Note: Always test beforehand, if surface/material is compatible!

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 PRIMER's?

Montana PRIMER’s are all-round surface preparers that can be used on plastics, metal, styrofoam, leather, cardboard, wood and many other materials. We suggest trialing on a non visible area of your material to test for compatibility.

Which Montana PRIMER do I use when?

There are four different Montana PRIMER’s that can be used for different surfaces as listed below:


To be used on concrete, brick, terracotta, ceramic, leather, cardboard, wood and many other materials. White colored spray.

Montana METAL PRIMER T2400:

To be used on metal (iron or brass) or mineral surfaces. Dark-brown colored spray. Please note the Metal Primer unsuitable for priming aluminium. Please use our ALUMINIUM Primer instead!


To be used on some plastics and acrylic based surfaces. Clear colored spray. 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). Always trial on non-visible area of your material to check for compatibility!


To be used on most polystyrene and styrofoam surfaces. Cream colored spray. Always trial on non-visible area of your material to check for compatibility!

How do I start using my Montana 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 apply over Montana PRIMER’s?

You can apply any Montana-Cans color, tech or effect spray over Montana PRIMER’s once they are dried and cured. They will increase adhesion, help seal your substrates, create a more even surface and increase the longevity of the coatings applied over it.

Can I sand it to my desired surface finish?

Yes. You can sand Montana PRIMER’s once they are dry. Depening on the grade of the sand paper, smooth or rough surfaces can be achieved.

How long do Montana Montana PRIMER’s take to dry?

Drying times vary due to the PRIMER and the context it is being used. They usually require 15-20 minutes to be dust dry. Curing time can vary depending on substrate, ambient temperature, humidity levels and thickness of coats applied.

Can I use other coatings on Montana PRIMER’s other than sprays?

Yes. It is possible to use other coatings over Montana PRIMER’s spray once they are cured. We suggest always test on a non-visible area of the work for compatibility.
