Features of painting garage doors

The gate has paint applied to it as structural protection.

Details of the piece:

Garage doors are a large surface area with hard-to-reach areas. You can paint them with a brush, but not very effectively. It is better to use such a tool to process the most difficult areas, such as:

joints of the canvas;
stiffeners.

These areas can’t always be painted using a roller. Using a sprayer has a major drawback: tiny paint droplets create "fog" in the work area that settles on nearby objects, usually neighboring garages painted a different color.

Advice: Take precautions to shield nearby objects from paint when selecting a sprayer for painting gates.

Metal is usually used to make gates, which is subject to corrosion over time. This requires cleaning the structure from rust and the remains of existing paint layers before painting. otherwise, the new layer will not look very nice and is unlikely to last for a long time.

Advice: You need to make sure that the structure is free of rust on the outside as well as the inside. It is important to thoroughly inspect the surfaces and, if required, clean all the way down to the metal. Subsequently, the gate is cleaned using a solvent like 646.

To increase the durability of the paint application, the gate surfaces must be carefully primed (see. What is the primer for: technological nuances of finishing work). The primer is selected depending on the type of paint used, the amount that can be spent. How to use a specific primer is indicated in the instructions located on the packaging. It is better if the primer and paint are from the same manufacturer.

What are the requirements for gate paint

Finding out what qualities the gate should have will help you paint it correctly and ensure that the coating offers excellent protection and a lovely appearance.

Among these qualities are:

Adhesion level. The metal surface has a unique structure, and the chosen paint must meet the requirements for it and be intended specifically for coating metal.
Lack of various chemical additives, coming into contact with the metal coating, which causes its oxidation and, as a result, will lead to the formation of blisters on the painted surface.
The instructions for the coating should contain a recommendation that this coating has waterproof properties and tolerates the effects of moisture well – the most destructive composition for metal parts.

Advice: Metal expands at high temperatures, which can result in paint layer cracks. Keep this in mind when selecting paint. You must buy paint that forms an elastic layer that can tolerate the expansion and contraction of the metal surface in order to prevent this.

Paint for garage doors must withstand the effects of chemical elements and fuels and lubricants, resist small mechanical loads, while maintaining the layer intact.

What kind of paint is used for garage doors

Fundamental specifications for paint:

Heat resistance.
Water resistance.
Intended for painting metal, for outdoor use.
The paint layer must withstand chemicals.
Have an elastic structure.
Resist mechanical loads.

Such a coating costs more than comparable materials for interior work. These are the physical characteristics of three types of modern paints.

Acrylic. The most modern type of coating that meets the properties listed above. Its cost is high, but these costs are justified by the long service life of the material if the application procedure is followed.
Organic silicon. It is characterized by high strength and increased elasticity after applying a protective layer. It has excellent adhesion to many materials, and the silicon content in the composition gives the metal additional properties against corrosion. The compositions are practically odorless, do not emit harmful substances when used, which allows them to be used for interior surfaces.
Alkyd. Used for external and internal painting of metal, has high elasticity and resistance to mechanical damage. It has a huge selection of different color options, but many brands of such paint do not tolerate ultraviolet rays well, which leads to a deterioration in the color indicators of the coating.

Advice: Select organosilicon compounds that can tolerate high temperatures without losing their physical qualities when positioning the gate in direct sunlight.

The following coatings’ characteristics should be considered when selecting paint for hand-painted garage doors. Garage doors can benefit from long-term protection from premium external enamel.

How to choose a color for garage doors

Which hue should the gates be painted? Although quality is more important, there are some guidelines that must be followed in this situation.

The red garage gates will stand out if there are multiple garages with green gates in a row, and this may lead to officials considering "disfiguring the face of the city." It is perfectly acceptable to paint them the same color when building a metal garage, and it is preferable to choose a color that complements the brick, as seen in the example.

If you use the proper techniques and equipment, removing old paint from a gate can be a simple task. Work carefully to prevent scratching the gate’s surface, whether you decide to use a heat gun, chemical remover, or the more conventional sanding method to remove the paint. In order to help you get your gate ready for a new coat of paint, this article will walk you through each step and provide advice on how to make it go as smoothly and hassle-free as possible.

How to prepare a gate for painting

Rusted or previously painted gates need to be prepped before painting.

The surface is cleaned. If there is a layer of previous paint on the gate, it must be removed using a wire brush, grinder or hair dryer.
Surface treatment can be carried out with a special remover, but you need to act carefully so as not to get poisoned by toxic fumes. This stage of the work is very important, otherwise the paint will peel off under the influence of precipitation and sudden temperature changes and the work will need to be done again.
To obtain maximum adhesion to a metal surface, it should be sanded with fine-grained sandpaper.
Surfaces are degreased. After removing the old paint, the metal must be degreased with a solvent. When processing, it is necessary to capture the entire surface at once, including hard-to-reach places. The final result of the work depends on the quality of this operation.
Primer is applied. At this stage, the gate is covered with three thin layers of primer used for metal surfaces. Each layer is applied after the previous one has dried. This improves the adhesion of the gate surface to the paint. In this case, the enamel layer will become smooth and even, and will acquire a finished look.
The gate is cleaned of dust and dirt using a garden hose, a rough sponge and any detergent.

Advice: The best weather for doing any work is bright and sunny. Painting the gate needs to wait until a different day in overcast weather with a chance of rain.

Methods for removing paint from metal

Paint removal from metal can be accomplished in a few ways:

Burning. This is the most radical method, in which the coating is burned with a blowtorch. It cannot be used for sheet metal, which may warp, cast iron, which will develop cracks, or galvanized sheets. The advantages of the process are speed, the disadvantage is fire hazard. After processing, scale will appear on the surface, which will need to be sanded. Removing paint from metal in this way can bring more trouble than good, which does not allow it to be used often.
Mechanical method. In this case, ordinary sandpaper or a metal brush is used. It is convenient to use a special attachment on a drill. First, an abrasive with large granules goes over the metal, after which the surface is sanded with a finer abrasive. Advantages of the method – availability and convenience when processing a small area.
Chemical method. In this case, various chemicals are used – washes and solvents. Washes can be of different consistencies:

liquid;
gel, which is applied with a brush and can be evenly distributed over the surface;
aerosol;
water-soluble powders.

Apply the solution to the coating and let it sit for up to 30 minutes to remove old paint from metal. Using a spatula, remove the old enamel as it starts to peel off and swell.

An anti-corrosion primer is applied to the surface right away after the paint is removed.

Method	Description
Sanding	Use a sander or sandpaper to remove the paint by rubbing it off the gate surface.
Heat Gun	Apply heat to soften the paint, making it easier to scrape off with a putty knife.
Chemical Stripper	Apply a paint stripper, wait for it to work, and then scrape off the softened paint.
Pressure Washing	Use a pressure washer to blast the paint off, especially if it"s already loose or peeling.

Even though removing old paint from a gate can seem like a difficult task, it can be completed quickly and effectively with the correct method. Every technique, including chemical paint removers, heat guns, and good ol’ elbow grease and a scraper, has advantages and disadvantages. Selecting the one that best suits your needs and the kind of paint you’re working with is crucial.

It’s critical to prioritize safety first. Wear safety gear whenever possible, such as goggles, a mask, and gloves, especially when working with chemical strippers or sanding the surface. It is very important to have ventilation, particularly when working indoors or in small spaces.

Take your time and thoroughly prepare the gate’s surface before painting it with a fresh coat of paint once the old paint has been successfully removed. A smooth, durable finish can be ensured by sanding any rough spots that may still be there and by clearing away dust and debris. Your gate’s final appearance is greatly influenced by a surface that has been properly prepared.
