What is Sealer? | Definition of Sealer? ›

A sealer is a type of coating that is used to seal a surface before the application of the topcoat. Sealers are typically used on porous surfaces, such as concrete or brick, to prevent the topcoat from being absorbed into the surface.

Definitions of sealer. 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) synonyms: sealant. types: caulk, caulking. a waterproof filler and sealant that is used in building and repair to make watertight.

Sealers are thinned varnish, shellac or lacquer and are used to prevent absorption of surface coatings and also to prevent the bleeding of some stains and fillers into surface coatings, especially lacquer coatings.

seal verb [T] (CLOSE)

to close a container or opening, or to prevent the escape of a liquid or gas from something: Rubber seals jars tightly. He sealed the envelope and put a stamp on it.

Sealers may penetrate into the surface or form a very thin surface layer (typically less than 3 mils). Thicker surface treatments usually are called coatings. Sealants, sometimes called caulks, are used for filling voids, gaps, cracks, and joints.

: a tight and perfect closure (as against the passage of gas or water) (2) : a device to prevent the passage or return of gas or air into a pipe or container. 3. : a seal that is a symbol or mark of office.

The definition of sealing is the process of fastening or closing something securely. In clamping, there are two main theories on sealing. Flexibility makes the seal. For softer hoses the complete clamp needs to be as flexible as possibly can. Enhanced flexibility of the clamp will result in faster and better sealing.

While floor sealers protect floors by penetrating into the pores of the flooring material, the importance of a floor's finish is, of course, the protective surface layer that is the first line of defense against floor damage.

Seals and sealings were two different forms of imprints. Both of them refer to the same object. Sealings were the instruments used to make seals that were essentially imprints. Seals were the instruments used to make sealings that were essentially imprints.

What is a seal example? ›

Something that seals, closes, or fastens tightly or securely; specif., a piece of metal, paper, etc. so placed over a lid, cap, etc. that it must be broken before the container can be opened. Webster's New World. A stamp, signet ring, etc., or the signet itself, used in making such a design.

The word “SEAL” at the end of (or below) a signature line means 'signature'. For example, a mortgage note or Fannie Mae/Freddie Mac Texas Deed of Trust will have “(Seal)” at the end of the line for the borrower's signature. A person's signature is considered their seal.

Silicone Sealants

Silicone is very flexible and acts as a water and moisture repellant, making it among the best caulks for both windows and bathrooms. Pure silicone is more expensive than latex caulk, but it is highly durable.

Generally speaking, in most cases, a new solvent-based concrete sealer can be applied to a surface previously sealed with a solvent-based concrete sealer; however, it cannot be applied over a surface previously sealed with a water-based concrete sealer.

The best materials for sealing are engineering plastics. They are strong, durable, and they don't corrode when they come in contact with water. There are many materials that can be used for sealing. The best material for sealing is one that is not only strong but also flexible and lightweight.

Sealers are semi-permanent floor coatings that look and wear more like paints than like floor finishes. When compared to finishes, they are usually harder to apply correctly and much harder to remove. Also, the chemical makeup of most sealers is more complex than that of finishes.

The key distinction between caulk and sealant? Elasticity. Caulk is typically made from a mixture of latex and acrylic materials, which make it more rigid and prone to shrinking when cured. A sealant offers superior elasticity and water resistance because it primarily contains silicone.

What's the Different Between a Sealer and a Waterproofer? Sealers and waterproofers perform similar functions, but they differ slightly in how they work. A wood or concrete sealer will protect the surface. Waterproofers are more durable than sealants because they penetrate the surface, filling in leaks or gaps.
