Installing  LOMITlogoeffects-300x121Attic Heat Barrier?

Here’s what you need:



  • Hand drillHand Drill
  • Spray tip (SIZE 13 OR 15, reversible/self cleaning)Spray Tip


  • Garbage bags
  • Painter’s masking tape
  • Extension cord(s)
  • Wet wipes
  • Extra plywood pieces to use as movable flooring (if needed)


Here’s how to prep:

  • Make sure roof temperature is above freezing
  • Turn off powered ventilation and all HVAC equipment
  • Drop cloth attic flooring, pathway into & out of attic space
  • Drop cloth or remove personal items in attic
  • Sweep away dust/cobwebs (if necessary)
  • Mask outlets/fixtures with painter’s tape
  • Remove filters from paint sprayer (optional)
  • Test-spray water through sprayer & adjust pressure. LO/MIT has a similar viscosity to water
  • SET PRESSURE AS LOW AS POSSIBLE to get a mist to land on the surface. There should not be any pooled liquid running down the substrate. Lowest pressure setting also minimizes airborne particulate/wet fall and helps extend coverage rates
  • Practice on scrap plywood/OSB to get comfortable before spraying roof
  • Close attic access for installation to be sure odor stays in attic

Here’s how to install:


  • Remove lid
  • PRE-MIX 2-3 MINUTES prior to usage to disperse settled material
  • No thinning is required or suggested
  • Insert sprayer intake into LO/MIT bucket
  • MIX AS YOU GO, use constant agitation to keep LO/MIT distributed


  • ONLY APPLY ONE COAT, it’s all you need for LO/MIT to work
  • Evenly spray the entire roof surface including rafters, truss members, sidewalls, gable ends – spray tip should be about 12in away from surface and as perpendicular to the surface as is reasonable
  • LO/MIT is thin! Wet film thickness should be about 1mil (0.001in) and the coating will dry to about a quarter of that. You should still see all the grain characteristics in the wood, but everything should be silver – no wood color!
  • Coverage should be about 2,000sqft per pail (400sqft/gal)
  • Spraying electrical wiring is ok, but avoid light fixtures and outlets as well as soffits, ridges or gable vents that could get LO/MIT on your home’s exterior
  • Start with the peak of the roof and work your way toward the eaves. That way if you run out, the warmest parts of the roof have been coated first
  • Check your work! Be sure to review all sprayed areas for full coverage before cleaning up – Shine a light around and touch up any thin areas

Here’s how to clean up: 

  • Run hot water/soap through sprayer to clean intake/hose/gun
  • Clean tip/extension wand with soap & hot water
  • If empty, wash 5-gallon container with soap & hot water and recycle
  • If not empty, re-cover and store up to one year in cool place for future use
  • Remove gloves/coveralls/booties & dispose
  • Remove drop cloths & launder or dispose
  • Wash goggles and remove & replace respirator filters
  • Wash hands and face (or use wet wipes), launder clothes, get a shower

Odds & Ends:

  • Turn on power ventilation/HVAC only after all airborne particulate has settled
  • Vanilla scent should dissipate within 24 hours, depending on ventilation
  • If the smell permeates into the home or is bothersome, open all windows to aerate the house for as long as necessary – LO/MIT is low VOC and non-hazardous.
  • LO/MIT may take a few weeks to fully cure, but starts working right away. Curing is time, temperature and humidity dependent
  • Be sure to leave a 2” AIRSPACE if you install any other insulation down the road! LO/MIT CANNOT BE SANDWICHED between two solid materials or it will not function thermally as intended. LO/MIT CANNOT BE OVER-COATED by another paint for the same reason
