How to mount a ceramic photo on the stone

Mounting a ceramic plaque doesn't require special tools and, in most cases, takes less than half an hour. What matters is not rushing the steps and working in dry weather. Below is the natural order of things.

What you'll need

• Neutral silicone-based adhesive or a two-component adhesive for stone. Regular acetic silicone, the kind used in bathrooms, is not suitable: over time it can stain marble.
• A clean cloth and technical alcohol or acetone, to degrease the surface.
• Paper adhesive tape, to hold the plaque temporarily while the adhesive sets.
• A small level or a ruler, if you want to make sure the plaque sits straight.

Step 1 — preparing the surface

Clean the area where the photo will sit thoroughly. Remove dust, moss, and candle wax marks. If the stone has been washed, let it dry completely — adhesive doesn't bond on moisture. Finally, wipe the area with technical alcohol and let it evaporate for a minute.

Step 2 — the trial without adhesive

Place the plaque on the stone and look at it from two or three steps away, from the front and slightly from the side. Check that it sits straight relative to the inscription and that the distances to the edges satisfy you. Discreetly mark the corners with paper tape, so you know exactly where to place it. This step seems minor, but it's what separates a tidy mounting from a crooked one.

Step 3 — applying the adhesive

Put the adhesive on the back of the plaque, not on the stone: a few dots toward the corners and one in the middle. Don't cover the whole surface and don't overdo the amount — the excess squeezes out at the edges and is hard to clean off marble. If it does squeeze out, wipe it away right away, while it's still fresh.

Step 4 — positioning and fixing

Place the plaque on the marks you made and press gently and evenly for a few seconds. Don't slide it on the stone once it has touched the adhesive. Fix it with two pieces of paper tape in a cross shape, so it doesn't slip until it sets. Remove the tape the next day.

Step 5 — drying

The adhesive needs 24 hours to fully set. During this time, avoid direct rain if possible. Don't wash the monument and don't touch the plaque. After a day, the mounting is permanent.

Mistakes that cost you

• Mounting on wet stone or in temperatures below freezing — the adhesive won't bond correctly.
• Regular acetic silicone, which over the years can leave a yellowish stain on marble.
• Too much adhesive, which squeezes out at the edges and hardens before you can wipe it off.
• Repositioning after the plaque has touched the adhesive — this creates a film that holds poorly.
• Mounting without a prior trial run, which most often results in slightly tilted plaques.

If the monument has a recessed hollow, the plaque just needs to be set into it with a little adhesive at the base. Never force a plaque into a hollow that's too small — the ceramic will crack.

When it's worth calling a stonemason

If the photo is large, if the monument is tall and you'd need a ladder, or if the recess needs to be carved into the stone, it's better to ask a stonemason for help. For someone experienced it's a quarter-hour job, and the risk of breaking the plaque disappears.
