The Benefits

One of the most difficult substrates to paint, glass needs to be primed properly or else paints simply won’t stick to the surface. Using Zinsser products, in particular Zinsser Bulls Eye 1-2-3, ensures proper application when painting glass.

Properly primed glass surfaces mean topcoats can be applied quickly, saving money in labour and minimising disruption for businesses that paint their windows for advertising or privacy, freeing up staff to get back to serving customers. Zinsser Bulls Eye 1-2-3 is an easy to use glass primer that dries quickly and means businesses can easily update their painted windows with new colour schemes and branding.

Zinsser listens to contactors and develops new products – or adds features to existing products – to meet their changing needs, delivering world class products that meet “real world” challenges, providing tried and tested solutions to painting problems, such as painting glass.

Step 1. Surface Preparation

Clear the surface free of contaminants and anything else that could affect the adhesion or application of materials and Zinsser products, and then degrease overall with methylated spirits, changing the cloth regularly.

All visible signs of organic growths should be removed and the affected areas treated with Zinsser Mould Killer & Remover, in accordance with the manufacturer’s instructions, and allowed the dry before priming.

Step 2. Priming

Prime the surface overall with one full coat of Zinsser Bulls Eye 1-2-3 in accordance with the manufacturer’s instructions and allow a minimum of 1 hour’s drying time in normal drying conditions before decorating.

Step 3. Decoration

Now the glass surface has been suitably prepared and properly primed, decorate with two full coats of Zinsser Perma-White Interior in accordance with the manufacturer’s instructions and allow a minimum drying time of two hours between coats. The coating is available in matt, satin and semi-gloss finishes in over 4,000+ RAL, NCS and BS colours. For exterior projects, decorate the surface with two full coats of Zinsser Allcoat Exterior Satin or Gloss in accordance with the manufacturer’s instructions. Allow a minimum drying time of one hour between coats.
