Peel and stick floor tile sealer

A sealer will not address an adhesion issue.

The way you asked the question it sounds to me like you have some loose tiles?

Yes !

That exactly what is going on. Brand new peel and stick flooring and we have not even used the camper yet, still working on it .
It’s lifting up in areas because of the sun.
Any suggestions.

I was thinking maybe squeezing some contact cement under the tile and putting a weight on it.

Wife is not happy about this product. She spent a good amount of a weekend laying down the floor to have it lifted.

The interior of a camper/travel trailer is a very harsh environment. The temperature swings are far more than in any home. It can be "below freezing" because we see many frozen and broken water pipes. A closed-up trailer in the hot desert sun could see 150 degrees of interior temperature. No home ever sees a 120-degree temperature swing.

Combine the temperature swing with the swing in humidity from a rainy cold Oregon coast, to the hot dry (no humidity) of a Southwest desert, and you have the one/two punch.

The third punch is that the door is usually "always open" and you have direct sunlight with a very high surface temperature. Peal and Stick anything is not manufactured for these extreme conditions. It's just the wrong product for this application. Sure, some get by with it, but far more fight with these lifting or moving problems

My guess is you need to do some more investigation and see if the adhesive is separating from the tile, or the subfloor. If the adhesion problem is that it's lifting from the subfloor, I would lift the tiles by maybe two rows at a time a reglue them to the subfloor with normal commercial tile glue. But if the separation is between the tile and their original stick'em glue, I would replace the entire floor tiling because you will likely never get all of the stick'em off and every time they get warm, they will lift.

While we are talking "doom and gloom" be aware that todays cost for quality tile adhesive is crazy. I pay close to $100/gallon for the glue I use on my new Marmoleum sheet floors.

Contact cement as the name implies, has to be applied to both surfaces, allowed to fully dry "before" you stick the two surfaces together. I do not believe Contact Cement will give you a satisfactory solution to the problem.
