What is uPVC?

uPVC stands for Unplasticised Poly Vinyl Chloride, which is an energy-efficient plastic often used for window and door frames.


There are many benefits to using uPVC, one, is that it is fire-resistant, giving it an advantage over wooden frames. It is also rigid, which means it will not change shape in the heat of the sun.

In addition to the above structural benefits uPVC is an environmentally safe plastic, more so than polyvinyl chloride (PVC), as it has no hazardous phthalates or Bisphenol A (BPA).

One of the downsides to uPVC is that it’s not biodegradable. However, at very high temperatures it can be remoulded and repurposed, which is therefore recyclable.

Prepare and Prime

No matter what material you are coating, always ensure that you prepare the surface first. To prepare your uPVC surface, simply make sure that it is dry, clean and free of any debris such as mould or dust. 

To achieve a seamless stroke by brush, we recommend sanding the surface before you start. Once the surface has been prepared, degrease the area with methylated spirit and allow it to dry. You can now start priming!

We recommend using eico ican Grepp V Primer.

However, if you are planning on painting with a Gloss or using our recommended paint choice below, you DO NOT need a primer.

Choosing the right paint

Due to uPVC expanding and contracting slightly in heat, you will need a paint that will BOND with the substrate rather than just try to stick to it. We also recommend that you choose a paint that offers UV protection.
