The Secret to Spray Painting Without Sanding
This furniture tip is for people looking for a way to eliminate the extra preparatory work in painting their furniture; who think they can save time and cost by not sanding their wood furniture.
The usual procedure in preparing wood furniture for painting includes sanding the surface in order for the paint to adhere properly. However, some people do not have time for sanding or they just simply hate the part of the job. There is a way of skipping it though. But it does not mean that you should neglect sanding your piece every time you do some painting job.
Sanding the wood furniture before coating with paint is what makes the difference between work that looks great and something that has been done hastily. I had already mentioned this necessity in my earlier post Spray Painting Tips for Your Wood Furniture
Bonding primer eliminates the need for added surface preparation such as sanding. Intended for use on glossy surfaces, bonding primer can be used not only on metal or plastic but on wood furniture as well. Other than applying by spray painting, bonding primer can also be brushed-on on any glossy surface.
If you are refinishing or putting on a new coat over the old finish you must first clean the surface of contaminants such as wax, polish, grease or oil. You can use an abrasive detergent or just plain soap and water. After all is cleaned and dried you can then go ahead to applying the primer
The purpose of bonding primer is to seal the surface of pores in wood as well as to block wood tannin bleed, ink, grease and other stains. But their most important job is to ready the surface for the painting by creating a uniform surface.
Several paint manufacturers sell different types of bonding primers according to the project requirements. STIX Bonding Primer is a waterborne urethane acrylic that strongly bonds to hard, glossy paints and other challenging substrates aside from wood. It levels to a smooth film to dramatically improve the top coat appearance.
