Is sanding really necessary between paint coats (house painting)?
Question:Is it really necessary to sand between coats of paint if I'm using a low-luster or satin latex paint? While we're on the subject, how about semi-gloss paint?
Answers:
I'm also assuming this must be for outdoor painting. It really depends on what the surface is. My modular home has T-11 siding on it. I rented a pressure washer and sprayed it off from about 8 inches to remove chips and dirt and grime. I then primed and put a finish coat on.
You'll probably be better off using latex paint because latex is easier to clean and lasts at least as long as oil-based paints. Whether you choose latex or oil-based paint, always purchase the best paint you can afford. Otherwise you're likely to spend lots of time applying additional coats.
Also semi-gloss works well on the trim of a house, it really sets it off from the rest.
no, who told you that? you may have to scrape/sand old paint before new primer. You do not need to sand primer before top coat. I would recommend a semigloss on exterior surfaces.
I am thinking this is for the outside and the more time you take now and do it right the less you will have to do later. If you don't want to go to all that trouble than hire someone but if you do not sand it will peel later with the weather and you will be back out there sanding and painting again. As far as the semigloss I have never heard of that on the outside but hey if you are on the inside walls hey look it is only paint if you don't like it repaint. Also I have never sanded the inside unless there was texture on the walls and I have painted a many walls in my life time. Enjoy
It's not necessary to really sand the surface with alot of force, but what we call as 'buffing' or knocking it down, would be in your best interest. It smooths the surface, taking out lumps or roughness, and helps make the paint bond better. Sanding also helps make the walls finish with a better consistency. Remember,too, latex low-luster, and anything other than flat has to cure for about 30 days, so don't pick at it thinking it's not bonding. E-mail me anytime.
Not really. You shouldn't do it at all. Only sand when the paint is not even or it didn't dry correctly. Otherwise put another coat when the 1st one dries.
Heaven's no, who told you to do that? But, use a roller and roll in a W formation, it covers better with no lap marks. No, to all paint.
