This is a version of the basic info sheet I provide for teaching sessions focusing on painting materials for model-making. It represents a small selection chosen for their availability, versatility and ease of use.
Prices shown are from 4/2014 and adjusted to include VAT. Full addresses can be found in the ‘Suppliers’ section.
Primers Priming is usually essential prior to painting any surface, especially cardboard (to minimise warping when using water-based paints) or Pvc (to provide a ‘keying’ surface for the paint). Also, if the surface is absorbent, like cardboard, priming ensures that it doesn’t draw too much from the paint too quickly so that it will harden properly in its own time. Best is Simoniz Acrylic Primer (a car spray primer), available white, grey or ‘red oxide’. Plastikote primer may be more common (B&Q etc.) but unfortunately it’s not as good. The surface it gives is slightly ‘plastic’ and will resist very thin washes whereas Simoniz keys better, even very slightly chalky when completely dry. Obtainable 4D, many garages Price c. £4-6 for a 500ml can
Bottle acrylic (DecoArt, Inscribe, Anita’s etc.) This type of acrylic paint, sold in plastic bottles, is much more ‘model friendly’ being thinner, generally more opaque and matt than standard tube acrylic. Obtainable many art or hobby shops; 4D (small selection); Tiranti (Anita’s); Hobbycraft (DecoArt); artdiscount.co.uk (DecoArt) Price varies £0.99 -£1.99 for a 59ml bottle
Gouache Regular gouache contains minimal binder so it will not normally stay well on non-absorbent surfaces such as Pvc or Sculpey, but can be modified by mixing in equal quantity of Pva wood glue (e.g. Evo Stik Wood). Covers well. Obtainable most art suppliers Price varies
Reeve’s Tempera The cheapest colour paint around. Weak adhesion and pigment strength, but perfect for basecoating large areas. Available in 500ml bottles or cakes (used like watercolour). Pva can be added to strengthen adhesion. Obtainable most art shops Price e.g. Reeves Redimix £1.52 per 500ml (Atlantis)
Rosco scenic paints i.e. ‘Super Saturated’ range. Super-concentrated and properly matt acrylic paint which will still provide full coverage even when heavily diluted and with good adhesion on many surfaces. Expensive though because it’s only usually available in minimum 1litre pots. 4D did trial offering smaller amounts (230ml tins) and there are some left, but too little response for them to continue. Obtainable 4D, Flints, Brodie&Middleton Price 1ltr £13-28, 250ml £4-8 (4D)
Acrylic retarder A colourless gel medium which slows down drying of acrylic paint making it much longer ‘workable’ and also transparent (if required) for ‘scumbling’ and glazing. Basically giving it some of the workability of oil paint but not the endless drying time Obtainable art shops. Price Winsor&Newton brand recommended c.£8 per 237ml tub. Also now available as a fluid.
Cold enamels Familiar as small (14ml) tins from Humbrol. A thin-coating but opaque, quick-drying oil-based paint designed for plastic or metal (will even stick to latex) and one of the most durable paints around! Available in gloss, satin or matt. Matt versions dry very matt, more so than most acrylics. Can be thinned with white spirit to make washes or stains. Will keep indefinitely if tin is properly closed. Must be thoroughly stirred before each use because paint mix separates. Obtainable model/hobby shops e.g. Hobbycraft; some art shops; best online retailer wonderlandmodels.com Price £1.30-1.80 per tin
Cracking medium A special glycerine-type medium which, when applied between two layers of paint, will cause decorative craquelure effects. Obtainable craft/hobby shops Price c.£2-3 (60ml) or Polyvine ‘Crackle glaze’ 500ml £9.75 (Flints) or Leyland SDM
Wood stains, inks Properly formulated wood stains are most appropriate for changing the colour of model wood because they are designed to soak in and enhance (rather than mask) the natural grain. Can be expensive though, at up to £8 for a 250ml tin. Drawing inks, pure watercolour, liquid shoe polish, or pigment dissolved in white spirit are all reasonably good alternatives. Wilkinsons have fairly cheap wood stains but get the spirit-based because these infiltrate the wood fibres better. Leyland SDM offers the best range of wood stains, including 60ml bottles.
Spraypaints I’ve found the Montana range of spraypaints the most reliable, versatile, and the most economical. They’re also the ones most often stocked in general art/graphics shops. I use spraypaints mainly as a very quick method of basecoating i.e. spraying usually a dark basecoat on a brickwork-textured Kapa-line foam surface as an undercoat for dry-brushing. Spray infiltrates into recesses more quickly than brush painting if sprayed properly. Can be worked on with acrylics, enamels, pastels etc. after an hour if need be. ‘Montana Gold’ has the best choice of colours, but Montana’s ‘MTN’ range have the advantage of being ‘low pressure’ making it easier to spray small-scale work. Obtainable 4D; Chrome&Black; London Graphic Centre; UAL college shops, and many other art/graphics suppliers.
Chrome&Black http://www.chromeandblack.com is the best and cheapest source for graffiti sprays in London. ‘Montana Gold’ 400ml cans £3.90 (inc.VAT) ‘MTN 94’ 400ml cans £3.70. They have a full range of accessories for spray work i.e. a variety of spare caps for different spray-widths or effects. Pack of 10 caps £1.99.
They also stock a number of protective masks which are obviously chosen for their ‘look’ and .. black nitrile disposable gloves! .. presumably either because they look ‘cooler’ than off-white latex or because they don’t show up in the dark!
