Interlocking Wall Panels: Installation

It is Simple!

A: The panels simply fix together in a similar way to tongue and groove wood planking.

B: Panels can be glued directly to existing sound surfaces, including tiles, using a variety of building adhesives, or can be fixed mechanically (nailed, screwed or stapled) to firring strips on uneven surfaces.

Panels are 3/16"- 3/8" thickness with hollow honeycomb section core, manufactured from PVC.

Various lengths are available although the 8-ft length is the most common.  The majority of the  panels are 10" wide,  and some panels are available in other widths. Panels lock together with a tongue and groove system. The surface of panels have been decorated using a printing process, and are not designed to resist scratching. Heavy impact may result in crushing of panels. A range of trims are available in various colors.
Plank Panels can vary in length and thickness. Visit product pages for more details.
The panels are designed for covering internal walls or ceilings in any room in the home or commercial space, but they are specifically conceived for wet environments such as bathrooms, showers, kitchens or utility rooms.

The most common applications for Plastic Panels:

Showers /Bathrooms / Basements and Laundry rooms / Garage ceilings and walls / Wainscoting / Food, Meat processing plants / Dairy, Hog and Poultry buildings / Restaurant kitchen and bathrooms / Day and Health care facilities / Schools, Gyms / Public bathrooms / Trailers & RVs / Car washes / Kennels / Marinas
Polyurethane (PU) Adhesive and an applicator gun
Measuring tape
Masking tape
Electric drill for installation of fixtures
Spirit level or plumb line
Electric jig saw, or hand held saw (15 teeth per inch or more), or junior hacksaw.
Notched adhesive comb spreader
Silicone sealant (for waterproofing joints, edges, and corners in wet areas)
Craft knife

a. Use the panel for indoor uses only.

b. The background must be sound, dry and in good condition.

c. When using the panels in high pressure shower areas, use silicon sealant in the groove on the back of the lip for a water-tight seal.

d. Before fitting panels around sources of heat, for example radiators or fire places, make sure the temperature level doesn't exceed allowed level of 140F (60C).
The panels can be cut horizontally or vertically using simple woodworking tools. Panels can be easily cut or trimmed using a hand saw, table saw, portable circular saw, jig saw or sharp utility knife. The finer the teeth, the neater the cut you will achieve. We also recommend using Dremel Multi-Max.

Panels are normally fitted running from floor to ceiling (tongue and groove running vertically), although it is also possible to fit with tongue and groove running horizontally.

Due to the tongue and groove nature of the paneling, they can be fixed through the tongue, meaning that fixings are always hidden.
In the majority of the cases there is virtually no preparation needed - the panels can go straight onto brick, cement block, plaster, timber battens or stud-work and can even go over existing ceramic tiles.
If the surface is very uneven, wooden firring can be used to achieve a level surface and then the panels can be attached to the firring. We would recommend you start by placing firring approx. every 12 - 16 inches. To install the panels vertically, place the firring horizontally and vice versa. In rooms with a high humidity treated wood and stainless steel fixings should be used. Extra insulation can be installed between the firring strips.
Depending on the type of wall or ceiling you can choose different types of fitting:

Smooth, even walls:
simply glue the panels to the wall (plaster, plaster board, cement, stud work or even to existing ceramic tiles!)

Rough, uneven walls:
use wooden furring strips, and attach the panels to the strips by staples, screws or glue.

Screw fix: Apply screws through the panel lip as shown in the diagrams below. Screw fixing can be made to wood battens. However breeze block, brick or plasterboard will require the wall to be plugged before screwing. When the first plank is fixed in place the next conceals the previous fixing see diagram below.

Stapling: You can use stainless steel staples when fixing to plaster or wood battens - this method is particularly suitable when using battens. Always make sure your battens are flat and level, packing them out where necessary on uneven walls, this will prevent the panels from developing a curvature following the wall contours.

Gluing: This is the method most preferred by many installers however you can only use adhesive when applied to a dry, even wall. The wall must be free of any greasy substances and dust. Only use specialist adhesive. A few options to consider:
Fixing to plaster, brickwork or studs
: use general purpose, solvent based adhesives or neutral cure low modulus silicons.
Fixing to tiling: use a moisture cure, solvent-free adhesive or silicone.

Generally: Liquid Nails Heavy Duty Construction Adhesive (LN-901), Multi-purpose waterproof PL200 construction adhesive. 

Each material you glue the panel on reacts differently. You should consider both factors: the PVC panel AND the surface it's glued upon.
Apart from using trims (see here), both internal and external corners can be neatly done by bending the panels - just carefully cut the back face of the panelsboard along where the corner will be and shape the panel into the internal or external curve

Ceiling panels can be run in either direction; You should consider both directions as one way is likely to need less material than the other.Of course, you may have a preference as to which way you would like run the panels for visual effect.

Use the same installation technique when fitting panels onto the ceilings - apply adhesive to an existing ceiling or wood furring strips and fix the panel with screws to hold it in place.

If wide temperature fluctuation exists in the area of decorative wall panel installation, over-sized holes for screws are recommended. Also, allow expansion and contraction gaps between panel ends and moldings. When fitting halogen ceiling lights there needs to be a 3/8" gap between the halogen bulb and the panel.

Interlocking Plank panels are easy to install. Provided the wall surface is completely flat, you may glue/silicone the panels to the wall. (PL200 is recommended) If not you can either staple, nail or screw the boards on furring strips. In rooms with a high humidity treated wood and stainless steel fixings should be used. Extra insulation can be installed between the strips. 


1. In case you decide not to glue the panels to the wall, you start by placing furring strips app. every 12”-16”. To install the panels vertically, place the battens horizontally and vice versa. 

2. Continue by measuring the number of panels you will need for the wall or ceiling. If the last panel is too narrow, we advise to saw the first panel so that you have at least 1.5” on either side. 
Panels can be cut using the following methods: 
Table Saw with a fine tooth saw blade (such as a fine tooth plywood saw blade). 
Powered Miter Saw with a fine toothed saw blade 
Hand saw 
CAUTION: Take appropriate precautions when using any cutting tools. 

3. If using the trims; start by fixing the end cup trim around the surface you want to decorate. Insert the first panel into the trim. Make sure the first panel is placed perfectly straight (using a spirit-level or a thread with weight) before stapling, nailing or screwing the lip onto the furring strip. Leave about 0.2” clearance between the panel and the edge trim. A fine tooth saw is recommended for cutting the panels to size. 

4. Insert the second panel completely into the groove before stapling (nailing or screwing) into the lip. Proceed in the same way with the next panels. For the finish you can also use the internal corner profile, the external corner; and/or the centre joint. 

5. Perfect finishing: Our high quality PVC decorative panels can be bend easily to make interior and exterior corners. You can cut off the part of the panel and shape it into external or internal curve. This way you can achieve an ideal finishing.


Once the panels are installed there might be other items that you need to fix to the walls, such as soap dishes, shower curtain rails, etc. For lightweight items you can fix directly to the panels using plaster plugs or through the panel into the wall. For larger or heavier items you it is recommended that you fix wood battens behind panels where accessories are to be fixed. Use of spacers between the wall and the surface of the fixed panels is also recommended when fitting heavy items.

Fixing heavy/large items: Detailed Instructions
Decorative plastic panels are designed to maintain its initial color and finish for decades. However typical use and exposure to natural indoor and outdoor elements may result in accumulation of dust or any other materials, therefore owner might want to take some additional steps to maintain an original look of the panels.
Here are our basic suggestions.
Temperature: Use the product in temperatures between -4F (-20C) and 140F (+60C).
Cleaning: Panels can be cleaned with a soft cloth and the use of regular non-abrasive domestic cleansing products. Do not use solvents or solvent containing products.
Mildew removal: Mold and mildew may accumulate on you paneling system when exposed to extremely damp weather conditions. Mold and mildew are not grow on PVC, but might feed on materials that settle on paneling surface. Regular cleaning of the panels will reduce the source of the mold.

The finish of the job is critical to the overall look of the project,take particular care at corners and edges.
The decorative face of the panels is vulnerable to scratching - take particular care during installation
Always cut and drill with the decorative side of the panel face up.
Allow panels to reach room temperature for 3/4 hrs prior to installation.
Surfaces must be free from dirt, waxes or any other residues.
Apply adhesive thinly and evenly directly to the wall and spread using a spreader comb.
Always wear safety glasses when cutting.
When fixing trim with adhesive try to avoid getting adhesive on the decorative face of the panels.
To waterproof joints use a little silicone in the groove of the tongue and groove, don’t apply too much or this will spill out onto the decorative face of the panels.
For the best finish at the bottom, remove any existing skirting, run panels down to the floor and replace with new skirting. Panels can be crushed under load, do not overtighten screws when surface mounting shower heads or other such items.

Allow for a 0.1" gap at the edges of the panels, this is to allow for expansion.
This is particularly important in showers where there is a large temperature variation.

Use of Liquid Nail Products: The best product for this application is Liquid Nails Heavy Duty Construction Adhesive (LN-901). In VOC compliant states it is packaged under product number LN-903. Mechanical fasteners should also be used if possible. Mechanical fasteners and adhesive together will give you the best possible bond. You want to make sure both surfaces are clean, dull and dry before adhering them together. For more information, call Liquid Nails Adhesive at:1-800-634-0015
Think about where you want to install your wall panels. Addressing questions about usage, placement and other concerns will help you to choose the right kind of wall coverings, and also help you to decide on wall covering plans.
Panels are normally placed vertically i.e. from floor to ceiling. Panels may also be fitted horizontally if the shape of the room makes this an easier option.

To find out how many panels you require ( vertically placed panels):
1. Measure each wall length and height.
2. Divide each wall length measurement by the panel width.
3. Round up any fractions to give the number of panels required for that wall.

All panels are only available in pack quantities, so you need to round up to the nearest multiple of the pack quantity. For your convenience, you could also use the panel quantity calculator located below every panel description. This will give you an estimation of how many panels you require. To get an exact figure you will need to plan where each panel will be placed. Doors and windows are worth to consider. Of course only the part above the door needs to be covered. The same consideration can be given to any areas where a much less than a full length panels is required, but remember that it is always wise to allow extra for wastage and cutting errors.

Wall Height: The majority of the panels are 8ft high so if your room is slightly more than that you can use skirting or cornices to make up the difference. You will need to plan where each panel will be placed. The same consideration as above can be given to any areas where a much less than a full length panels is required, but remember that you should make some allowance for cutting mistakes, and that materials needed should be rounded up to full packs regardless.

Ceilings: PVC interior wall panels can be run in either direction; You should consider both directions as one way is likely to need less material than the other. Of course, you may have a preference as to which way you would like run the panels for visual effect.

It is always wise to allow extra for wastage and cutting errors. This usually adds up to about 5-10% of your square footage, according to your skill level. Better to have a bit extra than to run out of product.
