Why is part of the tongue or groove chipped off of the panels? Are my panels defective?
The panels are not defective. During manufacturing, one corner of the overlap lip is intentionally milled off. This is to provide enough space for the four corners to fit together when four panels are connected. The milled tongue or groove does not impact the product performance or finished look.
Is it easy to install DumaWall products yourself?
Yes. DumaWall panels are easy to install by the average do-it-yourself consumer. The panels can be cut to size using a saw (manual or electric) or a utility knife.
On what surfaces can PVC panels be installed?
The panels can be glued to smooth surfaces such as plaster or plasterboard or even to existing tiles. With rough, uneven walls the panels can be affixed to a framework using nails, staples or adhesive. More information about installation methods are included on our installation guide.
What is the maximum temperature for PVC panels?
Our panels can withstand a maximum continuous temperature of 140F. This means that DumaWall PVC panels can be used as a shower wall panel, but cannot be used in saunas. Installation within 6 inches of a stove is not recommended either.
What kind of adhesive and sealant should be used?
When gluing DumaWall products on regular surfaces such as plasterboard or wood, we recommend using Power Grab Ultimate adhesive. For Canadian customers, we recommend Lepage No More Nails Wet Instant Grab adhesive. For DumaWall to be used in wet environments, a bead of sealant must be used in each seam between panels. The sealant we recommend is DAP Kwik Seal Ultra. For Canadian customers, we recommend Kwick Seal Plus.
Should extra silicone be added between panels?
Not normally, however when installing in a wet room (such as a shower, for example), apply a line of silicone sealant to the tongue and groove connection between the panels to ensure a completely waterproof joint. Also apply a line of silicone sealant between the panel and the edge of the shower or bath, and on inside corners.The sealant we recommend is DAP Kwik Seal Ultra. For Canadian customers, Kwick Seal Plus. Be sure to read the sealant or adhesive instructions before use.
How should DumaWall panels be cleaned and cared for?
The panels can be cleaned and polished to their original condition using any typical household, non-abrasive cleaning agent. Normally, you only need a damp cloth to clean the panels thoroughly. Do not use abrasive, aggressive substances or cleaning products based on chloride. We do not recommend using solvents. Adhesive residue or pen marks are best removed using isopropyl alcohol.
Do your products emit toxic fumes? Are your products hazardous when inhaled indoors?
No. Our products are not harmful to your health. All our products are classified as A+ (very low emission of pollutants), which is the best rating for indoor wall cladding. This means you can use our products in your house with no harmful effect on health.
Can I put DumaWall on my ceiling?
Yes. If you choose to apply to a ceiling, you will need to use both the recommended adhesive and mechanical fasteners (nails or staples) to prevent the panels from falling.
Can I use as a working surface and put DumaWall on my floor, use as a countertop, etc?
No. The panels are designed to be used on a vertical wall surface.
Can I paint DumaWall?
Yes, but the panels are not intended to be painted. If desired, consult with your paint department for proper primer and paint for good adhesion.
Do you offer outlet covers/ switch covers?
If I wanted to remove 1 tile (or a few) how would I do so and what would I use?
This can be accomplished and is treated like any other tongue and groove connection. Using a utility knife, cut the tongue of the panel you choose to remove. Once the tongue on both sides is removed, use a putty knife or paint scraper and slide the tool under the panel to be remove and apply outward pressure releasing the adhesive from the wall. You may need to repair the wall after removal if adhesive damages surface to prepare it for new panel.
Do I need to grout DumaWall?
No. Grouting is not necessary as DumaWall already has a manufactured grout line built in.
What if I want to trowel the adhesive on?
You can trowel on the adhesive with a 1/4-inch notch trowel for more even coverage after applying adhesive to the back of the panel or trowel directly onto your wall.
Do I need to seal my basement concrete wall before I install DumaWall?
It depends on the age and surface of your basement wall. In newer homes, the poured concrete walls are traditionally sealed from the outside. In older homes with concrete block foundations, you can seal with a concrete sealer like a Kilz. We do not recommend DumaWall Panels be installed on raw concrete walls. See our installation guide, here.
How do I need to prep my wall before I install DumaWall?
If you choose to install DumaWall on an existing wall, clean it with a good degreaser to make sure the wall is free from any contaminates that would affect adhesion.
Can I put DumaWall in the shower?
Yes, seal all edges with DAP Kwik Seal Ultra sealant at the joint to prevent water infiltration. Apply a line of silicone sealant to the tongue and groove connection between the panels to ensure a completely waterproof joint. Also apply a line of silicone sealant between the panel and the edge of the shower or bath, and on inside corners. The sealant we recommend is DAP Kwik Seal Ultra. Be sure to read the sealant or adhesive instructions before use.
Should I seal the DumaWall for extra protection?
This is not necessary. However, if you are using this in a wet environment such as shower enclosure, we do recommend sealing all edges with a silicone sealer.
How does DumaWall hold up with humidity?
Excellent. The panels are 100% water proof.
Can I put DumaWall outside on my patio (exposed to outside elements/ UV rays)?
No, DumaWall is not exterior-grade-UV-stable.
How do I cut DumaWall?
Standard wood working tools like a table saw or circular saw with a fine tooth provide the best cut edge. Use a 60-tooth blade or higher. Alternatively, you can score one side a few times with a utility knife and snap the tile at the line. This method may require sanding the snapped edges.
Can DumaWall be used in campers, RVs, 4 seasons rooms or garages (non-temperature-controlled areas)?
Yes, as long as the recommended installation methods and adhesives are used leaving 1/4 space at the edges to allow for expansion and contraction.
Are DumaWall panels scratch-resistant?
Yes, there is a durable, UV-cured, protective polyurethane layer on the surface of the panels. This wear- and-scratch-resistant layer will prevent moderate abuse. The tiles are intended as a wall product, however, and can be scratched by sharp objects or dented by blunt force. DumaWall tiles have better wear and scratch resistance than most wall treatments, such as painted drywall or paneling. Panels should be cleaned with household or mild commercial cleaners that do not contain abrasives.

Silicone sealant can also be used instead of trims. Inside corners can be caulked with a matching caulk or you can use clear silicone sealant.
