Bought house with suspected untreated pergola, I am painting it asap to stop rot, house is brand new. Can you tell me if the products bought and process is correct to protect it?
I have sanded, primed with Dulux 1 step prep and 2x coats of cabots exterior deck paint - this has all been done to decking and pergola.
See below photos prior to the above work :
See report from building inspector and photos.
Main Building
Pergola
Timber - exposed to weather
The beams of the pergola that has been built appear to be laminated veneer lumber
(LVL) and it is unclear whether it has been treated for external use. Veneer lumber has a tendency to move and the veneer come apart when exposed to weather.
External timbers that are frequently exposed to harsh weather conditions require adequate protection in order to maintain their condition. Where timbers have not been painted or treated adequately, general deterioration is likely to occur at an accelerated rate.
If left unattended, replacement of these timbers is likely to be necessary in the short-term future. Adequate treatment of these timbers is required as soon as possible by a painting contractor or general handyman.
