Porta recommends factory applied pre-coating to protect the timber during transport and installation.
Porta Cumaru is supplied with end grain sealer on exposed end-grains before delivery. Porta recommends applying an end grain sealer to cuts on site.
End Sealing Guidance
A maintenance schedule is recommended to preserve the dimensional stability of timber and protect the timber from UV and moisture. Apply coatings as per the manufacturers’ recommendations. To retain colour regularly apply a tinted pigmented coating, for a silver-grey appearance, select a clear unpigmented coating.
Porta Cumaru is a very dense, extremely hard-wearing Class 1 sustainable timber.
