PVC Foam Board Furniture: Edge Sealing Method

PVC Foam board

PVC foam board, also known as PVC foam sheet or PVC foam panel, is a lightweight and versatile material made from polyvinyl chloride (PVC) resin. It is an expanded, closed-cell foam structure with a smooth and flat surface. 

Edge Sealing Methods For PVC Furniture board

Sealing the edges of PVC foam board when used to make furniture is important to protect the edges from moisture, dirt, and mechanical damage.

Normally, two methods are widely uesd for it.

One of the most common methods is to use PVC edge banding tape. This tape is available in various colors and can be matched to the color of your PVC foam board.  It has an adhesive backing that you can apply to the edges.  

Simply trim it to size, peel off the backing, and carefully apply it to the edge, ensuring it is aligned properly.

Second is to lacquer the edge as the follow steps. 

Surface Preparation:

Ensure that the edge of the PVC foam board is clean and free from any dust, dirt, or debris.  If the edge is rough, you can lightly sand it with fine-grit sandpaper to make it smooth.

Apply the First Coat:

Dip a clean, high-quality brush or foam brush into the PVC-compatible lacquer.  Start by applying a thin, even coat of lacquer to the edge of the PVC foam board.  Be careful not to apply too much lacquer, as it can lead to drips and uneven coverage.  Allow this first coat to dry for the time specified on the lacquer's label.

Sand Between Coats:

After the first coat has dried, lightly sand the lacquered edge with fine-grit sandpaper.   This helps smooth any imperfections and provides a key for the next coat to adhere.

Apply Additional Coats:

Apply subsequent coats of lacquer, allowing each coat to dry before applying the next.   The number of coats you apply will depend on the desired level of finish and protection.   Typically, 2-3 coats should suffice, but you can apply more for added durability and shine.

Final Sanding and Buffing:

After the final coat has dried, you can perform a very light sanding using fine-grit sandpaper to remove any imperfections or dust particles.   Be gentle to avoid removing too much of the lacquer.  Then, use a clean, lint-free cloth to buff the lacquered edge to a glossy finish.
