I want to paint outside walls.
Be sure to wear overalls/coveralls – a durable or disposable model, before working with exterior paint. Wear light gloves with good fingertip sensitivity and a warmer version when it is cold. A dust mask (with at least a FFP3 filter) is not a luxury. After all, a lot of vapours and chemicals are released when you paint. Are you going to work with a spray gun? Always wear a face mask. Want to work with a paint gun? Wear a pair of well-fitting safety goggles. Always read and follow the instructions on the packages.
