Can You Paint Over Spray Foam Insulation?

Spray Foam News


Spray foam insulation offers homeowners a range of fantastic benefits, including reduced heat loss, sound proofing properties and a completely non-toxic formula. However, it does have quite a distinct light beige colour that some homeowners might want to hide if it is visible. There are certainly ways around that – by using paint!

You can paint over spray foam insulation, however it is not a hugely straightforward process. Whilst painting is a beneficial method to improve the appearance of foam insulation that is not concealed by drywall, there are steps that must be taken to ensure it is done right.

  • Wait 24 hours

It is very important to wait until spray foam insulation has fully dried before painting over it. This could impact the overall effectiveness of your insulation and could damage the foam. We recommend waiting at least 24 hours post-installation before you paint over it, but the longer the better.

  • Sand the foam

Icynene spray foam insulation can be left with a slightly bumpy, uneven texture, which isn’t ideal for paint. Before beginning the painting process, sand down the top layer of the spray foam. Don’t forget to wear protective eyewear.

  • Spray paint is recommended

If you are researching ‘can you paint over expanding foam’ because you are planning on painting over expanding foam in your home, using spray paint is a favourable option. This is because it takes far less time compared to painting over it with a usual bristle brush or roller. It is also beneficial because it is much gentler on the spray foam. A bristle brush or roller can be used, although it works best with closed cell foam insulation due to its denser texture.

  • Use a professional

We always recommend using a professional painter. This isn’t to limit any damage to your spray foam insulation, but to ensure you get the very best result possible. A few coats are normally required for a strong, opaque finish.
