10 years and 500 houses later I still in business and not a 1 failed house yet from a 1 and 1 system.
I have seen hundreds of new houses painted in my area on the east coast. The best system is 1 coat of either oil or acrylic primer and 2 coats of acrylic semi-gloss finish paint on wood trim. We don't have alot of stained houses here but do have alot of concrete siding with painted trim of either pine or fir. If there is not a enough film build, mildew will grow faster if the conditions are right and it does not have to be in the shade or moist areas as I have seen it grow on the south side of many houses. The better system on the concrete siding is a coat of acrylic primer and a coat of either acrylic semi-gloss or satin house paint.
I have been in the business for 27 years and know from experience that on new work 3 total coats is better than 2 any day. It is the difference between a 3 to 4 year job and 6 to 7 year job. Now there will be paint on the house way longer than this but it will be so broken down as to cause problems down the road. Also people need to check over their houses every spring and fall for problems of cracked paint or loose caulk and take care of those little things then and the total paint job will last longer.
Have a great day.
Putting on two top coats effectively doubles the amount of mildewcide - and once it is gone provides twice the amount of paint to stand up to weather and the environment.
That is the most stupidest thing I have heard yet as to mildewcide coming out and lasting longer with 2 coats,WHAT does 1 coat have to go away before the other will work?
NO it will leech out at the same time just in a higher quanity,giving you better protection in the same amount of time just in greater #'s.Are you a working painter MR.Paint or just a handy man?Because it sounds like advice you would read off the can rather than a hands on experinced person.
I would like to see anyone else give written warranty on the work they have done on any kind of home,we stand behind all of the work done as long as prep has been done by us.
10 years with no call backs other than staining log siding and additional work other than the orginal must be doing something right.
I have been in the business 18 years - making paint - selling paint - painting.
Any written warranty work I have ever done (where the paint company supplied the warranty) was done with two coats. No paint company I know will write a warranty on one.
In any case - it sounds here like we should agree to disagree on this one. We all give some good advice - and we all have our little things we know from experience or training - so - I am done posting on this one.....
See you all on another thread!
So now I am done with this.
