FAQ TK64 Trailer Floor Coating

If aluminum is new or fairly new: metal could have a light oily coating from the manufacturing process. Clean with a citrus based degreaser, rinse thoroughly and dry. Scuff with P120 sandpaper, dust and ready to apply. If aluminum is old: it already has been scuffed by using it but now the cleaning is very important.  Dirt will have accumulated in those scratches and will hinder good adhesion of the coating. Clean the floor with a citrus based degreaser and a stiff bristle brush and/or power washer. Rinse thoroughly and dry.

Pay attention to the application temps (min 60F/ max 90F ) . Do not apply in full sun.

Yes, but make sure that the wood is not freshly treated and still wet. On trailer floors that is not an issue but if you use it on other treated wood, the wood at hardware stores is sometimes still wet. Let it dry for several weeks before application.

If done properly, spraying underneath the trailer with foam should create a water/air tight seal.
By coating the top of the floor with TK64, you will create a similar seal on the top. The plywood will stay perfectly dry, protected from the elements  and there is no need for it to breathe.

TK 64 is not a paint, it is a thick coating that will effectively seal the plywood.
If you decide to apply TK64, ensure you caulk the edges, where the plywood touches the frame or side walls.

Color of Spray Foam
If black foam, you are good to go.
If yellow, beige or light green, you might consider putting a protective coating over it because some of the foams are not really meant to be exposed to the elements.

Our coating is basically a protective plastic barrier that is strong enough to withstand the abrasion of rubber boots, muddy tires, tool boxes etc.

When it comes to sharp , metal objects however, this impermeable protection can be damaged. I have seen the damage that snowmobiles can do on inch thick rubber mats protecting some wooden bridges and TK64 would fail there also.

I would suggest that you paint the floor with TK64 and install a rubber mat on the critical areas where the snow mobile could cause damage. That should give you the desired protection for many years to come

Yes, you can apply this coating directly on the Advantech board after the board has been cleaned with a Citrus based degreaser (ie ZEP, Orange Blast, etc).

Make sure to scrub the surface properly and rinse with lost of water.

Let the board dry before application.

When engineering this product line , we had the environment in mind.
Although each municipality has different regulations , most adhere to the following rule.:
As with Latex based paints, open old/empty containers and let the remaining contents dry out. If your city recycles plastics separately, it can be recycled as such. If not, it can be added to the regular garbage .

Except for plastic, this coating sticks to almost anything BUT oil spots are definitely a problem. Best use a citrus based de-greaser, full strength , let it sit for a while , rinse and repeat a couple of times.

If available use power washer on those areas. Let dry and then apply two coats. If the coating still does not adhere, you can cut the problem spot out, de-grease again. I had an area in my trailer soaked through the floor. I just replaced that part of the floor.
How to Clean Used Utility Floors

Short term exposure to gas is no big deal. A spill while filling a tank will quick evaporate and do no harm. If gas sits on the coating for a couple of hours , the coating will get softer. Gently remove the gas and air out the trailer. The coating will harden again.

Yes! A lot of trailer owners cover the bottom 6 or 12 inches of the walls for extra protection.
A word of caution, however, better not to cover the entire height of the walls. This coating has anti slip compounds in it and will feel  rough when hit by bare skin.

"It mentions not applying in humidity over 80%, but cooler than 90°. I live in Florida so the days are well over 90°, so early morning would be best for temperatures. The problem is in Florida the humidity is also well above 80% even in the early morning. How can I get around this? "

The only negative effect the Florida humidity will have on your application is that the drying time will be longer than indicated in the Coatings Tech Sheet. So you will have to wait an hour longer before applying the second coat and wait at least 24 hours before light use. You can always help the drying process by using a small fan to move the air.
But do not apply in full sun exposure. Then the coating would dry too fast.
