There are two types of oil stains, penetrating and non-penetrating. Penetrating oil stains contain dyes and resins that penetrate the surface; non-penetrating oil stains contain larger amounts of pigments and are usually opaque or transparent.

opacity
The ability of a paint to hide the previous surface or color.

A compound that softens old paint or varnish and permits scraping off the loosened material.

patching plaster
A special plaster made for repairing plaster walls.

peeling
Detachment of a dried paint film in relatively large pieces, usually caused by moisture or grease under the painted surface.

pigments
Paint ingredients mainly used to impart color and hiding power.

pihnole
Very small holes in paint film, usually not deep enough to show undercoat.

plaster of paris
A quick setting, pure white powder, used to set bathroom wall fixtures such as towel racks or used by craft groups for pouring molds and making plaster objects.

polyurethane
Wide range of coatings, ranging from hard gloss enamels to soft flexible coatings. Good to very good adhesion, hardness, flexibility and resistance. Surface preparation critical.

polyvinyl acetate
A synthetic resin largely used as a vehicle for many latex paints. Often referred to as PVA.

pot life
Amount of time after mixing a two-part paint system during which it can be applied.

prime coat or primer
The first coat or undercoat that helps bind the topcoat to the substrate.

propellant
The gas used to expel materials from aerosol containers.

putty
Doughlike mixture of pigment and oil used to set glass in window frames and to fill nail holes and cracks.

removers
Substances used to soften old varnish or paint so they may be removed easily.

resin
A natural or synthetic material that is the main ingredient of paint and that binds ingredients together. It also aids adhesion to the surface.

roller
A paint application tool having a revolving cylinder covered with lambs-wool, fabric, foamed plastic or other material.

ropiness
Paint dries with a stringy look because it did not flow evenly onto the surface.

runs
Blemished film caused by excessive flow of coating.

rust preventative paint or primer
The first coat of paint applied directly to iron or steel structures to slow down or prevent rust.

sags
Excessive flow, causing runs or sagging in paint film during application. Usually caused by applying too heavy a coat of paint or thinning too much.

sal soda
Crystallized sodium carbonate. It is used for making cleaning solutions to remove grease and grime from old painted surfaces.

sand finish
Rough finish plaster wall.

sanding surfaces
A heavily pigmented finishing material used for building the surface to a smooth condition. It is sanded after drying.

satin finish
See Semi-Gloss

scrubbability
The ability of a paint film to withstand scrubbing and cleaning with water, soap and other household cleaning agents.

sealer
A thin liquid applied to seal a surface, to prevent previous paint from bleeding through from the surface or to prevent undue absorption of the topcoat into the substrate.

seeds
Small, undesirable particles or granules other than dust found in paint, varnish or lacquer.

self-cleaning
Controlled chalking of a paint film so dirt does not adhere to the surface.

semi-gloss
Having a luster between full and flat.

semi-transparent

The property of a material that causes it to change from a thick, pasty consistency to a fluid consistency upon agitation, brushing or rolling.
