Montana Plastic Primer is the perfect pre-treatment for plastic surfaces. After priming and drying, plastic surfaces can be painted with Montana sprays that have a synthetic, acrylic, or nitro-combination base.

The PLASTIC Primer can be used with the following types of plastic:

  • Polypropylene Rubber, Modified (EPDM)

  • Acrylic Butadiene Styrene Plastics (ABS)

  • Glass-Fibre Reinforced Plastics (GfK)

  • Hard Polyvinyl Chloride (Hard-Pvc)

  • Polyurethane (PUR)

  • Polystyrene (PS)

  • Polyamide (PA)

The PLASTIC PRIMER can NOT be used on the following types of plastic:

  • High-density polyethylene (HDPE)


- Improves the adhesion between primer and top coat.

- Good resistance to external influences

- High filling power


Shake can vigorously for 2-3 minutes before use. Apply PLASTIC PRIMER in maximum 2-3 thin layers, spraying in sweeping motions. Allow each coating to dry for at least 5 minutes. Can be overpainted after 3 hours. Further coats of alternative products might require a drying time of 24 hours or more depending on application style. Always test spray on a non-visible area to check the compatibility of lacquer or paint. For optimal lifespan, store cans with the nozzle on.


- Surfaces should be dry and clean of oil, dirt or silicones

- Sand back with a fine-grid sandpaper (280-400 grain) and carefully remove all residue afterwards

- Shake the can well for at least 3 minutes

- Spray distance should be at least 25cm/10in

- Test spray on a non-visible area

- Apply in maximum 2-3 thin layers in a grid pattern. Leave every layer to dry at least 5 min.

When should I use a primer?

The goal of priming is to create a neutral surface of which to apply other coatings onto that will have the longest possible lifespan and the most aesthetic finish as desired. Montana Primers are for the pre-treatment and preperation of surfaces and will offer the greatest adhesion and protection to apply further coatings onto.

When do I use Montana PLASTIC PRIMER?

The Montana PLASTIC PRIMER is ideal for preparing plastic materials for the application of color coats to assist in adhesion and reducing the risk of tearing and cracking. Montana PLASTIC PRIMER is a surface preparer that can be used on the following hard plastics: polyurethane (PUR), polystyrene (PS), polyamide (PA), polypropylene rubber, modified (EPDM), acrylic butadiene styrene plastics (ABS), glass-fibre reinforced plastics (GfK), hard polyvinyl chloride (Hard-PVC).

Will my Montana PLASTIC PRIMER work with all plastics?

Although suitable for many plastics, due to the varied chemical make up’s of some plastic and acrylic surfaces, some materials will not allow any paints or coatings to adhere. We suggest trialing on a non-visible area of your material to test for compatibility.

What do I need to watch out for when working with plastic based materials?

When using plastic materials, always be aware of expansion and contraction. This occurs through exposure to heat and cold. If your substrate expands in heat or contracts in cold beyond that of the flexibility of your coatings, then cracking, peeling or tearing will occur regardless of pre-treatment. Some plastic based materials are manufactured for particular functions. Their chemical make up may not allow any coatings to be applied. Keep your coated objects away from extreme heat/cold and direct sunlight to extend the lifespan of your project.

What do I need to look out for when using my PLASTIC PRIMER?

PLASTIC PRIMER can seal the surface of most foams for the application of further coatings. It is important that you ensure that the complete surface of your foam is sealed leaving no pin holes or air openings. This avoids any solvents reaching the raw foam and agitating it. You can ensure complete sealing by applying multiple thin layers.

Why did my foam melt when I applied my PLASTIC PRIMER?

Due to the endless chemical possibilities that manufacturers of foams can use, PLASTIC PRIMER could penetrate low quality or poorly constructed foams if not compatible, applied too close, too quickly or not allowed to dry. We suggest trialing on a non-visible area of your material to test for compatibility.

How do I start using my Montana PLASTIC PRIMER?

Remove the spray nozzle and turn the can upside down. Strike with your palm allowing safety ring to fall out. Shake vigerously for 2-3 minutes ensuring you can hear the mixing balls moving freely. Replace the cap back onto the top of the can valve and trigger away from substrate to test. If flowing freely you can start painting.

Which coatings can be applied over the PLASTIC PRIMER?

You can apply any Montana-Cans color, tech or effect spray over the PLASTIC PRIMER once it has dried. It will increase adhession, help seal your substrate, create a more even surface and increase the longevity of the coatings applied over it.

How long does Montana Montana PLASTIC PRIMER spray take to dry?

Drying time is usually 15-20 minutes to be dust dry but can vary depending on substrate, ambient temperature, humidity levels and thickness of coats applied. Painted objects should be left to dry for 24-48 hours to cure.

Can I use other coatings on it other then sprays?

Yes. It is possible to use other coatings over PLASTIC PRIMER spray once it is dry. We suggest always test on a non-visible area of the work for compatibility.
