Idigbo and "special" primer

[Steve Maskery]

Hi all, I've finally got round to making my windows. I should have heeded the advice of whoever it was that suggested idigbo was dodgy stuff. I don't like it at all, quite woolly and not very stiff. On the upside it is very light, I man-handled a 4.85m length of 9x3 onto the SCMS myself. OK it was a struggle, but in oak it wold have been impossible. Even pine, too, probably.

Anyway, to the point.

My brother-in-law has been building his extension for years, and has finally got round to the doors. They are idigbo, too, and have arrived primered (primed?) wit "special" primer. Unfortunately he didn't know what was so special about the primer, so neither of us is any the wiser. Does anyone know what this could be?

Cheers
Steve

Moisture vapour permeable stuff is all that springs to mind.

Its pretty difficult stuff to paint IME - so it may be just extra grippy primer. Crown do a good one.

Hi Steve,

The old favourite for wonky timbers that were tricky to finish was aluminium primer.Great for resinuous tibers as it's self knotting, but also a great general purpose one.
You'd spot it though as the timber becomes more silver than a Cyberman!
Saying tha, I haven't seen it for age. Probably too dangerous nowadays... :roll:

I tried the Aluminium primer on Idigbo on our conservatory cill - even that lifted (after cleaning with meths etc etc) so in the end we used Superdec stain which I have to say is fab.

So what is it about Idigbo which makes it so reluctant to take a finish?

 

[Jake]

Ah, to answer my own question, high tannin levels seem to be a factor, like with Oak.

The details on this product at AGWoodcare mention suitability for Idigbo, etc http://www.agwoodcare.co.uk/gbu0-prodsh ... secur.html (click on the technical link) but it mostly burbling on about bleeding through, rather than lack of adherence.

Great, thanks chaps, much appreciated!

Steve,

We use the full dulux weathershield system, and the first coat is a preservative.

Idigbo is full of yellow staining stuff which will bleed from exposed surfaces.

The weathershield is good stuff, in this near the north coast of devon climate we are getting at least six years, before repainting, (white of course).

I'm sure the Idigbo will last a long time........

best wishes,
David
