Acrylic exterior paint

Exterior Paints Buying guideA coat of exterior or outdoor paint not only creates an attractive appearance for years to come, it also protects surfaces from moisture, fading and temperature changes. A high-quality paint will provide better protection, complete coverage, easier application and longer-lasting results. When it comes to buying paint, you have lots of choices, some determined by your application and others that are based solely on your preference. Before you learn about all of the options available to you, use the following questions to focus in on the needs of your project:
• What types of exterior surfaces do you plan to paint?
• Are they chalky or layered with previous coats of oil paint?
• Are you painting bare wood, metal or concrete?
• Does the surface require frequent cleaning or have imperfections?

Quality, Types, Tips and Primer

High-quality paint is important for any project, but it’s especially important for exterior projects, which are subjected to harsh weather conditions day in and day out. Take some time to consider long-term benefits of better exterior paints in addition to their initial cost. A good paint will require fewer coats and last longer, saving you money and time in the long run.

Water-Based vs. Oil-Based: In general, water-based paints are preferred for most exterior applications, but oil-based paints may perform better under certain conditions. Water-based paints are flexible enough to expand and contract with the siding on a house, they’re breathable, so they won’t trap moisture and crack or peel, and they dry significantly faster. Oil paints usually take between 8 and 24 hours to dry, while water-based paints dry in just 1 to 6 hours. Oil-based paints offer better adhesion and stain blocking, so they’re better for chalky surfaces, stained surfaces, bleeding woods (tannin or sap) and metals that rust.
• Water-based paint can be applied over oil-based paint, but oil-based paint shouldn’t be applied
over water-based without the use of a primer first.
• Latex paints with an all-acrylic binder hold up to weather better than latex paints with a vinyl-acrylic binder

Paint Base

Description

Major Advantages

Oil-based (alkyd) Consist of a pigment and resin in a solvent thinner. When thinners evaporate, the resins form a hard coating, leaving behind the pigment (which provides the color).

• Better surface penetration

• Better adhesion

• Wearability

• Better flow and leveling

• Dries to a smoother finish with
fewer brush/roller marks

Water-based (acrylic; latex) Consist of a pigment and binder with water used as carrier.

• Better gloss and color retention

• Breathable (won’t trap moisture)

• Quicker drying

• Less odor

• Nonflammable

• Soap and water cleanup

• Low VOCs (Volatile Organic
Chemicals)


Primer: Bare wood and some other bare surfaces need to be primed before you paint them. Like paints, primers come in oil- and water-based varieties. Oil-based primers are suitable for use with oil- or water-based paints, so you could prime a chalky surface with oil-based primer for better adhesion and still take advantage of the benefits of latex paint. Water-based primer is not recommended for use under oil-based paint.
• Water-based primers are recommended for most applications, but oil-based primers are preferable for
stained wood, bleeding wood (sap or tannin) and metals that rust
• There are specific primers for wood, concrete and certain metals, such as galvanized steel, iron and
aluminum
Paint Types: Unlike interior paint, exterior paint must withstand a variety of harsh external influences. For this reason, exterior paint is offered in several "specialty" formulas designed to meet the specific requirements of your substrate. Use this chart to select the paint that is appropriate for your outdoor painting project:
