Full Spread Glue Installation

The full spread glue-down installation method is an ideal choice for engineered hardwood flooring, particularly when installing over concrete subfloors, as often found in condominiums and apartment buildings. This technique offers a sturdy, permanent solution for flooring installation, essential in multi-story buildings where stability and sound reduction are key considerations. Here’s an overview of the process:

1. Preparation of Subfloor: The concrete subfloor must be thoroughly prepared before installation. It should be clean, dry, and level. Any cracks or irregularities in the concrete need to be repaired. Moisture testing is crucial in these settings to ensure the concrete is not too damp, as excessive moisture can damage the wood over time.
2. Acclimatization of the Flooring: Similar to other installation methods, the engineered hardwood should be acclimatized to the room’s environment. This step is critical to prevent the wood from expanding or contracting post-installation due to changes in temperature and humidity.
3. Selection of Adhesive: A high-quality adhesive suitable for wood flooring and concrete subfloors is essential. The adhesive should also have moisture barrier properties if the concrete subfloor has higher moisture levels.
4. Applying the Adhesive: The full spread glue-down method involves applying a uniform layer of adhesive over the concrete subfloor using a notched trowel. The size of the trowel notch should be chosen based on the manufacturer’s recommendations to ensure optimal adhesive spread.
5. Laying the Planks: Engineered hardwood planks are carefully laid onto the wet adhesive, ensuring each plank is firmly pressed down for a secure bond. The planks should be installed in a staggered pattern to enhance floor stability and aesthetic appeal.
6. Adhesive Curing Time: After laying the planks, it’s important to allow sufficient time for the adhesive to cure fully. During this period, foot traffic on the floor should be minimized.
7. Finishing Touches: Once the adhesive has cured, finishing touches like installing baseboards or trim can be completed. These not only enhance the floor’s appearance but also cover the expansion gap left around the room’s perimeter.
8. Post-Installation Care: Care instructions, especially in the initial days post-installation, include avoiding heavy furniture placement and maintaining a stable room temperature and humidity level.

The full spread glue-down method provides a robust and lasting installation, ideal for concrete subfloors in condos and apartments. It ensures a quiet, stable, and durable flooring solution, making it a popular choice in multi-story residential buildings.
