Comparing Oil and Latex Paints
Durability-Good adhesion is probably the single most important property of paints, because it helps prevent blistering , flaking and cracking.
Latex- Top quality latex paints that contain top quality acrylic binders provide maximum adhesion to most surfaces. Latex paints are also very flexible, so they continue to adhere even when temperature changes cause the surface to expand and contract. This elasticity helps forestall chipping, peeling, flaking and other common paint failures.
? Oil-Alkyd paints also have excellent adhesion, and perform better than latex over heavily chalked surfaces. But with time, the alkyd can embrittle, sometimes resulting in cracking in just a few years.
Latex-Top quality acrylic latex paints provide superior resistance to bleaching and fading,, even when exposed to damaging ultraviolet sun rays.
Oil-Alkyd paints fade faster than latex paints. They are more likely to chalk (develop a powdery substance on their surface), which causes the color to whiten.
Ease of Application
Latex-Latex paints glide smoothly from the brush or roller onto the surface. Top quality latex paints are especially easy to apply, since recently developed additives provide even application and spatter resistance.
Oil-Compared to latex paints, alkyd paints are more difficult to apply,, especially when brushing a large area, because they have more “drag”. On the other hand, they go on heavier and give more complete one-coat hiding and coverage.
Latex-Top quality acrylic latex paints contain mildewcides to discourage mildew and help the paint maintain a fresh appearance.
Oil-Alkyd paints, while also containing mildewcides, are derived from vegetable oils which provide nutrients for mildew growth.
Variety of Uses
Latex-Latex paints can be used on wood, concrete, metal, vinyl siding, aluminum siding, brick and stucco.
Oil-Alkyd paints should not be directly applied to galvanized metal. They also require special chemical pre-treatments before use on new concrete, stucco and other masonry surfaces.
Latex-Latex paints have little odor and are non-flammable.
Oil-Alkyd paints have noticeably more odor owing to the solvents and oils they contain.
Latex-Latex paints clean up easily with soap and water.
Oil-Alkyd paints require solvents for clean up, making the chore messy and complicated.
Latex-Latex paints dry in just a couple of hours, so you can recoat quickly. However they are vulnerable in case of sudden rain.
Oil-Drying time for alkyd paints can take up to two days- plenty of time for dirt, insects and people to come in contact with the surface and potential to mar it permanently.
