Continuous film that prevents the passage of liquids or gaseous media.

Any finishing material that seals the wood.

Coating which is used on a surface to close off pores so that penetration of liquid is prevented. There are different types of sealer for wood, masonry, asphalt, concrete, etc.

A coating whose main function is to “seal” in, for example, alkali.

a liquid coating that is applied to an permeable surface such as wood or masonry to seal out moisture.

A substance applied to glass and frame surfaces that guarantees consistent adhesion.

A silicone, lacquer, or acrylic based, clear liquid that is applied to cement-based grout to protect against water penetration and stains.

Protective coating applied to surface before and after painting which prevents chemical reactions between the paints and the surfaces they are applied on.

A coating designed to penetrate and provide the initial protection to a floor surface by filling the tiny holes. Also, a product which prevents color bleeding.

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.

a kind of sealing material that is used to form a hard coating on a porous surface (as a coat of paint or varnish used to size a surface)

a special type of primer that is normally used before an entire paint job

a substance used to protect a surface from oxidation, natural deterioration and physical abuse

a tar-like material that you apply to the footing and foundation

Any coating used for the purpose of reducing the absorption of succeeding coats. (See hold-out)

A coating designed to prevent excessive absorption of succeeding coats into porous surfaces or to prevent bleeding. .

A liquid solution which coats and protects your pavers and pavements. Sealers help with waterproofing, color enhancing and stain removal.

Applied before the finishing coat of polish to speed up the polishing process.

A substance usually available in spray form that prevents fading, removal of glitter, chalks etc from your finished work making the image permanent.

solvent or liquid base material used to protect and enhance the appearance of stamped concrete.

An undercoat that enhances adhesion. Provides uniform color holdout and an even, level surface for topcoat application.

A finishing material, either clear or pigmented, that is usually applied directly over raw wood or concrete for the purpose of sealing the wood or concrete surface.

Thin liquid to "close" a surface, prevents previous paint from bleeding through from surface.

Below or on surface treatment for tiles, stone and grout. The job of a sealer is to provide REACTION TIME and to help prevent staining by putting a barrier between the stone and the contaminant.

Clear coatings sometimes applied to unglazed tile floors or grout joints, to protect the surface from grease spills or add lustre to a surface.

Essentially a weak solution of polish applied before sanding which blocks the pores in wood, to prevent cross contamination from dust, and also acts as a primer before the polish proper is applied.

A pigment paint containing stain blockers to prevent the bleeding of oxidized surfaces.

A clear medium applied to a wood surface prior to painting to protect against seepage of sap which could damage the painted piece over time.

a coating designed to prevent excessive absorption of finish coats into porous surfaces; a coating designed to prevent bleeding.

(1) A continuous film or penetrant to prevent the passage of liquids or gaseous media; a high-bodied adhesive generally of low cohesive strength to fill voids of various sizes to prevent passage of liquid or gaseous media. (2) A coating used to seal the sand-scratched surface of a primer in order to obtain a smooth uniform paint base over rough metal. Sealers are products of low pigmentation.

A coating used on absorbent surfaces prior to painting. Semi-Gloss - See "Satin."

Coating designed to prevent bleedout or bleed-through.

A liquid coat that seals wood, plaster, etc., and prevents the surface from absorbing paint or varnish. Sealers may be transparent, and can act as primers. Some sealers are designed to be left uncoated.

A material usually applied as a liquid that is used to waterproof, enhance color, and in some cases reduce abrasion of interlocking concrete pavements.

An undercoat which improves the adhesion of the topcoat, and which seals old painted surfaces that have been sanded.

Any finishing material that is applied with the primary purpose of stopping the absorption of succeeding coats.

Clear solution which protects mosaic from stains & water infusion.

A substance you can add to the liquid in the cooling system to seal leaks. Also called stop-leak. Other kinds of sealing compounds are used to coat surfaces before installing hoses or gaskets. These are effective in preventing leakage but usually make the hose or gasket hard to remove.

Paint product used to prevent bleed through of the previous coat or the sinking in of the new paint, resulting in loss of gloss.

Material applied before topcoat to increase color holdout and uniformity of color and adhesion.

finish in spray or brushed on to seal raw wood before paint is applied.

A surface coating generally applied to fill cracks, pores, or voids in the surface.

Solvent- or liquid-based material used to protect and enhance the appearance of decorative concrete. (Also see film-forming sealer and penetrating sealer.)

A coating sprayed prior to the top coats that can help with color coverage but normally will be used for helping to hide sand scratches and also help prevent the top coats from shrinking into a more porous substrate like primer.

A protective, usually clear, coating applied to wood or metal. Home Improvement Encyclopedia

A clear or pigmented liquid that is applied directly over an uncoated material such as wood or concrete for the purpose of sealing the material against water penetration.
