6. Ignoring the Weather
Make careful to check the humidity levels before you begin any outdoor painting projects. Water-based paints may take longer to dry in environments with high humidity. Consider delaying a day or two if it's going to be really humid.
7. Using the Wrong Paint
You're prepared to repaint an existing surface. You must be aware of the materials you are using. Has the surface had an oil-based treatment? It will peel and break if you try to paint over it with latex paint. If so, you must sand down the oil-based paint before using it to apply your fresh paint.
8. Skipping Primer
Be sure to read the primer. A good surface is provided by primer, allowing paint to adhere well and producing a lovely finish. It will also aid in highlighting the real color you have chosen. Since paint and primer are now available in a single container, there is really no need to omit this step.
In the same vein, choosing the appropriate paint requires an understanding of your finishes.
