What is Wainscoting and what do I need to create it?

Wainscoting wall panelling is a decorative wall treatment that comes in a variety of styles. Wainscoting is created using timber mouldings such as inlay mould, chair rail, decorative large skirting boards and sometimes even lining boards, VJ wall panelling and other materials depending on the style of Wainscoting you are looking to create. You can learn about all the different styles and materials required to get the look on our Wainscoting page.

Does my chair rail and architrave thickness need to be the same?

No, however if your chair rail is thicker than your architrave any overhang of the chair rail would need to be champered at a 45 degree angle to finish it.

Do skirting boards have to match the architraves?

Once you have chosen the skirting board the next decision to make is about the architraves. While most people will choose the same profile – in a smaller height – it is possible to mix and match profiles to achieve a look that is both interesting and beautiful. Following are some recommendations that will help in getting the mix right: 1) Architrave widths for different door heights recommendations:
Door Height Architrave Width
2.04m 66-90mm
2.34m 90-135mm
2.70m 115mm+
2) Skirting and architrave combination recommendations:
Skirtings Architrave
90-135mm 66-90mm
115-185mm 90-115mm
185-230mm 90-115mm
230mm+ 115mm+
The most commonly used combinations are:
  • 135mm skirting with 90mm architrave
  • 185mm skirting with 90mm architrave

How much does the mouldings cost?

Our timber mouldings are priced per metre and sold in long lengths. The larger the order on our classic range the lower the price per metre as the machine setup and handling cost are spread over the larger volume. Click the price tab on any individual product page to access the price list.  If you are looking for bespoke custom mouldings, there will be an additional cost. Please call our sales team on 1800 622 081.  

What is the minimum quantity you can order?

The minimum quantity is 1 length. However, we always recommend increasing your order to allow for any wastage or damage. It is the most cost-effective option instead of placing a top-up order if you underestimate your requirements. 

What material is good for external mouldings?

What material is good for external mouldings?  We recommend for using our timber mouldings in external applications that you use either Polyurethane or primed FJ pine. Pine products will require more upkeep, whereas polyurethane provides an excellent alternative to natural timber for external use as it won’t chip, split, and will look good for years without much maintenance. Both are able to be painted with external grade paints following the instructions from the paint manufacturer. 

What paint do you recommend for wet areas?

For wet areas glossy finish is recommended because, unlike Matt which absorbs moisture, glossy paint deflects moisture due to the harder finish. Depending on your choice or requirement of gloss level you can choose from Dulux super enamel semi-gloss or Dulux super enamel high gloss. For the undercoat, we recommend Dulux professional primer sealer undercoat.
