Monstaliner?

[Outoforder]

So I used rustoleum bed liner on a foam box I made and it seemed ok. The foam box was foam, primer, glue, canvas.

I asked monstaliner about using this on a foamie and they said it would melt the foam

Has anyone tried monstaliner on their foamie?

Besides chemistry compatibility issues, I reckon anything that rigid would end up with stress cracking.

Skin-only panels supported by a rigid frame are one thing

but with foamies there is little such support, the box as a whole needs to flex under stress

It worked because you didn't put it directly on the foam. Glue canvas and primer protected the foam. This is a flexible bed liner correct? It should holds up rather well as long as the adhesion to the substrate stays intact.

My point is that the stresses imposed on a much larger box going down the road at highway speeds, plus maybe in high winds sometimes, semitrailers opposite etc

will demand large deflection/recovery flexibility.

The bedliner may be "somewhat flexible" but I reckon different enough that the tensile / adhesion of the outer eggshell layer will be stressed too much resulting in cracking.

None of which has to do with the chemistry compatibility issue.

And I fully admit I could be 100% wrong, seem to recall some bedliner product protecting a watermelon dropped off a high tower onto concrete, shell intact fruit smoothie inside.

I suspect great variability between brands / formulations.

The people at Durabak claim that their product can be used directly over foam. I have used their products on metal and wood but never over foam.

Outof'… Just Curious … “ The foam box was foam, primer, glue, canvas. “ What kind of “Glue” … ???

[John61CT]

Interesting, lots of threads mention that brand (not necessarily foamie ones though).

I see repeated comments in many places remarking on its flexibility.

I wonder if the smooth version would do as "all in one" eliminating separate glue + primer, then once foam+fabric full encapsulated, switch to the rough texture if desired.

Yes you can put it directly on foam since it's polyurethane based and probably be better off letting it be the alter version of pmf with direct adhesion to the foam. It's kin to gorilla glue with rubber particles added.

Be sure to test thoroughly before putting that idea "into production".

Adhesion might be fine, presumably waterproof so long as the skin doesn't crack, but tensile strength, ability to truly saturate into the cloth not just encapsulated, many other success factors

are wildcards at the moment.

If it is rubbery durable and sticks directly to foam why even use canvas? You have a semi rigid shell directly on the foam which gives much higher stress loads than canvas. Test it and if it sticks and is durable this is a big win. The beauty of this part of the forum is looking for alternate ways to encapsulate foam balancing strength cost life and ease of building.

The added tensile strength, against forces pulling and pushing both laterally and perpendicularly to the wall plane,

Imagine embedding tough mesh screening. . .

[linuxmanxxx]

Screen I could understand but canvas and this I believe is counter productive. The whole purpose for canvas and the saturation is stiffening of the canvas shell. It works because of the saturation but the delamination issues and having to iron it to recover are because of poor adhesion to the foam. If this stuff has pure adhesion and hardens to a shell you've replaced the canvas with a one step covering.

I'm a wood guy, but I can tell you this; Monstaliner is a great finish. I applied it over primed fiberglass and it takes 2 gallons to do a 5'-wide teardrop. That's $400.



That may send you in a different direction.

Monstaliner directly on foam no durabak directly on foam yes. Whoever has some, please test it directly on the blue or pink foam. I've been very interested in the water based plastic coatings but this sounds very intriguing.

I know the pmf route is a value thing but it's very time consuming. If an alternative is 30% more cost but saves half the time or more and adds maintenance free that's value indeed.

I am Very close to Spraying 2 Colors of Monstraliner on my flat back; BUT

I am on another project digging with the web and found this, for the foamies
Not gona try it; but hope someone digs into it.
