A little while back I wrote a post about Sherwin Williams having a thermal barrier paint called E-Barrier. I decided to start my attic upgrade with this product. There are plans to seal up and increase the insulation up there, but to do this project without knowing where to step would probably double the time it took.
|5 gal. Sherwin Williams E-Barrier Paint||$176.00|
|Paint sprayer rental||56.00|
The person at Sherwin Williams didn’t want to shake the paint at the store because he didn’t want the aluminum in the paint to create a static charge. Instead I flipped the paint the day before to get all the particulates to the top of the bucket. The day we painted I used a drill and paint mixer for 5 minutes to incorporate the particulates and latex.
- Pressure: 2000-2500 psi
- Tip: .017″-.021″
The one I rented from Home Depot had an Airlessco 517 tip on the sprayer. According to Airlessco’s site this is a .017″ tip.
Preparation for the area included laying down some plastic I already had to protect the carpet, emptying the closet, donning a paint ventilation mask and putting on the painters suit.
Our house has two joined attic areas. The first one has all the duct work from the two A/C units on the roof.
I did a horizontal application pattern with some overspray.
It took about an hour to apply the paint to about 500 sqft. of attic space. One thing to remember is to stay hydrated when working in the attic. It was at least 10-15 degrees warmer than it was outside.
The second attic space over the master bedroom has more room to maneuver but there is more electrical work to watch out for.
The second attic area took another hour to spray. I learned a couple of tips from the first attic area:
- Switch to spraying vertically near the bottom truss
- Keep the spray gun 8″-12″ away from the target area
- Use the camera to help identify where some areas were missed
