How to paint a metal garage door - Using Hammerite

Useful tip: We advise painting your metal garage door on a dry day with temperatures above 10 degrees. This ensures the paint will dry correctly and your endeavour won't be wasted. If you’re painting a brand new garage door, it may already have a powder or primer coat so you can skip ahead to step five.

Step 1. Remove old paint Lay down a dust sheet and put on a mask and goggles to protect yourself from dust. To help you get the best finish on your door, you need to get rid of blistering, flaking or bubbling paint. Use a flat scraper to remove the old paint so the surface is smooth. For the rest of the door, use a piece of 180 grit sandpaper and quickly rub down the surface. Open the door and do the same to the edges.

Step 2. Clean the door Use a sugar soap solution and sponge to clean the door and remove accumulated grease and dirt. Clean the edges and hinges so you have a smooth surface ready for painting. Let the door dry.

Step 3. Protect fixtures Use masking or decorator’s tape to protect handles and any other section of the door you don’t want to get paint on.

Step 4. Apply the first coat of paint Paint the door, once you’ve covered the entire door, take a look to see if it needs a second coat. When you’re happy with the colour and coverage, remove the tape from the handle and fixtures while the paint is still wet. All that’s left to do then is let the paint completely dry.
