The door is in good condition, was new a few years back and so has only
had one coat of gloss on top of the undercoat. A few small cracks have
appeared. Want to paint it again.

Do I need to undercoat it? If so is it ok to undercoat with a white
undercoat and then paint it with black gloss? Or can I directly apply
another coat of gloss seing as its in good condition

Any recommendations of paint would be appreciated?

Rub it down with wet&dry to get a nice smooth finish and use a GOOD paint
brush with johnson's exterior gloss paint

It depends on the paint. Some paints *claim* to cover in one coat, without
an undercoat - but if it's subject to rain and sunshine, I think I'd use a
conventional paint which *does* require an undercoat.

Either way, you'll need to sand it to provide a key for the new paint. Your
paint tin will tell you what colour undercoat to use - probably grey rather
than white for black paint.

If at all possible, take the door off and lay it on a couple of tressles to
paint it. You'll get a much better finish - with no runs - when it's
horizontal rather than vertical.

Black paint is more likely, than any other colour, to blister/peel if your
door is subjected to prolonged sunshine. Make sure that the wet and dry
rubdown covers every mm of the surface to get a good key for the paint to
stick. Don't expect the paint to smooth out the small cracks. They will
need filling and smoothing.

"Black paint is more likely, than any other colour, to blister/peel if your

What a load of tosh, the reason the painted probably blistered/cracked was
because it was cheap paint used or spors of sap in the wood was still
evident, or even grease from handling the door was not rubbed down with
white spirit before priming.

Black paint will get *hotter* than lighter colours in strong sunlight -
because it absorbs more solar radiation. Whether that makes it more likely
to crack and blister, I don't know - but I would have thought that it was in
with a chance!

What a load of tosh,

It certainly isn't. I had some dark blue paint and some light yellow
paint of the same make on similar substrates facing SW, the blue paint
certainly did fail sooner than the yellow, and Dulux for one recommend
not using dark colours on surfaces exposed to lots of sun.

However....

the reason the painted probably blistered/cracked was
because it was cheap paint used or spors of sap in the wood was still
evident, or even grease from handling the door was not rubbed down with

It's quite possible that this is a reason in this case, but that doesn't
mean repainting with black is necessarily a good idea.

That's not necessarily a bad thing. Dulux recommend 2 coats of their
undercoat and one of top coat of their weathersshield paint IIRC.

A few small cracks have
appeared. Want to paint it again.

Do I need to undercoat it?

Yes. it's as important as the topoat

If so is it ok to undercoat with a white
undercoat and then paint it with black gloss?

If you want, but I'd use a dark undercoat as well.

Or can I directly apply
another coat of gloss seing as its in good condition

don't spil the ship for a happorth of 'tar...

I've always been happy With Weathersheild. The trade one is bit better
probably, they do claim a longer life.

Thanks

I'll get some wet and dry paper, probably undercoat. Have just found a
Leyland paint shop locally - so will see what they have in..

Put a squirt of washing up liquid in a bucket of water and use the wet&dry
and you'll be suprised how easy it is to get a smooth sanded finish.
work in a circular movement, then when all the door is done wipe down with
a damp cloth.
Before priming wipe door down with white spirits and let it dry out
naturally.
I'd use a roller to apply the primer and paint brush for gloss.

That should do ya for at least 3 years. :-)

Consider using a flexible exterior gloss. It will last longer than
ordinary gloss.

What do you mean by "wet and dry" sanding ?

I'm thinking of doing my front door soon, and was just planning to (I
guess) normal dry sand it smooth, and then paint it in a standard
weathershield paint (it's a metal door).
What would wet and dry sanding do, and how do I do it ?

[snip]

Using wet&dry(carborundum)sand paper is basically for paint on metal and
gives a very smooth finish, with use of the finer wet&dry and a bucket of
water and washing up liquid makes the job much easier to sand the paint
rather than the conventional wood sandpapering.

You just keep dipping the wet&dry in the water and apply to the paint
surface in a circular motion, don't rub too hard as you don't want erase
the paint fully.
Basically what your achieving is getting a mirror like finish on the final
coat of paint.
This technique is used by the old coach builders.

I'm not sure, but since I would buy my W&D paper from my local car shop I
would expect them to advise me. Mind you there's probably a website. There
usually is.

Grade 180 is quite adequate for this but must be wetted then applied.

While we are on this subject, what would be the best type of paint
system to use on a new hardwood (don't know which wood) door?
I would just use a microporous stain like the current door, but SHMBO
wants a gloss finish this time. (I think Red was discussed...)
At least I managed to persuade her that we really *didn't* want a uPVC
door
