What You Should Know about the Painting Exterior Brick Primer in Glencoe

One of the most common method to prevent corrosion in metals is to cover up the surfaces with painting exterior brick primer in Glencoe. This prevents the flow of current whenever the metal is in contact with water.

To be effective, the first coating on the bare metal must have a very strong bond. This first paint coat is called the primer coat.

This primer paint coat is used to protect the base metal area as well as to provide good adhesion for the topcoat. Surface preparation is of utmost importance. It is useless to have a good primer when the surface itself is covered with loose dust. The primer coat will simply peel off later because the bond is weak.

For heavy-duty paint coatings, the surfaces need to be cleaned by sand-blasting. The idea of sand-blasting is to bombard the surface with abrasives under high pressure to scrape it clean to the bare metal. For less stringent coatings, wire-brushing is good enough.

Choosing the correct paint to suit the environment will ensure good protection for many years.

Epoxy paints provide very good protection from corrosion. This is because of the impervious nature of the epoxy coating layer. These are excellent for protection against corrosive chemicals, salt and fresh water abrasion and are ideal for steel piles, marine structures, ballast tanks and sewage treatment plants.

Polyurethane paints are used in body paint and auto paint of cars. These produce high gloss and are excellent body repair paints with good durability. These are special paints for special applications.

For architectural paint applications in the homes and buildings there are paints specially formulated for exteriors as well as interiors. Obviously those paints manufactured for exteriors will offer more protection from the effects of weather like rain, sunshine, fungus growth, rot, insect attack, and rusts.

Exterior applications includes masonry walls, brick walls, ceilings, wooden doors and windows, roof tiles, metal gates or other structures.

For wood, there are wood primer sealers available as the first coat. Similarly, there are sealers and primers for roof tiles and metal.

Choose the top coat to suit the application. If your area is humid, probably you will need to have some fungus or mildew protection. For outdoor wood application, you may like to use transparent varnish coatings to bring out the beauty of wood. Just make sure that the varnish contains ultraviolet protection in the formulae. Walls that are often exposed to water may need some sort of silicone water repellent.
