A 400 ml aerosol from the Winsor & Newton Professional range, printed GLOSS VARNISH and repeated in four more languages down to Firnis Glänzend. The can states 400 ml e and 280 g net, and the line under the name is the one that matters most: REMOVABLE. WITH UV PROTECTION.

Removable is not a small print detail, it is the entire argument for varnishing at all. A finished painting collects dust, cooking smoke and the grey film city air leaves on everything, and none of that comes off bare paint without taking paint with it. A removable varnish takes the dirt instead: years later the varnish is lifted, the grime leaves with it, and the paint underneath is untouched.

Gloss also does something to colour. Dark passages in oil and acrylic dry back dull and patchy because the binder sinks into the ground unevenly, so a black looks grey in one corner and rich in another. A gloss varnish refills that surface, evens the sheen across the canvas and pulls the darks back to the depth they had when they were wet.

The aerosol exists because a brush cannot varnish everything. Impasto, palette-knife texture and open canvas grain all drag at a loaded brush and pick colour back up; a spray never touches the surface. Hold the can upright about 25 to 30 cm away, sweep past the edge on both sides, and build two or three thin coats rather than one wet one.

The one thing this can cannot rush is drying. Acrylic is ready in days, but oil dries from the surface downward and stays soft underneath for months, so painters are usually told to wait around six months on an ordinary oil painting and longer on heavy impasto. If the picture still smells of oil, it is not ready.

We stock a second 400 ml gloss spray — the Daler-Rowney Artists' Clear Picture Varnish at Rs. 5,200 — so it is worth saying where the Rs. 615 goes. Both are gloss aerosols for oil and acrylic. What differs is what each label commits to: this can prints removable and with UV protection, and the Daler-Rowney can states neither on the face we have photographed. For a study, the cheaper can does the job; for work you expect to still own in twenty years, buy the label that promises it comes off again.

Spray outdoors or at an open window, keep the can away from heat and out of reach of children, and let an adult do the spraying.
