Extreme Paints Garage & External Door Paint

Q: Can I use this garage door paint on automatic roller shutter doors?

Yes—once the surface is degreased and a suitable metal primer is applied, the gloss enamel withstands frequent rolling without flaking.

Q: Do I need to prime previously painted garage or external doors?

If the old door paint is sound, just clean and de-gloss it. Primer is only required for bare or rusty metal surfaces.

Q: How much gloss door paint do I need for a single garage door?

A 5 L tin of Extreme Paints Garage Door Paint covers around 12 m² in two coats—sufficient for most single up-and-over garage doors.

Q: Can I spray this gloss enamel paint indoors?

Yes—garage and external door paint can be sprayed indoors with proper ventilation and a respirator. Follow thinning guidelines.

Q: Is the gloss finish easy to clean on garage doors?

Yes—this solvent-based gloss paint creates a non-porous surface that easily wipes clean with mild detergent.

Q: Will the colour fade if the garage door is exposed to sunlight?

No—UV-stable pigments in this garage door gloss enamel ensure strong colour retention for over 5 years. Note: deep reds may dull slightly faster.

Q: Can I apply this garage door enamel in cold weather?

Apply this metal and wood door paint between 10 °C and 25 °C. Lower temperatures slow drying and may affect the finish.

Q: Does this paint resist oil or petrol stains on garage doors?

Extreme Paints Garage & External Door Paint is a single‑pack, heavy‑duty enamel formulated from premium long‑oil alkyd resins to deliver a resilient gloss coating on metal or timber doors. Rust‑inhibiting pigments guard steel against corrosion, while the flexible film expands and contracts with seasonal temperature swings to prevent cracking and peeling.

Ideal for up‑grading metal up‑and‑over garage shutters, side‑hinged timber doors, roller shutters and even commercial fire exits, the paint level‑flows to a high sheen that resists staining from road salt, oils and diesel fumes. Manufactured in the UK under ISO 9001 controls, it is available in convenient 5 L, 10 L and 20 L tins for domestic or trade projects.

Mild or galvanised steel (primed), aluminium (primed), hardwood, softwood, previously painted metal or timber that is sound and de‑glossed.
