Overview

A great wet room installation depends on more than just the panels — it depends on using the right products throughout. The WVH® Waterproof Adhesive & Sealant is a two-in-one formula designed from the ground up to work with the Acupanel® Hydro panel range, handling both the bonding and the sealing in a single, straightforward product.

Whilst the Hydro panel faces are fully waterproof by design, cut edges, the tongue and groove joint between panels, and joins where panels meet adjacent surfaces — such as shower trays, tiles, and wall returns — all need to be properly addressed to prevent water from finding its way behind the installation. The WVH® Waterproof Adhesive & Sealant handles all of this. Apply it to the back of the panel to bond it securely to the substrate, then use it along the tongue and groove edge, at cut edges, and around the perimeter to create a continuous, watertight seal throughout.

The formula is specifically developed for wet and humid environments, so you can install with confidence knowing the bond will hold long-term — even in a daily-use shower. Once cured, it remains flexible to accommodate minor movement and thermal expansion without cracking, and it is mould and mildew resistant to keep your installation looking clean and fresh for the long term.

Unlike general-purpose grab adhesives or bathroom sealants, you don't need two separate products to complete the job. The WVH® Waterproof Adhesive & Sealant is all you need from first panel to finished edge.

Black works well alongside the oak, walnut and grey oak panels, as it blends into the black slat gaps for a seamless finish. The white pairs naturally with the white colourway, blending into the white slat gaps effortlessly. Apply using a standard caulking gun, and smooth sealant beads to a neat finish with a damp finger or smoothing tool.

Installation & Downloads

The WVH® Waterproof Adhesive & Sealant is designed to be used to install the Acupanel® Hydro Waterproof panelling collection. Installing these panels is simple with the tongue and groove edge, which helps create a seamless finish on your walls. The panels can easily be cut down to size and around fixtures and fittings as required. When installing these panels, you will need to apply a sealant along the panel joins as well as the top and bottom of the panels for a watertight finish.

The WVH® Waterproof Adhesive & Sealant can also be used with any of our other interior panelling collections. For further installation guidance, please refer to our technical sheet.

WVH® Waterproof Adhesive & Sealant FAQs

Is the waterproof adhesive product both an adhesive and sealant?

Yes — the WVH® Adhesive & Sealant is a two-in-one formula. Use it to bond the panels to the wall, and then apply it along all tongue and groove edges, cut edges, and panel perimeters to create a continuous waterproof seal. You do not need a separate adhesive and a separate sealant — this product handles both.

How do I use it during installation?

Apply the product to the back of each panel to bond it securely to the substrate, then use it to seal along the tongue and groove joint between panels, around any cut edges, and at the perimeter where the panels meet adjacent surfaces such as shower trays, tiles, and wall returns. Apply sealant beads using a standard caulking gun and smooth to a neat finish with a damp finger or smoothing tool.

Why do I need to seal the tongue and groove edges?

The tongue and groove system creates a neat, seamless join between panels, but there is a small gap at the joint. Applying the WVH® Waterproof Adhesive & Sealant along this edge closes that gap and prevents water and moisture from working their way behind the installation — which is essential for maintaining the waterproof integrity of the finished wall.

Why do I need to seal around cut edges?

When a panel is cut to fit — for example, to accommodate taps, shower fixtures, or other wall penetrations — the cut edge exposes the panel core, which is not waterproof. Sealing thoroughly around all exposed cut edges with the WVH® Waterproof Adhesive & Sealant is essential to prevent moisture from entering behind the panels at those points.

Which colour should I choose?

Black works well alongside the oak, walnut and grey oak panels, as it blends into the black slat gaps for a seamless finish. The white pairs naturally with the white colourway, blending into the white slat gaps effortlessly. As the product is used both behind the panels and at visible joints and edges, choosing a colour that complements your panel will give the neatest overall result.

Can I use a different adhesive or sealant?

Whilst other moisture-resistant grab adhesives and bathroom sealants may be used, we recommend the WVH® Waterproof Adhesive & Sealant as it is specifically formulated for use with these panels in wet environments. Using the recommended product ensures the best bond, the most reliable waterproof seal, and helps maintain the long-term integrity of your installation.

Is the product mould resistant?

Yes — the WVH® Waterproof Adhesive & Sealant is formulated to resist mould and mildew growth at lower levels, as long as the panels are cleaned regularly.

Can I use this product in a steam room or sauna?

The product is formulated for wet and humid environments typical of bathrooms and shower enclosures. For steam rooms or saunas with extreme and sustained heat, please get in touch with our team to discuss suitability before ordering.
