COLOURLOCK Plastic Primer ND — adhesion primer for plastic surfaces

What is COLOURLOCK Plastic Primer ND for? — The primer improves how well paints, coatings and repair materials grip plastic, steadies the surface and gives you even, long-lasting results on smart-repair and refurbishing jobs.

COLOURLOCK Plastic Primer ND is the pro-grade primer for any plastic surface that needs reliable grip before you paint or repair it. On interior parts like plastic trim, handle recesses, consoles or boot components, plastic often holds on poorly: plasticisers, slickness, micro-texture or silicone residue stop coatings from keying in cleanly. Plastic Primer ND lays down a safe, uniform base for adhesion and makes repairs visibly more solid and more even to look at — ideal for cars, furniture, motorhomes and plenty of plastic components.

• Strong grip boost – The primer anchors on all sorts of plastics and gives paint and repair products something proper to bond to.
• Even surface stabilising – Cuts down on adhesion problems on smooth, slightly oily or lightly textured plastic surfaces.
• Pro base for refurbishing – A must before COLOURLOCK plastic paints or texture repairs.

Adhesion technology & how it works on plastic

Plastic Primer ND carries purpose-built bonding agents that latch onto polymer surfaces and raise their surface tension. Plastics like ABS, PVC or PP often have very smooth or slightly greasy surfaces that only take paint poorly. Once you apply it, the primer forms a micro-fine, transparent adhesion matrix that later coatings can anchor into perfectly. The formula is built so it doesn't lay down a thick layer — it keeps the plastic's natural texture. That way paint systems cover more evenly and show fewer peeling or edge problems.

Prep, application & the perfect base for paint

Before you apply Plastic Primer ND, clean and degrease the surface thoroughly, ideally with suitable cleaners or GLD/ Degreaser (link placeholder). Lay the primer down thin and even — a fine film is enough. After a short flash-off, the part is ready for paint or a texture repair. Keep the layers from getting too thick, since that tends to make adhesion worse. On high-wear spots like door handles, sill strips or centre-console surfaces the primer keeps later coatings longer-lasting and more abrasion-resistant.

Results, uses & how it differs from Leather Primer

After you use Plastic Primer ND, you get a much grippier plastic surface where paint holds evenly and stays put. The payoff is cleaner repairs, less flaking and a visually harmonious panel. The primer suits all vehicle interior parts, boot trim, plastic housings, furniture surfaces and other components made from common plastics. It doesn't replace cleaning or a repair compound — it forms the base you need for COLOURLOCK plastic paints, texture fillers or flexible coatings. Unlike Leather Primer, Plastic Primer ND is tuned specifically for plastic and does nothing on leather surfaces.

Common questions about COLOURLOCK Plastic Primer ND

Which plastics does the primer work on?

Most plastics common in vehicles and furniture, like ABS, PVC, PP and textured interior parts.

Is the primer visible after application?

No. It dries transparent and forms only an ultra-fine adhesion film.

Do I have to degrease before the primer?

Yes. Residue like silicones or grease can hurt adhesion badly.

Can I use the primer on leather too?

No. It's built for plastic only. For leather, go with Leather Primer.

How long does the grip boost last?

Permanently. The adhesion film stays stable and gives every following coating a reliable base.
