GETTING THE SYSTEM RIGHT

Why installation accessories matter.

Rigid PVC wall cladding provides a smooth, durable and cleanable finish when specified and fitted correctly. However, the sheets are only one part of the installation. Suitable adhesives, joining profiles, corner details and finishing products all contribute to the completed wall system.

The adhesive must be compatible with both the PVC and the supporting surface. Incorrect products or application methods can result in unreliable bonding, uneven support or damage to the cladding. In the same way, poorly selected joining and edge profiles can compromise the appearance and maintenance of the finished wall.

This is especially important in commercial kitchens, food preparation facilities and hygienic environments, where joints and corners must allow effective cleaning. Wet areas also require an assessment of sealing and waterproofing requirements.

This guide explains common accessory types and how they are typically used. The final specification should always follow the instructions for the chosen cladding system.

BONDING MATERIALS

Choosing the correct PVC cladding adhesive.

Different adhesive technologies are used for rigid PVC wall sheets. Selection depends on the substrate, sheet specifications and installation conditions.

OPTION 01 / POLYURETHANE
PU

Polyurethane Adhesive

Polyurethane adhesive is used in some rigid PVC wall cladding systems and may be supplied in larger tubs for spreading over prepared wall surfaces. The specified application method, coverage and curing conditions depend on the product.

Certain systems use approximately 6.5kg of adhesive per full-size sheet as a planning allowance, but this is not a universal rate. Always use the actual adhesive manufacturer's guidance.

Check before use Adhesive approval, substrate preparation, spreading pattern and coverage.
OPTION 02 / MS POLYMER
MS

MS Polymer Adhesive

MS polymer adhesives are available in cartridge formats and are specified for certain PVC cladding installations. They can offer an alternative application method where the product and system permit cartridge bonding.

Depending on the sheet size and approved adhesive application pattern, some cladding systems use approximately three or four cartridges per sheet. Cartridge volume and product coverage must be verified before ordering.

Check before use Cartridge capacity, bead pattern, adhesive compatibility and cure time.
!
Do not substitute adhesives without approval.

A general-purpose construction adhesive is not automatically suitable for rigid PVC wall cladding. Verify compatibility with the sheet, substrate and operating environment.

QUANTITY PLANNING

How much adhesive will you need?

Start with the sheet dimensions and the manufacturer's specified application rate. The example below demonstrates how different quantities affect a project.

Number of sheets PU at 6.5kg per sheet* MS at 3 cartridges* MS at 4 cartridges*
1 sheet6.5kg3 cartridges4 cartridges
5 sheets32.5kg15 cartridges20 cartridges
10 sheets65kg30 cartridges40 cartridges
20 sheets130kg60 cartridges80 cartridges

*Illustrative planning assumptions only, based on example usage rates for particular cladding systems. Actual coverage may vary significantly. These figures are not manufacturer-approved recommendations and do not account for all sheet formats or installation conditions.

What changes adhesive consumption?

Substrate flatness, porosity, sheet dimensions, the type of adhesive and the approved fixing pattern all affect how much adhesive may be required. Some systems call for a full-area spread, while others use an approved bead arrangement. These methods should not be interchanged without technical approval.

When planning quantities, calculate the adhesive requirement for the actual number of sheets and include any reasonable allowance permitted by the manufacturer. Do not attempt to compensate for an unsuitable wall surface simply by adding more adhesive.

PLANNING FORMULA
Sheets required × Approved adhesive allowance = Total adhesive quantity

Round up to whole packs or cartridges and confirm their actual sizes before ordering.

JOINING & FINISHING

Understanding PVC cladding trims.

Different profiles serve different purposes. The correct trim depends on sheet thickness, wall layout and the specified joining method.

H
PROFILE 01

H Joining Profile

H profiles are commonly used to connect adjacent PVC sheets and provide a defined joint between panels. Select a profile compatible with the sheet thickness, movement allowance and finishing method.

J
PROFILE 02

J Edge Profile

J profiles are often used around exposed sheet edges and terminations, creating a more finished appearance. The precise use depends on the profile design and manufacturer installation guidance.

F
PROFILE 03

F Finishing Profile

F profiles can provide particular edge finishing and transition details. Their configuration varies between product ranges, so confirm the intended use and the dimensions before ordering.

∟
PROFILE 04

Corner & Angle Trims

Internal and external corner components help finish wall junctions. Depending on the system, rigid angles or specialist corner profiles may be specified to complete the installation.

Profile type Common purpose What to check
H profile Joining adjacent sheets Sheet thickness and joint allowance
J profile Exposed edge finishing Profile opening and fixing method
F profile Selected edge and transition details Profile geometry and intended application
Corner / angle Finishing internal or external corners Corner shape, substrate and compatibility
Coving Creating specified coved transitions Hygiene, sealing and installation requirements

Profile designs and terminology can differ between manufacturers. The descriptions above are general rather than universal.

FINISHING THE INSTALLATION

Corners, coving and sealants.

The finishing details can be particularly important where moisture resistance and regular cleaning are required.

01 / CORNERS

Internal & External Corners

Corner details complete the transition between adjoining wall surfaces. In hygiene-sensitive environments, corners should be appropriately finished so that cleaning can be carried out effectively.

Check whether the cladding system specifies corner profiles, formed sheet details or a particular approved jointing method.

02 / COVING

Coved Wall Junctions

Coving provides a shaped transition at selected wall junctions. It is used in some hygienic installations where a conventional sharp corner may be more difficult to clean.

The need for coving depends on the premises specification and the complete wall or floor system being installed.

03 / SEALING

Compatible Sealants

Suitable sealants may be required around penetrations, joints and selected edges. Sealant selection should consider adhesion, movement, moisture and chemical exposure.

Sealant must not be used as a substitute for incorrect joint design or necessary waterproofing behind the finished wall.

PROJECT PLANNING

Calculate your accessories before ordering.

Begin with a measured wall layout, recording sheet positions, internal corners, external corners, doorways, windows and exposed edges. This provides the information needed to estimate joining and finishing lengths.

Profiles are commonly supplied in fixed lengths, such as approximately 2.44m or 3.05m. Check the actual supplier range and calculate the number of lengths needed, allowing for cutting and unavoidable waste.

Keep adhesive quantities separate from profile quantities because they depend on different measurements. The correct order should also account for any primers, sealants or special finishing details required by the system.

INSTALLATION ADVICE

Common accessory mistakes to avoid.

01

Using the wrong adhesive

An adhesive may bond to one surface but not be approved for the complete PVC sheet system. Verify suitability for both surfaces and the environment.

02

Ordering incorrect profile sizes

Joining and edge trims must match the sheet thickness and required fitting detail. Check dimensions rather than relying on appearance.

03

Underestimating adhesive quantities

Project delays can arise when coverage is calculated from an unsuitable assumption. Use the actual product coverage specification.

04

Ignoring joint movement

PVC responds to temperature changes. Joints and edge details must follow the movement allowances specified by the cladding manufacturer.
