External merbau sill and jamb sealing

Hi all,

I just received my entrance door from the joinery department. They recommend I seal the merbau straight away with Sikkens or similar before it starts to leach. They over emphasise the sealing under the door sill before installation.

I wander down to the paint shop today to get the Sikkens and the guy really tried to persuade me from sealing the merbau for 6 months to give it time to bleed.

The door and frame will be exposed to the elements so I need to do something. My options are:

1. Don't seal it before installation and have my warranty void, have the merbau bleed all over my colourbond cladding below, and worry that I'll never get a chance to seal under my sill once installed.

2. Seal the joinery before installation to keep my warranty intact and face the unknown concequences of a sealed (timebomb????) merbau just waiting to bleed out.


I would have thought that by sealing the timber before it gets wet would lock up any chance of it bleeding out. If it was a deck I wouldn't be concerned but it not and this door cost me a lot of money and pain and suffering so I want it right.


Please guys any suggestions or experience here? I really need to get this door installed soon.


Also, the joinery people do not recommend water based acrylic sealers. The people at all three paint places I went to all recommended water based as it doesn't yellow but they were also the ones who insisted on not sealing the timber at all before installation.

cheers,
