FRP is not one white sheet

The color question is really a fire-class question

Ask for a color first and you can spend a week liking one you cannot have. The manufacturer publishes fifteen colors in the embossed texture, and a job specified to Class A can have six of them. Class C opens the rest — black, pineapple, red, bordeaux, blue, the greys and browns.

So the order that works is: find out what the room has to meet, then choose inside what is left. It costs one question at the start and saves a re-selection at the end. The palette on our FRP page is laid out that way on purpose, class first, because a page that prints colors in a flat row invites exactly the mistake.

Sizes narrow it again, and not always predictably. Not every color runs in every size, and the longer sheets are a custom order. One worth knowing early: textured beige does not run in the 9 ft length.

Where a color is doing work, not decoration

Black FRP is the clearest example of a color that is a functional choice. It goes behind bars and around slop-sink areas, where a white wall shows every splash and never looks clean no matter how often it is wiped. It turns up in grocery too, behind floral and in display cases, where the wall is meant to disappear behind the product rather than compete with it.

Pineapple sounds like a novelty until you see where it is used. We supply it for a grocery application where that color is the point. We are not going to name the customer, but it is a reminder that the loud end of the palette exists because somebody specified it for a reason.

That is the argument for breadth generally. A supplier with two colors will tell you the job needs one of those two.

What is behind the sheet changes what you can fix it to

Sheet FRP goes onto a solid surface — troweled onto gypsum or plywood with an adhesive, or dropped into a ceiling grid. If the wall behind it is not solid, the sheet is the wrong form of the product and no amount of adhesive fixes that.

The alternatives are laminations. Fiberglass on a fluted core spans framing, so it fixes to studs, joists or furring strips as well as solid surfaces. Fiberglass bonded to waferboard or plywood brings its own backing. The same fiberglass face also laminates to an aluminum honeycomb core where a job wants more stiffness for the weight.

We laminate to drywall, OSB, plywood and foam depending on what the job is. The question we ask is never which panel you want; it is what the room does, how it gets cleaned and what it is built of. The panel follows from the answers.

A panel job is finished at its edges

The part most often left until too late is the trim. Corners, division bars, caps and base are what turn sheet goods screwed to a wall into a finished surface, and they come in the same color range as the panels, so they can disappear into the wall instead of outlining it.

Vinyl covers most of it, in profiles for panel thicknesses from .090 sheet up to 2 in. foam. Aluminum is there for the corners that take a beating — a loading bay, a wash-down aisle, a door reveal in a kitchen — and is rated for exterior as well as interior use.

It is worth pricing the trim at the same time as the sheets rather than discovering the corner detail after the panels are on site.

Why we keep saying specialist

Fifty-four years in one product category is long enough to have seen most of the ways it goes wrong: the color that could not be used, the sheet fixed to a wall that could not take it, the corner nobody costed. None of that is complicated. It is just specific, and it is the part a catalog cannot tell you.

Tell us the room and what it has to survive. The specification is the easy part after that.
