Refinishing the Garage Door

Painting Garage Doors Tactics

Primed or unprimed surfaces are what usually constitutes a hardboard garage door. The American Hardboard Association would help you out by recommending how to finish these doors best and apart from providing valuable tips to sort out old doors. Since they don’t have any grains or knots to shorten its life hardboard’s surface is ideal for use on garage doors for field coatings.


Hardboard used on garage doors is made of wood. It is necessary that its initial coating is well and evenly done to ensure that the garage door will stay coated and healthy longer. The coating is not just meant to enhance the look of the door, but also improve its durability. These recommendations work as guides to achieve both functions for a reasonable service life on the hardboard garage doors.

It’s Best To Follow Instructions

Giving the garage door a finish that is not as explained below could lead to the unsatisfactory performance. The primed doors, unlike the unprimed ones, do not require fast finishing after installation, preferably a gap of around half a month. Any paint that does not explicitly state its suitability for use in the exteriors, or is of a disreputable or unknown manufacturer, should be clearly avoided.

Use Quality Products

It should be of good quality, which can be assessed by the ingredient list on its label. A more desirable paint would be one which is accompanied by a performance warranty. Select the finishing systems meant for exterior use on the hardboard garage doors. For the primer, you have to use an oil or alkyd primer that will seal the face, back, and edges of the entire door and that is compatible with the top coat you use. Apart from this, only a primer specially formulated for the use on hardboard may be used.

Use Correct Primer

Before going on to paint the top coat layer, choose from either of the following paints: Acrylic latex, oil base or alkyd base. Once a stain goes on smooth hardboard, it stays while that on the textured hardboard must be dealt with. The results shown by the opaque acrylic latex stains are the most respected. The surface of the hardboard skin or panel must be clean, free of dust and dirt, mildew and other contamination. Gain a deeper understanding of roller doors and the broader subject of garage doors. Primer requirements, hardboard surface temperature, the rate of spread, and recommended application procedures are available on the label and should be followed. A thickness of four dry millimeters is advised for the film on all the surfaces of the wood.

The Finish

The prescribed finish label can be very helpful as working at the spread rate mentioned on the back will give the best results. Before fixing the door, apply the prescribed number of coats to the outside, inside and edges of the door. Unprimed doors need to be primed before everything else followed by two un-thinned finish coats and then a layer paint or stain. Use an alkyd oil primer to spot prime any areas of damage to the factory primer. Application of two finish coats should be applied once the primer coats dry.

Final Touches and Clean Up

Successful completion of the finish means that all that is left is cleaning and applying the final touches to the door. When the finish becomes badly eroded and thin, clean and prime the areas where the substrate is showing through, followed by complete pruning and finish coating, where the substrate is still covered, all you need to do is apply a finish coating.
