Reading the following information below will help you understand how to paint & Prepare all surfaces like a pro.


Whether you’re painting your Interior, Exterior or furniture. The surface preparation remains the same.

To get the best adhesion & results from Thermilate Paint, you need to get your surface ready in 3 Short Steps.  

It's critical to achieve perfect results.

Step 1):

If your painting on pre-painted surfaces, Ensure your surfaces are dry, & have been cleaned and if there's any rough patches surfaces must be repaired and sanded. 

(If your painting on fresh plaster please apply a base-coat or a primer before painting, thinning this paint with 50% water will allow a thin layer to be used as a base/mist coat) (use primer on wood & metal surfaces.)

Step 2):

Ensure your wall cracks are filled and repaired to minimise risk of damp.

Step 3):

Ensure your wall or surface is fully dried, dust-free, and condensation-free with no flaking paints.

(NOTE: MOULD, Condensation and Damp problems only grow back when the root issue of the problem is not solved. Mainly caused by bad ventilation & water ingress)

Common Questions:

Should i use a primer before painting?

Can i use this on Wood or metal?
