It is important on how you lay your deck
It is key that Installation of your deck is done right. Why ? You get issues down the track but by that time it’s too late to fix and basically will need to have the deck re-built. Take this deck at the front of the house. gaps between the boards are not spaced properly, framing not treated correctly and incorrect fixings.
We took up the old decking, repaired the framing and Installes 140x19 Merbau Decking using stainless steel fixings. On top of that washed it down with Intergrain Power prep and Reviva before oiling it with Intergrain Ultradeck Natural Oil. The difference is day and night.
