The card that goes on the face of the letters comes 800
microns thick and is usually glued onto the polystyrene
using a solvent based contact adhesive. The card is
usually vinyl faced with a Hexis 5000 series Branded
Vinyl in either gloss or matt.
The sides of the letters are painted with an acrylic resin coating which is basically a vinyl matt emulsion, we generally use the Crown brand of paints. We put two layers of paint onto the letters for a better finish to the product.
Natural white finish polystyrene letters are cut and then cleaned and are used as they come.
Card Faced polystyrene letters are cut and then a coloured vinyl card is applied to the face of the letters to give a smooth finish. Available in gloss or matt. The letters can also be supplied with painted sides in a matt finish using vinyl matt emulsion.
Painted Polystyrene letters are first cut and then given two layers of high quality vinyl matt emulsion paint. We use the Crown Brand of paints because of their quality and service and their ability to match colours to BS and RAL ranges and also to Pantone colour swatches.
Polystyrene Letters for Outside Use.
Polystyrene letters for outside use can be made to order for short term use or permanent exterior use if required for a shop sign.
If the letters are required for short term use a couple layers of water based resin and two layers of masonary paint will do the job well.
When the letters are required for permanent use outside, we use a higher density styrofoam painted to a matt or gloss finish.
The letters can be faced in MDF, acrylic, aluminium composite, foamPVC or resin faced.
The exterior grade styrofoam letters when treated with a resin coating can be textured in a liquefied stone finish. The letters can be glitter coated or sand coated and painted to give a textured masonry finish or to make them look like concrete letters. For 12" high letters we use simplefix stand off fixings and for larger letters we use brass nut and bolt stand off fixings. The letters can also be glued onto the fascia with epoxy resin. Depending on the font used the letters are often reinforced with fibreglass on the back for strength.
