Primed Boards and Shelving
S4S boards for trim and craft work, from 1×2 to 1×12, plus bullnose shelves, closet cleats and hook strips. Primed MDF or finger-jointed pine, cut to the lengths on your order.
In the room
Boards, shelves and a hook strip in a mudroom nook
Primed S4S 1×4 boards case the opening. Inside, a bench top and a bullnose shelf rest on cleats, and a hook strip carries the coat hooks.

In the US, S4S boards are sold by nominal size. A 1×4 is 11/16″ thick and 3‑1/2″ wide; the table lists the others. Thicker boards, 1‑1/4″ thick, are made too.

How it’s made
See how primed boards and shelves are made
Pick a board and follow it through our line step by step, then take it apart to see the MDF core, the gesso coat and the primer.
Drag to turn it
The 3D view is not available in this browser. The steps below describe the same process.
-
MDF board is ripped into strips as wide as the board.
-
A moulder planes all four sides and eases or rounds the edges: a bullnose on shelves, a round-over on cleats.
-
A thin gesso coat goes on through a die shaped like the section, over the face and both edges.
-
The gesso is dried and sanded smooth along the whole length.
-
A white primer coat finishes the board. It is ready for the final paint.
Illustration. The sections are common profile types drawn at typical sizes, not a catalogue; every profile is shown at about the same width, and the coats are drawn thicker than they are.
Materials
Primed MDF or finger-jointed pine
Both come primed white, ready for the final paint. Tell us which one your market expects, or order both in the same container.
Primed MDF
Smooth and stable, with no grain to show through the paint. MDF boards get a gesso coat and a white primer on our coating line.
Finger-jointed pine
Clear pine blocks, cut free of knots and finger-jointed into long lengths, then moulded and primed white. Real wood for paint-grade work.

Send a drawing, a sample or a photo with the main sizes. We make the profile from it and send you a sample to approve before production.

Ordering
Boards in the same container as the rest of your order
- Send the profiles: a drawing, sample or photo for each one, with the material, lengths and quantity.
- Approve the sample: we send you a sample, and production starts once you approve it.
- Production: the lead time for custom orders is 15–30 days.
- Loading: boards and shelving can share a container with mouldings, casings, skirting and wood-based boards. The minimum order is one 20ft container, and it is negotiable; the quantity of each profile follows your order.
We cut every profile to the lengths on your order. The quotation gives any tooling or sample cost and the packing.
