Front door painting

[beatts]

Hi,

I'm going to paint my wooden front door. I'm thinking Miranol potentially, in a dark grey colour, but I'm a bit concerned the surface must be absolutely perfect with this kind of finish.

I've sanded it down today, but what do I need to do about these area around the profiling? Do I scrap out and then fill with wood filler or caulk?

Appreciate your help.

Thanks

Fill.
Could use the repair care 2 in 1 dry flex resin.
It's always worth contacting Tikkurila UK technical

It's a tough one to answer.

Those panels are dynamic. They move as the timber expands and contracts.

Caulk may work, but it might not allow enough movement. It will also shrink back and show the ripples in the finish.

I normally use a sharp chisel to break away the old paint seal (if need be) and then back fill the damaged area with two pack filler. I do however then use something like an oscillating saw to cut through the filler on the molding and flat to prevent both trying to move simultaneously. The 2mm gap, I them fill with a MS polymer "caulk" type product such as CT1. They are more flexible than caulk. Only marginally less flexible than silicone, however silicone repels paint. MS doesn't shrink back and can be primed with waterbased paint.

Regardless of the above, there are no guarantees. I once spent 20+ hours working on a door for a customer. They were happy with the end result but 2 years down the line there were a couple of hairline cracks. In my defence I did tell them that might happen and they didn't give me grief.
