Invisaflects Refrigeration Trailer Coating Instructions

This is a short manual for the application of Invisaflects coatings on the inside and outside roof of a refrigeration trailer. There may be differences in trailers that could require some investigation regarding preparation of surfaces prior to application. These instructions are based on field application of our products on a 53-foot aluminum body refrigeration trailer.


Items you will need on site:

2 buckets of Invisaflects White LightScene

1 bucket of Invisaflects Reflective Roof Technology

1 gallon Cromax 225S Aluminum Metal Cleaner (This and 226S can be bought at auto paint suppliers like National Coatings and Supply)

1 gallon Cromax 226S Aluminum Conversion Coating 1 container of Dawn Dishwashing liquid

  1. commercial sander or hand sanders and enough 80 grit sand paper for 450 sq. feet of sanding 2 floor mops

  2. large sponges with scratcher pad side 2 packages of shop clothes

15 rolls of 7 mils clear plastic long enough to drape the side of your trailer 5 rolls of high quality masking tape that is water resilient

Outdoor lighting or head lamps if working into night time hours Rollers (1/4-inch nap), Brushes, or Paint Sprayer

Paint trays

Ladder big enough to reach top of trailer

Leaf blower (gas power is faster than electric because of not having to deal with a cord) Pump type garden sprayer


Drop cords sufficient to reach your trailer roof Bucket for clean water

Safety glasses Respirator style air mask Water proof gloves


Camera/Smart Phone






Pre-Application data collection

One of the most helpful sales tools is to find out the cool down time for this trailer before coating. So, if you can have the driver or someone run a cool down test the day before coating, recording both the outside temperature and the number of minutes it takes to get the trailer down to 25 or 35 Fahrenheit. Later after coating you will run the same test and record the data. Along with this data it is good to take pictures for before and after presentation.



Ideally two workers are going to attack this job and complete it in one full work day. This is not accomplished by working slowly. You must hustle. You should start very early in the morning at the break of dawn.

Draping the sides of the trailer with the plastic should be the priority before starting to sand or paint. One person should be on top to tape and one down below to help stretch and attach the plastic. You shouldn’t need to drape over the refrigeration unit on the front which will allow you to run the unit for faster drying inside the trailer by running the unit on heat.

Once the trailer is draped, the big picture is for one worker to attack the inside of the trailer while the other attacks the roof preparation.

The inside of the trailer requires very little preparation unless the walls or ceiling are extremely dirty. If the walls are dirty, then they need to be degreased and sprayed using a mop, Dawn soap and a hose. A clean surface allows the coatings to adhere properly. Dry with leaf blower and Refrigeration unit on heat as needed.

If cleaning is not necessary, then the inside walls and ceilings can be coated with the White LightScene immediately once you tape off any areas you don’t want coated. The more surface you cover inside the trailer, the better insulation results you will achieve. Metal bars or supports are very conductive to heat so coat them as well. The inside is simply coated with two coats of White LightScene either by Sprayer, Roller, Brush or some combination thereof. Running the refrigeration unit on a high temperature after the first coat will speed up the dry time if necessary. With a sprayer, the entire inside can be coated twice in only an hour of total labor. Once the inside is done, the second worker can move to the top of the trailer to help with that process.


Meanwhile, the second worker should be roof top cleaning the surface with dawn soap and mop. This can be a lot of scrubbing and you may need to get on hands and knees to scrub with sponges, rags and scratchers. Plan on getting wet.

Once the top of the trailer is clean, the wet sanding process begins. Wet sand the entire top of the truck. Wet sanding keeps the sand paper from gumming up in the process. The main idea is the rough up the surface so that the coatings will adhere properly.

After the top is completely sanded double check your work by rinsing and checking for any missed places.

Dry the top with your leaf blower.

With your garden sprayer apply per instructions (get these printed out when you buy the cleaner) the 225S metal cleaner to the top of the roof.

Rinse and dry the top of the roof with your leaf blower.

Next apply the 226S Aluminum Conversion with your garden sprayer per instructions to the top of the roof.

Rinse and dry the top of the roof. The roof is now ready to coat.

Apply one coat of White LightScene to the top of the roof. This will should be dry enough to recoat by the time you get to the end of the trailer.

Next apply one coat of Reflective Roof Technology over top of the White LightScene. The roof is done.

Once you have completed the entire truck you will need to remove and dispose of your plastic draping.

At this point you can show off the technology by having the operator of the truck turn on the refrigeration unit and cool the truck down to the same temperature as they did the day before. Then clock the cool down time. This will give you a very good idea of the percentage of savings they count only simply from a faster cool down. Remember to take pictures of your finished work!
