How to Remove surfactant Leach

Surfactant leaching cause blotchy, tan, glossy brownish spots that appears on the exterior of a latex paint, surfactants are not necessary in making paints, they evaporate and they do not belong to the ingredients of the paint. They do not cause any harm so you don’t have to worry much. Leaching often occurs during cool weather conditions or the day before the weather cools down.

Wall leach

These are some helpful tips you can do to prevent surfactant leach from appearing:
> Do not paint if the weather conditions are below 50 degrees or during late afternoon.
> If blotching and stings appears you can rinse it with a garden hose.
> Leaching shouldn’t affect the durability of the paint.
> A dish detergent and sponge can also be use.
> Most of the time weathering removes the stain itself for a couple of months.
> Avoid painting during late afternoon.
> Do not paint during spring season and fall.
> Do not paint during rainy days.
> Use oil base paints when you live in a humid area.
Ceiling leach

The spotting happens when humidity condenses on the new paint and draws the surfactant quickly. This can be avoided when you take proper precautions when applying paint. Most of the time this leaching condition cannot be avoided especially when you live in a cool damp place. Sometimes, there’s nothing you can do when you know you have tried everything you need to do to avoid it.
