Exterior House Painting Tips!
Typically when
painting a house, you are dealing with wood, composite, metal, and plastics. The same basic procedures are required
of nearly all paintable exterior surfaces. The most important step is preparation! Even using the highest quality paint and the best quality applicators, if you do not prepare the exterior surface properly, your paint will fail.
Step 1: Remove all loose paint, rust, and other debris. There are a variety of tools to assist with this, such as: Paint scrapers, putty knives, sandpaper, wire brushes & even chemicals.
Step 2: Clean area thoroughly. Dirt, chaulk and mildew will interfere with the paint's ability to do its job! For general cleaning, TSP does a good job in preparing an area for painting. It is available in liquid and powder form, consider using a pressure washer with a mixture of bleach and water for cleaning mildew . This will kill the mildew and prevent it from coming back later. Allow the exterior of the house to dry. Next is primer!
Step 3: Choosing Primer: This is a very important step in proper outside painting. Lack of primer is often the reason that many home-owners are not satisfied with their exterior paint job. Primer acts as the glue between the surface and the paint. It adds that extra adhesion needed. Most paints are not chemically formulated to bond properly without primer.
Exterior primer is important in Florida!
Step 4: Choosing a paint: Be sure the paint is for exterior use. There are a variety of sheen levels to choose from, flat, satin, semi-gloss, and gloss. Two basic types of exterior paint are Solvent based and Latex based. Latex paint cleans up with soap and water & performs well with exteriors in Florida. Technology has given us "Latex Acrylic Paints" that are best for Florida's climate, allowing the surface to breath and in many cases expand & contract. Oil based paints hold up fair to climate, however Oil doesn't allow the surface to "breath" as well. All exterior paints are washable, ask your local paint outlet for recommendations on the products that will last the longest, and offer the best protection. Estimate the number of gallons you will need (one gallon covers roughly 350 sq. feet), and choose your color! Don't forget to pick up a brush, roller, paint bucket, grid, painting tape. Planning your exterior paint project will save troubles later!
Step 5: Primer: you apply a primer the same way you apply a paint (typically with a brush or roller, and sometimes with a sprayer). Apply to the whole area completely and allow to dry. This will add to adhesion, and lessen the amount of paint you will need to finish your exterior painting project.
Step 6: Painting: Decide which applicator will do your job best and go! Use bumpers on all ladders for stability and drop cloths to ensure neatness. Once you have your project completed allow drying time! Allow a painted exterior surface to dry for 24-48 hours before re-coating (unless specified on the can). Even if paint feels dry to the touch, it may still not be cured, that could cause the top coat to falter.
Step 7: Drying time: Depending on what you are painting, climate, and paint type, drying times will vary. Read the can for specific information about drying time & clean up of tools. Remember Florida's humidity can fool the exterior paint!
