Mixing LO/MIT Radiant Barrier Paint

Agitate LO/MIT thoroughly before and during use for best results

LO/MIT is a premixed, one part system. It is supplied ready to use. No thinning or tinting is suggested or recommended. LO/MIT is heavily pigmented. Agitate thoroughly prior to and as frequently as possible during installation to disperse pigmentation and keep it in suspension. LO/MIT may be applied with rollers in some cases (coverage rates will suffer), however best installation practice is with a standard airless paint sprayer. For smaller areas, air atomization equipment can also be used (25-35PSI).

For airless equipment, remove filters and utilize a self-cleaning 6-13 spray tip. Set pressure level as low as possible for best coverage rates and results. Properly mixed, LOMIT’s viscosity is similar to water. LO/MIT should be applied at roughly 1 mil wet (0.001in) and will dry to less than half that (LO/MIT will change the color of the substrate, but it should still show surface characteristics, like wood grain lines). A second coat or thicker application will not yield better optical properties. Coverage on most surfaces should yield around 400 square feet per gallon sprayed.

Spray area should be as well ventilated as possible and operators are suggested to wear goggles, carbon filter respirators or masks, gloves and disposable or easily cleaned full body covering during application. Ambient and substrate temperature should be above freezing for application, the hotter it is, the quicker the coating will cure.

Spraying under roof requires minimal surface preparation. Be sure substrate is dust and cobweb free. Sidewalls and garage doors should be free from dust, oils and greases. For agricultural buildings, please visit Commercial applications for more information. Rooftops and exterior surfaces should be pressure washed and dry, please visit Roofing applications for more information.

LO/MIT Installation logo 3When applying to the underside of roofs, spray the entire radiating surface, including all three exposed chords of the rafters (unless other insulation products are also going to be added into the rafter space – see below). Support beams are not necessary to cover, but coating sidewalls and gable ends will offer additional heat protection. Roof sheathing may also be pre-coated while still on the ground and stored (painted sides together) for future use. Be sure to drop cloth or remove items from attics. Turn off any power ventilation while spraying. Avoid spraying outlets and light fixtures. LO/MIT is electrically non-conductive, so covering wiring is not a problem. Do not spray through soffit, ridge or gable vents.

LO/MIT-I will skin dry within one minute after application. Full cure will generally occur within 15 minutes to 1 hour depending on ambient temperature and humidity. LO/MIT-II will skin dry within 5 minutes after application. Full cure may take from several hours to several weeks, depending on ambient temperature and humidity conditions present, so avoid contact and abrasion during this time. LO/MIT-II MAX will skin dry within 10 to 15 minutes after application. Full cure may take several weeks to six months or more depending on ambient temperature and humidity conditions present. Abrasion is typically not an issue on the underside of the roof, but the slow ambient cure of LO/MIT-II MAX should be kept in mind when building sidewalls or garage doors are painted. LO/MIT-II and LO/MIT-II MAX are water-soluble and are NOT recommended for any exterior applications

Clean up LO/MIT-II and LO/MIT-II MAX and sprayer/lines with soap and water. Isopropyl alcohol can also be used if necessary. LO/MIT-I should be cleaned with a strong solvent like xylene, toluene or acetone. Be sure to review your sprayer’s compatibility with solvents before using LO/MIT-I. Contact the factory to request MSDS information.

To be effective, LO/MIT (and all radiant barrier technologies) MUST face a minimum two-inch airspace. It cannot be sandwiched between two different substrates. Insulation directly adjacent to the LO/MIT surface (blown-in insulation or spray foams) should be backed off using baffle air channels. The LO/MIT surface may not be painted over, tinted or adjusted in any way.
