house painting

My career as a home improvement contractor began as a painter and now my companys painting divsion does about 20 jobs a year. I have used all magor brands of paint available .The two magor brands that i use are sherman williams and benjiman moore paints. And the truth is I use these paints the most becuase they market well. I can look back now 8 years at sme work and can see that jobs done with cheaper brands like behr and valspar may actually be doing better.
I am sure this is not the first time you hear this but preperation work is is the key to a long lasting paint job. and further more cheap wood right form the lumber yeard will not hold paint as well as higher grade wood , for instance #3 pine vrs #4 in the long run you will get what you pay for. YOu can also scarape and sand wood untill your hands fall of but but if that wood is not dried properly , you can be pretty much assured that once it is coverd by paint it never will be. weather conditions are a very big deal when it comes to exterior painting , but even inside paint will not dry or look as good as it could if it is to humid or cold. any weather dry sunny and between 60 to 80 degrees is about perfect. you could paint over almost compltly unprepped siding with a good quality paint in this weather and it will probly last 3 times longer than if you sanded it to bare wood and painted the bare wood when it had moisture in it, Of course i do not recomend sloppy prep work. nor would i recamend forgeting the primer even when the can says self priming, And lastly the next time you read the warrentty of any brand of paint try to keep a sense of humor about it , and realize that six years ago really was a lifetime..
