adhesive fully dries in about 24 hours, after which the floor is ready for further finishing. Bona R777 provides a lasting bond that withstands intensive use without the risk of swelling or deformation of the wood.

Benefits and Features

The Bona R777 2K PU Parquet Adhesive offers numerous benefits for both professionals and DIY enthusiasts. It is a water- and solvent-free adhesive, which minimizes the risk of wood swelling. The adhesive provides excellent adhesion on both absorbent and non-absorbent substrates and maintains its texture even when using a notched trowel. The product is easy to apply and does not require a primer on most substrates. Bona R777 is compatible with various types of parquet, from mosaic parquet to solid wood and multilayer parquet, and can also be used on difficult substrates such as asphalt and metal.

Instructions for Use

To apply Bona R777 2K PU Parquet Adhesive, the substrates must be clean, dry, crack-free, and slightly rough. Fully mix component B (hardener) with component A (resin) until a uniform color is achieved. Then, evenly apply the mixed adhesive with a notched trowel that matches the type of parquet being installed. Ensure the adhesive is used within the pot life of 50 minutes and the parquet is placed within the open time of 120 minutes. After laying the parquet, the floor should remain unladen for 24 hours to ensure complete curing.

Maintenance or Advice

When using Bona R777 2K PU Parquet Adhesive, it is important to maintain an optimal climate: air temperature of at least 18°C, floor temperature of at least 15°C, and relative humidity of up to 70%. The adhesive should be stored at temperatures between +10°C and +25°C in a dry, well-ventilated area. For the best results, always consult the technical data and safety sheets and ensure that all manufacturer’s application guidelines are followed.
