Identify the exact panel system
PVC identifies a material family, not a universal wall-panel specification. Products can differ in thickness, profile, surface finish, joint design and accessories. Ask for a product code and cross-section so you can see what is behind the decorative face.
Dumaplast presents several distinct interior PVC cladding ranges with different formats. This illustrates the need to compare named systems, rather than assuming every panel sold as PVC behaves alike.
Match the product to the location
Describe the wall exposure accurately: a dry television wall, a kitchen splash area and a shower are not the same application. Obtain confirmation of where the chosen product and complete jointing system may be used.
A claim about the panel’s resistance to water does not diagnose a damp substrate or confirm that corners, penetrations and joints form an appropriate finished assembly. Ask who addresses the existing wall condition and any waterproofing requirement.
Review joints and edge details
Inspect a joined sample, not just one panel. Review visible seams, corners, end trims and cut edges. Confirm how the design will meet doors, sockets, ceilings and skirting. Ask whether the proposed finish changes the wall depth around existing fittings.
If a marble-look or tile-look design repeats, examine multiple pieces together. Agree the layout and batch before purchase so the pattern is deliberate rather than an installation-day decision.
Get a written fixing proposal
The manufacturer’s instructions should identify appropriate substrates, fixing methods and accessories. Ask what preparation is included if the existing paint is loose or the wall uneven. Do not use the panel facing as the assumed support for heavy fixtures.
Request documentation for any performance requirement, including fire or specialist cleaning needs, for the exact product and assembly. Keep the documents with the quote so substitutions can be reviewed before work begins.

COMMON QUESTIONS
Frequently asked questions
Are all PVC wall panels interchangeable?
No. Products can differ in construction, joints, formats and accessories. Compare the exact systems and their installation instructions.
Does a water-resistant panel prove the entire wall is waterproof?
It does not establish the condition of the substrate or the performance of every joint and penetration. Confirm the complete proposed assembly and any separate waterproofing scope.
Can panels be fixed over loose existing paint?
Ask the installer to assess and prepare the substrate under the selected system’s instructions. Covering an unsound coating does not make it a suitable fixing surface.
