Hi
During the summer I built several large planters using 45x95 Celcure treated timber. The lengths remained outside for two months in full sun before being used so they were thoroughly dry albeit they were dry when delivered.
Once built they were treated with two coats of Cuprinol seagrass garden shades.
Now a slight green discolouring haze has appeared on the surface of the timbers (as if it were mold) which I can only assume is the Celcure bleeding through the Cuprinol surface coating- it can’t be washed off.
The only solution I can think of (once the weather warms up) is to coat the timber with an exterior PVA sealant and then paint again with the Cuprinol treatment.
Can anyone suggest an alternative solution?
With many thanks
