Concrete Sealants - All You Need To Know

Colored or imprinted concrete decks and driveways require a sealing coat to protect them effectively. However, these coatings only last for some specific time and then fade off. Various factors including wear and tear, salts and chemicals determine how strong the coating is and how long can it last.

There are two prime types of sealers namely solvent or water based that form a layer on the surface and the penetrants that penetrate the concrete surface and provide outer protection as well.

Concrete Sealant:

The word concrete means a hard porous substance that absorbs liquid into its apertures leaving it with quick stains. A concrete sealant constitutes of different silicates, siloxanes, silanes, epoxies, polyester, polyurethanes, acrylics and waxes.

These further simplify into two fundamental categories of film formers chemically reactive sealers or penetrants. To be specific, silicates are the best sealers to protect the damage from salt and water resistant sealers are the best for stain protection.

Concrete sealant forms a protective layer over the concrete's surface. They are water resistant as well. Epoxies and polyesters produce a hard, scratch resistant and much-durable finish.

Sealing Decks:

The process of protecting the floor from fading and losing the grain patterns is sealing deck. Oil sealers contain different types of oils. They are ether penetrants or coatings, whereas some are a combination of both.

Pure coatings form a layer over the wood and protect it from external stains. A product containing linseed oil is a film-forming deck-sealing product. Some constitute of paraffin oil and hence, are the best penetrants. The most famous deck sealers today are water-based wood deck sealers.

These products for sealing decks contain volatile organic compounds or volatiles, which are turpentine or simple mineral spirits.

Wood Sealer:

The use of a wood sealer is for soft woods. It helps to reclaim wild granular mold. wood sealer Permeates the wood and makes it less absorbent for a better grain pattern and color appearance.

There are different types of wood sealers that people use today such as varnishes, water based dyes, colored oil finishers, wood preservatives, water repellants, wood toners and shellac (resin secreted by lac bug). They match well with the variety of coatings and can be a coating over old shellac, varnish or gloss finishes that stick well.

Wood preservatives are classified based on their contents comprising of EPA-registered fungicide.

Concrete Crack Sealant:

Epoxies constitute of cyclic ethers called oxacyclopropanes that stiffen during the polymerization process. It is a product of biphenol A and epichorohydrin reaction. They are famous for high tensile strengths and hence, are expensive. The bond strength of this sealant is higher than other concrete crack sealants available.
