How to spray paint with water-based paints? What is the best type of paint to use for spray painting? Water-based paints are a great choice. As they provide many advantages over oil-based paints. Whether you want to lightly touch up your car or completely refinish it. Water-based paints will give you the smooth finish that you desire with no heavy fumes and easy clean-up. In this article, we’ll take a look at how to choose the right paint for your project. Then show you how to spray paint using water-based finishes!
How do I spray paint with water-based paints?
How should I spray it?
Spray painting with water-based paint can be done in a number of ways, although the easiest to use will be an HVLP (high volume low pressure) spray gun. A standard air compressor and inexpensive gravity feed guns are also good options for applying water-based finishes like General Finishes Milk Paint or GF High-Performance Topcoat.
- Brush or spray application
- Interior and exterior rated
- 100% acrylic based paints
What is the best surface preparation?
Make sure that your surfaces are clean and free from dirt before you begin spraying your finish, as this could cause unsightly marks on your work when it dries. Most types of wood furniture should not need any additional sanding if they have already been cleaned thoroughly; however, hardwood floors may require some extra prep depending on their condition prior to painting.
How do I choose a gun for water-based paints?
What are the main types of spray guns?
There are four main types of spray paint to choose from: compressed air, gravity feed (or siphon), HVLP (high volume low pressure), and C.A.S. which stands for Continuous Air System; however, only the first three kinds will be suitable for water-based paints like GF Finishes under normal conditions in a home workshop setting since they require an external compressor or tank to force the paint through them at high pressure in order to atomize properly – not something we recommend trying yourself!
The most popular type of gun among hobbyists is probably the inexpensive HVLP one you can find on Amazon for around $30 – $40, the NEIKO 31215A HVLP Gravity Feed Air Spray Paint Gun | 1.7 mm Nozzle Size | 600 cc | Air Gauge Regulator is priced at $49.99. These are very easy to use, although they tend to be more expensive than other types of guns that require an external compressor or tank depending on your project needs.
What gun should I choose for my project?
The main advantages of the spray guns for water-based paints are that they are easy to use and provide even coverage with no runs or sags. The type of spray paint you’ll need will depend on the size of your project, as well as its complexity. If you’re just painting a small piece like a chair leg, then any basic HVLP gun from Amazon would be perfectly fine! For larger projects such as refinishing an entire car, it may be more economical to rent professional-grade equipment or go through a local automotive dealer who can supply all necessary items for around $50 – $100 per day depending on which types of materials you’d like to purchase there.
For smaller jobs requiring water-based paints, using a spray gun is simple and it provides even coverage with no sags or runs.
How do I thin water-based paint for spray guns?
Water-based paints can be thinned with water or paint thinner, depending on the consistency you would like to achieve. If your finish has dried out and seems too thick for spraying purposes, simply add a few drops of water at a time until it flows smoothly through your gun – do not use more than 20% added liquid! Thinning is usually unnecessary when using HVLP guns because they atomize very finely already; however, there are some exceptions where this technique may make sense if you’re trying to spray coatings that contain large amounts of solids such as metallic flakes.
Why do you need to thin water-based paint?
The main reason to thin water-based paint is to make it easier and more efficient to apply. This can be achieved by adding a few drops of thinner or plain old water at a time until the desired consistency for your project has been reached – do not add too much liquid, though! Any HVLP spray gun will generally atomize paints very finely already; however, there are some projects where this technique may make sense if you’re trying to spray coatings that contain larger amounts of solids such as metallic flakes.
Can you thin acrylic paint with water?
Yes, acrylic paint can be thinned with water if necessary – however, the resulting finish may not have as much gloss or durability after it dries.
How do I thin latex paint for spray guns?
Latex paint can be thinned with water or, if you want to achieve a more matte finish, then adding white spirit is recommended. When using latex paints in spray gun applications outdoors it’s best to use an HVLP unit because the pressure required for thicker coatings may not be achievable through other types of equipment. Latex paints are generally considered better suited for smaller projects requiring multiple coats due to their slower drying time compared to oil-based enamels; however, there are some exceptions where this technique may make sense if you’re trying to spray coatings that contain large amounts of solids such as metallic flakes.
What happens when I add too much thinner?
If your project requires just a layer and has no intricate details or design, then adding too much thinner to your paint will not be an issue. However, if you’re trying to achieve extremely fine detail with multiple coats of thinned latex paint it’s best to avoid this practice because the smooth finish may result in a less detailed appearance than desired.
What should I use for my water-based project?
Any type of spray gun can be used for water-based projects; however, HVLP guns are often preferred due to their versatility and ability to deliver superior results even on very large surfaces. The Graco Truecoat Series is highly recommended by General Finishes since they offer high flow rates that won’t bog down under pressure or weight when using thicker paints such as enamels which require more air pressure to produce a smooth, even finish.
- CONTROL SPEED: Variable speed control lets you determine the pace for ultimate control on your project; Reversible spray tip allows you to reverse the tip when clogged to keep you spraying
- STORAGE CASE: Durable storage case protects sprayer while keeping tips and accessories organized
- SPRAY PAINT UNTHINNED: Stainless Steel Piston Pump allows you to spray paint unthinned at high pressure
- SPRAY IN ANY DIRECTION: VacuValve technology creates an air tight system allowing you to spray in any direction, even upside down
- RECOMMENDED USE: Annual use recommendation is up to 25 gallons per year
What is the best way to apply water-based paint?
The Graco TrueCoat Series HVLP spray gun offers superior results on large surfaces and projects. It requires thick paints such as enamels due to its ability to provide high flow rates without bogging down under pressure or weight. It’s highly recommended by General Finishes for furniture restoration. Because it provides professional results with minimal overspray compared to other types of equipment.
Trouble Shooting Guide to spray paint with water-based paints
Why is the spray paint not spraying properly?
If you’re having trouble with your gun, it may be clogged or too dirty to function – remove and clean the nozzle completely. If this doesn’t help, check for a blockage in your hose; you can use an old toothbrush to loosen any dried material inside which will allow airflow again. Also make sure that the pressure regulator on your compressor isn’t set too high (if using one), as well as checking that there aren’t any leaks along the length of hose between where it connects to both ends!
What should I do if my paint keeps clogging up?
First, ensure that no foreign particles are obstructing either end of the nozzle. Wipe down any residue with a lint-free cloth. If the problem persists, clean your gun completely. Remove and disassemble it according to the manufacturer’s instructions. Then use an old toothbrush to loosen any dried paint in hard-to-reach areas (making sure not to damage anything). Also, make sure that there aren’t any leaks along the length of the hose between where it connects both ends!
Spray paint with water-based paints better than brush painting?
Spray painting is generally more economical for large projects like fence painting or outdoor walls. However, you may need multiple coats. More than what would be required if brushed on instead due to its quick dry time. If applying by hand or with a power paint roller, then you’ll also want to wait at least 24 hours before applying a second coat for maximum durability.
How do you clean the spray gun after using water-based paint?
To clean your equipment, simply remove and rinse it under warm tap water. Do it until all residue from either paint or thinner go away (if thinning liquid in this way). Then, dry off any excess moisture before placing back into storage – make sure to use compressed air if possible! If there’s still some dried material stuck inside which won’t loosen easily with gentle tapping motions; we recommend soaking overnight instead. But never soak acrylic paints since these contain large amounts of solids such as metallic flakes that will not dissolve in a solvent as epoxy products can.
What type of extra equipment might I need?
Depending on what types of materials you’ll be using with your finishing system (and how many). Additional items such as drop cloths, masks, and gloves could come in very useful. Keep in mind that you’ll also need to purchase cleaning supplies such as mineral spirits (for thinner) or acetone for acrylic paints if using these instead of water-based products.
What is the best type of paintbrush to use when spraying with Water-based Paints?
When applying an HVLP spray system, it’s generally better to opt for either a gravity feed or dual-action airbrush than standard brush painting techniques which can result in significant overspray. This will save time and give much more accurate results! If you’re looking for brushes designed specifically for airbrushing purposes, then check out our range here.
Is there any prepping needed before spraying water-based finish on top of previously painted surfaces?
Yes. Prepare the surface as you would for standard brush painting techniques, making sure to sand it down with 400-grit sandpaper first before cleaning off any dust particles by wiping it over with either mineral spirits or tack cloths that are lint-free.
What type of finish can I expect if I spray paint with water-based paints?
The resulting appearance will be similar to that achieved when brushing on a product. Just remember that this may not have quite as much gloss or durability since each coat dries so quickly compared to conventional products!
How do I achieve more opaque coverage and reduce the orange peel effect?
To minimize orange peel (or general unevenness), we recommend applying at least two coats. Wait until have dried completely. Then lightly sand the surface with 400-grit sandpaper between each coat. Do it until you’ve achieved a smooth and even appearance.
- 400 Grit
- For sanding between coats of varnish, lacquer, paint and other finishes.
- Silicon carbide abrasive, a sharp synthetic mineral that cuts fast and smooth
- Waterproof paper
How do I prevent the paint from dripping?
To avoid over-spray even when you spray paint with water-based paints, start by holding your gun around 15cm away. Then gradually moving closer as required (never directly at) while constantly checking via a small mirror. Make sure to maintain an upright angle of 45º for optimal results! If it’s still too thick then start thinning down using either water or solvent. This depends on what type of products you’re using. Just remember that acrylic paints require this instead. Also, ensure that there are no obstructions inside the spray nozzle. For example, dried material blocking off either end which can cause problems.
