FRP is a finish system, not just a sheet product. A wall can have the correct panel color and still fail the project intent if the substrate is uneven or damp, the adhesive is incompatible, joints cannot move, penetrations are unresolved, or equipment blocks the required installation sequence.
This checklist helps owners, general contractors, architects, facility teams, and trades create one coordinated scope. The selected manufacturer's current documents, approved plans, specifications, governing requirements, and responsible design professionals remain controlling.
Start with a room-by-room finish schedule
- Room name, elevation, wall dimensions, ceiling height, and panel termination height.
- Exact manufacturer, product, series, thickness, texture, color, fire-test classification, and approved substitution status.
- Full-height panels, wainscot, ceiling panels, liners, or another layout.
- Exposed corners, inside corners, bases, caps, openings, columns, soffits, and transitions to tile, stainless steel, paint, or another finish.
- Required samples, mockups, seam layout, color acceptance, and retained attic stock.
Accept the substrate before material is installed
| Substrate question | Record | Resolve before installation |
|---|---|---|
| Material | Gypsum panel, concrete, masonry, plywood, existing finish, or another approved surface | Compatibility with the panel and adhesive system |
| Plane | Flatness, joints, fasteners, patches, offsets, and corners | Who corrects conditions that could telegraph, bulge, or prevent full adhesive contact |
| Surface | Cleanliness, paint, sealer, grease, dust, gloss, or residue | Required preparation and test area |
| Moisture | Water source, drying record, concrete or masonry condition, and room humidity | Source correction and manufacturer-approved limits |
| Temperature | Room, panel, adhesive, storage, and acclimation conditions | Temporary or permanent HVAC responsibility |
Crane Composites' installation information directs teams to read the full instructions, store panels flat indoors, and control environmental conditions. Its technical data also warns that uneven concrete block may contribute to delamination or bulging. Use the current guide for the exact product rather than applying one generic detail to every FRP panel.
Coordinate adhesive, trim, and joint movement as one system
- Named adhesive, spread rate, trowel, open time, working time, cure conditions, and substrate limitations.
- Panel expansion spacing at edges, joints, floors, ceilings, openings, and penetrations.
- Moldings, sealant joints, butt joints, welded seams, rivets, fasteners, or another selected joint treatment.
- Inside and outside corner profiles, division bars, caps, base conditions, and termination at dissimilar finishes.
- Sealant manufacturer, color, tooling, substrate preparation, compatibility, and cure time where sealant is specified.
Freeze penetrations and mounted equipment early
Create an elevation showing every pipe, conduit, outlet, switch, box, cleanout, access panel, hand sink, dispenser, shelf, guard, hood, cabinet, equipment anchor, and wall-mounted accessory. Mark whether the item is installed before or after FRP and who provides blocking, sleeves, escutcheons, sealant, and final attachment.
- Do not let field crews discover that a preinstalled sink or cabinet blocks the planned panel and seam layout.
- Keep panel joints away from openings where the approved system or project details require it.
- Confirm heat-producing equipment clearances with its manufacturer and the FRP manufacturer.
- Coordinate food-service, health, accessibility, fire, plumbing, electrical, and sanitation requirements with the responsible parties.
Plan sequence, access, and protection
- Complete concealed rough-ins, backing, inspections, and required tests.
- Finish and accept the substrate to the level required by the selected FRP system.
- Provide approved storage and acclimation conditions.
- Lay out panels, seams, trims, penetrations, and cuts against the accepted elevation.
- Install panels and accessories under the product's environmental and adhesive limits.
- Protect the finished surface from later trades, equipment installation, heat, impact, and incompatible cleaners.
Define a measurable closeout
- Walk the work under the room's normal finished lighting.
- Check panel layout, secure adhesion, seams, trims, corners, penetrations, sealant, scratches, bubbles, and finish damage.
- Record approved repairs and the acceptance boundary for each room.
- Provide product data, cleaning instructions, adhesive and sealant records, warranty information, color and lot information, and attic stock.
- Document which moisture, equipment, or maintenance conditions can affect performance.
Use one scope sheet for every bidder
List square-foot and lineal-foot quantity bases, room elevations, selected system, substrate preparation, trims, sealant, penetrations, access, protection, schedule, testing, closeout, alternates, and exclusions. Ask every bidder to mark the same lines included, excluded, allowance, or by others. That reveals whether totals actually describe the same finished installation.
