Removing paint from plaster structures
Tracy McKibben
Is it possible to remove paint from plaster structures? I have a Woodland
Scenics tunnel portal that I painted with Woodland Scenics Stone Gray
paint, and am not satisfied with the coloring I achieved. I would like to
repaint it using a lighter "concrete" color, but I haven't figured out how
to remove the other color. Painting over it won't work, it just blends in
with the original gray color.
TIA

Hmm... I think sanding or scraping is just about the only way to remove paint
from plaster if the paint has been absorbed in the surface and solvents don't
help. If there's no fine detail on the surface, you could try sanding lightly
with fine paper and scraping the toughest places. Is this a stone or concrete
portal? Is the paint solvent or water based? Has it dried completely?

From the above I am guessing that you are using thin washes or stains on the
plaster, if so there is probably no way to remove the colour, you best bet
would be to prime and completely seal the surface and apply new paint over
that surface. A spray can of light grey primer should give you a reasonable
starting point.

to bleech the plaster, I have tried this on stone (plaster )myself but only on very small areas!!
Caution must be used!! Both the for the users safety and for the item.
The other safer method is to paint the face with Jesso (SP?) a water based
product that when dry will take stains or paint.

Woodland Scenics paint is all pure pigment color with no hardener. These
paints are great for blending and mixing colors because the 'coats' never
cure when dry and any additional color applied just mixes with the previous
ones. If the detail of the castings doesn't suffer, you can seal the
Woodland Scenics 'paint' with a coat of flat (white or other light color)
latex paint. Let it dry real good and start over. Because the tunnel
casting is very porous, it is hard to remove the color from it. However,
wiping or soaking the casting in denatured alcohol may lighten the color
and allow you repaint it and achieve you desired results. Also, if you use
paint which is pure pigment, as Woodland Scenics is, you may want to
consider sealing your finished product with Dulcoat (a flat lacquer) or
some water based flat clear coat to protect the color from 'running' if it
ever gets wet from other scenery projects
