Painting - painting several locations (baseboard, cool room, exterior door and garage door)

Hi.

I have three major questions.

The first one is concerning about painting the baseboard. My baseboard mouldings in the house is wear down so I would like to paint a new fresh coat on it.

Is there special paint that I have to buy?
Which one, latex or oil-based, should I buy for long lasting and aesthetic? Also, what kind of finish would you recommend, egg-shell, flat...?
I will have to sand down and patch up some spots with fillers and in this case, do I just use regular primer for those spots and then paint?


The second question is about painting a cool room(kind of wine storage room like) in the house. Inside the cool room, it's unfinished. It's just regular drywall with plaster spots for the joints.

Is there any special paint that I can buy? (since it's cool room, there might be any moisture or temperature issues that the paint have to endure.)
If I don't need any special paint, could I just pick any brand and any regular paint?
Which one is more durable and appropriate for this job, latex or oil-based?


The final one is about painting exterior door and garage door.
There is slight problem with garage door. The backside of the garage door (bare wood) seems (looks like) to be damaged by water.

Is there anything that I could do to prevent from further damage and protect it for the future?

Do I also paint the backside as well?

For the paint job, if I painted them with oil-based 5 years ago and want to paint with latex this time, could I just strip the paint and start with latex? Or is there any other solution? Which one is more durable and appropriate for this job, latex or oil-based? and what kind of finish?

Thank you for any advice and recommendation on any of the problems that I mentioned above. :)

Woodwork can be easily painted with a good semi-gloss latex. Clean it with TSP or spic and span, and rinse. Make any repairs. Smooth out any irregularities with 120 grit sandpaper. Lightly sanding all the woodwork can make the coverage better. Prime any repaired or bare areas with a good primer such as Zinsser 123. Two coats of paint on the baseboards will help the finish endure the beating they get.

For the cool room with sheetrock walls, a PVA sheetrock primer followed by latex wall paint will do fine. The latex will allow a certain amount of moisture to naturally transpire through it. If there will be moisture clinging to the walls, then the moisture should be controlled and eliminated as it will eventually cause any paint to fail.


It is unfortunate that the other side of the garage door was not painted originally. For the lower 1/2 of the door, caulk all seams and joints with a good quality acrylic latex caulk. This includes the bottom edge of the door. It may be necessary to remove the rubber seal to do this, then reattach it. Prime the unfinished side with the rest of the Zinsser, then paint with a top quality exterior latex house paint. Semi-gloss is commonly used on woodwork. The primer will keep the water stains from bleeding through the finish paint.

It is not necessary to remove the oil paint. A cleaning with TSP or spic and span will make it clean enough to paint. A light sanding to knock down the sheen can help the primer adhere.

Hope this helps.

Thank you for the advices.
I think everthing is set and time to get paint.

Thank you again.
