Installation Instructions:

    1. Prepare the Subfloor: Ensure the subfloor is clean, dry, and free of any debris. Repair any imperfections or irregularities in the subfloor surface.

    2. Unroll the Vapor Barrier: Start at one end of the room and unroll the Visqueen Vapor Barrier Block across the length of the room. Allow the excess material to overlap the walls.

    3. Connect Rows Together: For each subsequent row, unroll the vapor barrier and align it with the previous row, ensuring a snug fit. The pre-attached adhesive tape should be facing up.

    4. Join Rows Together: Peel off the protective backing from the adhesive tape on the first row. Press the adhesive side firmly against the second row to create a secure connection. Repeat this process for all rows, ensuring each seam is tightly sealed.

    5. Seal the Edges: Once all rows are connected, trim any excess material along the edges of the room. Use a utility knife or scissors to cut the vapor barrier to fit.

    6. Secure the Vapor Barrier: To ensure the vapor barrier stays in place, use a heavy object or flooring tools to weigh down the edges and seams temporarily.

    7. Install Flooring: Once the vapor barrier is securely in place, you can proceed with the installation of your flooring material over the vapor barrier according to the manufacturer's instructions.

    8. Final Checks: After the flooring is installed, inspect the seams and edges of the vapor barrier to ensure they are properly sealed. Trim any excess material if necessary.

    9. Enjoy Your Protected Floors: With the Visqueen Vapor Barrier Block properly installed, you can enjoy the benefits of moisture protection for your flooring, ensuring its longevity and durability.
