What is a good decoupage sealant for painted coffee tables?

Question

I want to use a strong sealant for my coffee tables. I painted, then decoupaged color copies onto them. When I used a lacquer sealant, some of the colors from the copies ran. Any ideas?

Answer 1

I would use a waterbased poly in a spray can...lightly mist it so it doesn't disturb the color copies. Build it up slowly.

Answer 2

To prepare your tables for paint you need to know how they are finished. If they are painted or lacquered wood it will be easy to finish. Some furniture is covered in plastic laminates. This can be painted as well but you will need to use a special paint that is made for plastic. No matter what the finish is make sure the surfaces are clean and dry. Any oil, grease or wax will prevent the new finish from adhering. For painted or varnished or lacquered wood.... You just need to use sand paper to degloss the finish. It can be medium to fine sand paper. You don't want the sanding scratches to show through the new paint but you want to create a bondable surface. If the old paint is very glossy it would be a good idea to use a primer, as well. Primer is also helpful when you are making a big change in color like from a really light color to a really dark color or vise versa. For plastic laminates.... Be sure the plastic is clean and dry. Use a platic primer to evenly coat the surfaces. Spray primer is best for this. After it is well primed you can coat with any paint that you want. Whether you use spray paint or a brush is up to you. You can achieve very nice results with either. It is also possible to do a sloppy job with either. When spraying it is better to spray several light coats than one heavy coat. It will proably just run. When brushing it is worth it to buy a good quality brush. You will want a brush with fine bristles. Careful painting can result in the elimination of most of the brushmarks.
