Why choose pressure treated timber?

Can you paint treated timber?

Yes, you can. Many customers ask, “can you paint treated timber?” The answer is simple – once the wood is fully dry, you can paint or stain it to suit your style. This adds another layer of protection while improving the look of your project.
