In recent years, latex paint technology has changed drastically. They have approved adhesion performance, mold and mildew performance, low VOC emissions, Low temperature application, “meaning, before you couldn’t paint when temperatures were below 50 degrees,” with improved formulations you are now allowed to successfully paint in temperatures as low as 35 degrees.
Latex paints also expand and contract unlike oil paints. House paints must be able to expand and contract with the siding of the house especially in extreme cold and hot climates where the siding freezes and warms back up in the summer. Oil paints are not able to expand and contract and will start to crack and peel much quicker than latex paints for this very reason.
Latex paints are more resistance to fading, chalking, blistering and pealing as the paint has the ability to breath, unlike oil based paints. Oil paints yellows over time.
If the surface of the structure is extremely weathered we may recommend an oil primer instead of a latex primer due to the dark staining or tanning of the weathered wood. Oil primer has the ability to seal severe stains better than a latex primer in certain situations.
Latex paints have far more advantages over oil paints and will outperform oil paints 99% of the time.
