Can You Put Stain Over Paint?
Solid stains work better than transparent stains for covering pre-existing paint coats and can be applied directly onto the wood. Water-based stains are recommended for their ease of use and environmental friendliness, although oil-based stains are more durable and last longer.
If working outside, it is important to stain on dry days that are cooler than 90 degrees Fahrenheit, otherwise the stain job may blister. Before applying the stain, one should remove any peeling paint and cover areas that are not reserved for the new treatment. Once the stain is stirred so that the color is evenly distributed, it can be poured into a paint pan where it is ready for use.
