Making a Slate Chalkboard for Kitchen Menu Planning

Why Slate Suits a Working Kitchen

Slate has been used for roofing, flooring and worktops for centuries, and for good reason. It is dense, non-porous when properly finished, and naturally resistant to stains, heat and moisture — all of which makes it a superb candidate for a kitchen chalkboard. A slate menu board will not buckle in a steamy room, it wipes clean with very little effort, and it ages gracefully rather than looking scuffed and tired after a year of daily use. It also has a quiet, mottled beauty that suits both traditional and modern kitchens, whether you hang it against painted plaster, tongue-and-groove panelling or a tiled splashback.

If you are making your own, the standard approach is to take a piece of natural slate and give it a chalkboard finish, either by leaving the cleft face bare or by applying a coat of chalkboard paint for a deeper, more uniform black. Both work. Bare slate offers texture and character; painted slate gives you a smoother surface and a crisper line for writing. Many makers do the latter because it produces a more dependable writing surface, especially for finer lettering.

Choosing and Preparing Your Slate

Look for slate around 8–10mm thick. Anything thinner tends to flex and can crack when drilled, whilst anything much thicker becomes unnecessarily heavy on a plasterboard wall. A board roughly 40cm by 60cm is a comfortable size for a weekly menu plan and weighs a manageable 2–3kg. Check that the piece is flat and free from deep delamination; a little natural variation in the cleft is fine and adds charm, but flaking edges will only get worse.

Preparation is where most homemade boards succeed or fail. Work through these steps:

• Wash the slate with warm water and a drop of washing-up liquid to remove dust, grit and any lingering quarry residue.
• Scrub with a scouring pad, working across the grain of the cleft rather than along it, so you do not lift flakes of stone.
• Rinse thoroughly and leave to dry somewhere airy for a full 24 hours. Trapped moisture under paint will cause blistering later.
• Lightly key the surface with 120-grit sandpaper. You are not trying to flatten the slate, only to give the paint something to grip.
• Wipe away all dust with a damp cloth, then a dry one, and let it dry again.

Top tip: mask the edges with low-tack painter's tape before painting. Slate chips easily, and a clean edge makes the finished board look intentional rather than improvised.

Applying the Chalkboard Paint

Use a good water-based chalkboard paint and stir it thoroughly — the flattening agents settle quickly, and an unstirred tin gives a patchy, shiny finish. Apply the first coat thinly with a foam roller or a soft brush, working in one direction and avoiding the temptation to load it on. Thick coats trap solvent, dry unevenly and leave ridges that show up in raking kitchen light.

Leave it to touch-dry according to the tin, usually two to four hours, then sand very lightly with 240-grit to knock back any nibs. Apply a second coat at right angles to the first, and a third if the slate's colour still shows through. Two coats are usually enough on a dark slate; three give a properly opaque black. Once the final coat is on, leave the board undisturbed for at least 24 hours — longer in a cold workshop — before you think about writing on it.

Seasoning the Surface

This step is skipped more often than any other, and it is the reason so many new chalkboards never quite write properly. Chalkboard paint and bare slate both need seasoning so that chalk dust settles into the surface rather than smearing across it.

• Take the side of a stick of chalk and rub it over the whole board, covering it edge to edge.
• Wipe it away with a dry, soft cloth — an old tea towel works well.
• Repeat once more, then leave the board alone for a day before writing your first menu.

After seasoning, chalk lines come away cleanly with a dry eraser, and ghosting is far less likely. If you prefer a bolder, more permanent look for headings, liquid chalk pens are excellent — just note that they need a damp cloth to remove, so reserve them for the parts of the board you change least often.

Mounting It Securely

A slate board is heavy, so fix it properly. Mark your hole positions about 4cm in from each side and 3cm down from the top edge. Drill with a masonry bit at low speed and gentle pressure — too much force and you will blow out the back of the slate. A small piece of masking tape over the drill point helps stop the bit wandering on the smooth surface.

Fix rubber or plastic spacers between the slate and the wall so air can circulate behind it. This keeps the board clear of damp patches and makes it far easier to lift off for cleaning. Use wall plugs suited to your wall — masonry plugs for brick or block, proper hollow-wall fixings for plasterboard — and check with a spirit level before tightening anything down. Hang the board so the top edge sits around 150cm from the floor if you will be writing while standing at the worktop, or lower if children will use it too.

Everyday Care and Cleaning

Look after your board and it will serve you for years. Wipe it with a dry microfibre cloth or a proper felt eraser after each change of menu. For a deeper clean, use a barely damp cloth and let the surface dry fully before writing again.

• Avoid abrasive pads, cream cleaners and anything citrus-based, which strip the seasoned surface.
• Re-season the board every few months, or whenever chalk starts to smudge rather than erase.
• Never soak the slate or leave it wet against the wall.

Keep a small pot of chalk and an eraser on a nearby shelf, and the habit of planning the week's meals becomes something you actually keep up with. A handmade slate board is a practical piece of kitchen kit — but it is also the sort of thing guests notice and ask about, which is no bad thing at all.
