Spray painting with Hy-Tech insulating paints or your own paint using the Hy-Tech insulating ceramic additive is basically the same as we discussed in spraying techniques Part 1 and Part 2
The most important thing to remember is to remove ALL the filters from the spray unit. There is normally a filter in the gun handle and some guns like Graco brand also have filters in behind the tip. The large filter screen on the dip tube that goes into the paint is fine and you can leave it in place.
Spray Painting Attics:
When you rent your spray unit pick up an 18" extension wand for the gun with a swivel head. This makes spraying attics much easier.
Most all ceramic reinforced coatings will need to be thinned, use up to 1 pt per gallon. I recommend when spraying the attic radiant barrier that you apply two light coats, one in one direction and follow up with a crossing coat in the other direction. Spray the back side of the gable ends too.
I also spray the air conditioning ducts for added insulation. Avoid spraying light fixture and other electrical boxes, remember Hy-Tech radiant Barrier Paint has real metallic aluminum in it and it will short out electrical connections!
In order to keep the overspray to a minimum avoid pulling the trigger unless it is Pointing at Something! If it is pointing into the air guess what, you just filled the air with paint. By using the least amount of pressure required to produce a nice even fan and making sure you always trigger when pointing at a surface with your hand in motion you will have very little overspray in the air. Use the swivel tip when reaching out near the edge of the roofline, No need to try and paint the area that extends out over the exterior wall.
Spray Painting Ceilings and Walls:
Everything is the same as spraying conventional paint with the exception of removing the filters and thinning the paint due to the fact that adding ceramics does thicken the paint some. Adding Flame Guard Fire Retardant to the paint will also thicken the paint and will require a little water to thin it so that is spreads uniformly. I use a .024 tip for most all spray applications.
On ceilings spray up next to the wall/ceiling joint and work your way out towards the center. Use the cardboard shields I discussed earlier in
Part-2 and keep that bucket of fresh water handy!
