Hi all, something that has been concerning me for a while is the talk paints only lasting a short time and needs to be re-done 3-5 years for example, fading, peeling off etc. Almost always we are talking about house paints, water based acrylic which is probably the weakest paint on the market. But the most widely sold in retails shops such as bunnings and local house paint stores. For around the same cost or slighty more you can can use 2 pack industrial paint. Usually consists of an epoxy undercoat, followed by a gloss polyurethane topcoat to make it pretty. Epoxy's will slightly chalk when exposed to UV, hence the need for the polyurethane topcoat and the gloss factor. Which lasts forever. I recommend this for steel, alumnium, concrete driveways, external wood. The downside is when an unsuspecting person goes to paint over these with weak waterbased acrylics from bunnings it will just drip off. You also dont need to re-prime over polyurethane, you just topcoat again after normal preperation and your good again for another heap of years. I would not recommend using these types of paints for internal uses such as walls or external walls as you will definetly have someone try to paint over these, inlcuding painters with water based acrylics. I would however consider this for internal cupboards and woodwork but is a bit over-kill. I have also painted over tiles using a single- pack etch primer or 2 pack epoxy primer + polyurethane topcoat, inlcuding wet areas and lasts ages and glossy. You have to ensure tile surfaces are clean, preferably lightly sanded or use hydrochloric acid to etch.
