TRADA Technology Ltd has won £70,000 of Department of Trade and Industry funding under the Partners in Innovation programme to evaluate the effectiveness of stain blocking primers for wood joinery.
The project has arisen from the growing problem of discolouration and staining of light-coloured coatings.
TRADA Technology‘s coatings and treatment specialist Peter Kaczmar will head the research. He said: “The movement and subsequent oxidation of naturally occurring compounds within the wood can cause an unsightly disfigurement in the form of dark brown patches in the coating soon after painting.
“Corrective action can be extremely costly, as wholesale remedial measures prior to handover of new buildings are often required, possibly even the complete repainting of all wood joinery.”

There is evidence that the problem is more severe with waterborne coatings, the use of which has risen.
The research results will be published in two guidance documents.
