Wetwall Alloy Installation Guide FAQs

What surfaces can Wetwall Alloy panels be installed onto?

Wetwall Alloy panels can be fitted onto solid, flat surfaces including plasterboard, existing tiles, plywood, chipboard, and tile backer boards. The wall must be dry, clean, level, and free from damp before installation begins.

Can Wetwall Alloy panels be installed over tiles?

Yes, Wetwall Alloy panels can be installed directly over existing tiles providing the tiled surface is secure, level, and properly degreased before fitting.

What adhesive should be used with Wetwall Alloy panels?

The installation guide recommends using Wilsonart Complete Adhesive and sealants. Using the recommended products helps maintain the Wetwall lifetime guarantee.

Do Wetwall Alloy panels need sealing?

Yes. All joints, edges, fittings, and gaps around shower trays or baths should be fully sealed using the recommended neutral cure sealant to create a waterproof finish.

How much gap should be left above the shower tray or bath?

A 3mm to 4mm expansion gap should be left between the bottom of the panel and the shower tray or bath edge before sealing.

Can Wetwall Alloy panels be cut?

Yes, Wetwall Alloy panels can be cut using suitable fine-tooth blades designed for aluminium or metal cutting. Circular saws, jigsaws, drill bits, and hole saws suitable for aluminium are recommended.

Do Wetwall Alloy panels have a protective film?

Yes, most panels include a protective film on both sides to help prevent damage during transport and installation. This should only be removed during fitting.

Can heavy bathroom fittings be attached through the panels?

Yes, fittings such as shower screens, towel rails, and shower accessories can be fixed through the panels. Heavy items should have solid support behind the panel for secure fixing.

How long should adhesive cure before sealing?

The guide recommends waiting 24 hours for the adhesive to fully cure before applying sealant around the tray, bath, joints, and fittings.

Are Wetwall Alloy panels waterproof?

When installed correctly using the recommended trims, adhesive, and sealant, Wetwall Alloy panels create a waterproof wall covering suitable for showers and bathrooms.

Should I dry fit Wetwall Alloy panels before installation?

Yes, the installation guide strongly recommends carrying out a dry fit before final fixing. This helps check panel alignment, positioning, and trim placement before adhesive is applied.

Do Wetwall Alloy designs match across panel joints?

No, the guide explains that patterns and designs are not intended to match across panel joins, especially on large-scale decorative finishes.
