Semi-Transparent Stain:
Stain that changes the natural color of the wood, but allows the grain and texture to show through.
Set Up:
Drying (e.g. latexes, alkyds) or reacting (e.g. two component epoxies, urethanes) to the stage where the material no longer flows or is workable.
Sheen:
The low angle gloss of a surface measured at 85 degrees.
Shop Painting:
Surface preparation and the application of coats of paint in a shop or plant before shipment to the site of production.
Shop Primed:
A temporary (or permanent) prime coat applied at a factory, shop, or other off-site location.
Solids by Volume:
The total volume percentage of non-volatile material. Also known as volume solids. The solids by volume is used to calculate the dry film thickness (DFT) of a coating from wet film measurements taken during application.
Solids by Weight:
The percentage of the total weight of a coating occupied by nonvolatile compounds.
Solvent:
The volatile part of paint composition that evaporates during drying. Solvents are used to control the consistency, drying properties, and in part, the stability of the liquid paint material and to regulate its application properties. Various types of solvents are also used as cleaning agents, often in combination with surfactants.
Spalling:
The chipping or fragmenting of surface or surface coating. Spalling, in concrete substrates, is generally attributed to the absorption of water with subsequent freezing, although also occurs due to the rusting and subsequent expansion of reinforcing bar (rebar) close to the surface.
Spray (ing):
A method of application in which the coating material is broken-up into fine mist and directed onto the surface to be coated. Atomization is generally created by compressed air, but other methods are direct pressure (airless spray, piston pump) and centrifugal force.
Spreading Rate:
The area covered by a unit of volume of coating material, frequently expressed as square feet per gallon. Spreading rate will vary with the operator, the method of application, and the nature of the surface being coated.
Stain:
A solution or suspension of coloring matter in a vehicle designed primarily to be applied to create color effects rather than to form a protective coating. A transparent or semi-opaque coating that colors without completely obscuring the grain of the surface.
Streaks:
A surface defect characterized by essentially parallel line of different colors or shades
Stringers:
The side boards used to support the steps on a staircase.
Substrate (Substrat):
In painting, any surface to be painted, including wood, concrete, masonry, steel, other metals, and various other materials or previous paints. A substrate can therefore be bare or covered. A previously unpainted surface sometimes is called the “original substrate”
Surface Conditioner:
Preparatory coating applied to chalked, painted masonry surfaces for bonding chalk and improving the adhesion of subsequently applied coatings.
Surface Drying:
The drying of a coating on the top surface, but not uniformly through the film. Often this can lead to wrinkling or cracking when the firm fully dries.
Surface Tension:
The surface phenomenon exhibited in varying degree by all materials. Where the surface tension of a material is lower than a liquid, the liquid will not spread out over that surface. Where the surface tension of a liquid is lower than that of the surface, then the liquid will spread out.
Surfactant:
An acronym for Surface Active Agent. Used to break down the surface tension of liquids to make them more miscible, such as in oil and water emulsions. Surfactants are divided into small classes that are relative to their functionality such as dispersants, emulsifiers, detergents, defoamers, etc.
Surfactant Staining:
The appearance of yellow to brown colored spots (horizontal) or streaks (vertical) on the surface of a recently applied latex coating. Commonly seen on latex semi-gloss paints applied to the ceiling of a bathroom where water condenses, and on some highly tinted exterior latex coatings when exposed to moisture.
Tack Rag:
A piece of loosely woven cloth dipped into a varnish oil and wrung out. When it becomes tacky or sticky, it is used to wipe a surface to remove small particles of dust.
Tackcoat:
A thin mist-like initial coat still soft enough to accept remainder of the coat as part of the same coat application and done in order to avoid sags and runs.
Tannin:
A water soluble, natural stain in woods, such as cedar and redwood, which is usually composed of various phenol compounds.
Tannin Bleed:
A water or solvent soluble extractive in a wood substrate that will migrate through a porous paint film and deposit a yellow to reddish brown stain on the surface.
Tannin Blocking:
The process of making tannin stains insoluble by means of a chemically active or moisture impermeable primer so they cannot bleed through to the topcoat.
Tape Test:
An adhesion test using a series of intersecting cuts or an X cut through the surface of a coating or coating system that extends to the substrate. A special pressure sensitive, one inch wide tape with an adhesive bonding strength is applied to the cut surface, then pulled back smoothly at an angle of 180 degrees. The cut area of the film is then examined and rated relative to the coating remaining.
Telegraphing:
Physical marks or textures on a substrate that show through an applied film.
Test Patch:
A small representative area to which a coating is applied in order to test its compatibility, appearance or adhesion properties. When choosing a coating for a substrate or situation in which there is some element of uncertainty, a test patch can provide helpful information required to ensure a correct decision.
Theoretical Coverage:
The coverage of paint calculated from volume solids and recommended dry film thickness. The theoretical calculation does not consider losses due to overspray, spillage or other losses.
Thinner:
A compatible, volatile liquid used to modify the solids content, drying speed, consistency or other properties of a paint, varnish or lacquer. Also used for cleanup of oil or alkyd paints and application tools. See Solvents.
Tint:
A color produced by mixing white pigment or paint in predominating amount with a non-white colored pigment or paint. The tint of the color, therefore, is much lighter and much less saturated than the color itself.
Tipping Off:
Brushing technique involving the use of the tips of the bristles to smooth the applied finish.
Toner:
Pigmented lacquer sealer that is applied by spray. Toners provide color and make the surface appear more even.
Tongue & Groove (Tongue-in-Groove):
A joint formed by lumber machined to have a groove on one side and a protruding tongue on the other side so that pieces fit snugly together, with the tongue of one fitting into the corresponding groove of the other.
Touch-Up:
The ability of a coating film to be spot repaired (usually within a few months of initial painting) without showing color or gloss differences.
Transparent:
Having the property of allowing light to permeate without diffusion or scattering; clear.
Trim:
Finishing components used in construction, such as moldings, char rails, base boards, etc.
Trisodium Phosphate (TSP):
A strong alkaline chemical used for cleaning, degreasing and dulling surfaces prior to painting.
TSP:
See Trisodium Phosphate.
Urethane:
See Polyurethane.
