Painting damaged porcelain
1 Start by applying tinted varnish to the exposed area, painting from the inside out. Pick up a lot of varnish on the brush, while being careful, so that it does not drip onto a non-damaged surface.
Do your best, that the brush does not touch the same place twice, as lumps may then form. When you get to the edge,,patches ", blot the excess paint off the brush, flattening his hair. Fast, with light movements (most paints begin to dry out after a minute or two) ,.fray "edges, dragging thin strands of paint over part of the old glaze. Change direction often, that there is no clear line.
2 While the paint is still wet, repeat the same "fraying" edge operation, this time applying a clear varnish. If you accidentally paint over part of an existing pattern, remove the paint with a stick soaked in solvent, moving it outside the drawing.
After drying, rub the first layer of varnish with the softest sandpaper. Finger pressure is to be minimal, First of all, try to smooth the edge of the vessel and any thickening. Wipe off any dust with a damp cloth. Apply another layer of colored varnish, correcting its shade if necessary. Try to keep the number of layers applied to a minimum.
3 If the color of the substrate is already satisfactory, and any excess paint is removed, paint the entire repair surface with clear varnish, and then "blur" its edges with a brush dipped in a solvent, so that they merge with the background of the whole. Do your best, so that the brush touches are as light as possible and the solvent does not attack the new paint.
The last layer of varnish should be protected against dust while drying. Cover the item to be repaired with a box or foil stretched over the frame, possibly keep it clean, a freshly washed cupboard.
