Coatings Test 2022

I’ve added a couple of new products to the list. Doug Irvine uses the Intergrain Heavy Duty finish on his finger joint boxes so I thought I’d give it a try. I’ve also recently been trying the Weatherfast Poly Clear and it seems quite good.

The best long lasting coating is exterior white paint but the main objective here is to find a decent clear coat that shows off the wood for the longest time before the coating and the wood starts to age and look dull or grey.

All my money is literally on the Intergrain Heavy Duty, because it costs $70 for 4 litres of UltraPrep and $153 for 4 Litres of Heavy Duty.

The previous test was done is 2016 – Link here: https://www.nativebeehives.com/coating-test/
