No two unpainted surfaces are the same – different surfaces need different preparation to allow for the best result. Plus, the appropriate precoat and topcoat will also differ depending on the surface.
These processes are suitable for unpainted (bare) surfaces. Acrylic paint was first developed in the 1950s as house paint and made commercially available as artist grade paint in the 1960s.
Since then, it’s become a primary art material for several contemporary artists. Acrylic paint is a very recent discovery in the art world compared to oil paints and watercolours. Its versatile nature, vibrancy and stability have meant it has taken the art world by storm.
The more artists take advantage of the wide range of acrylic paints’ approaches, and the more acrylic paint products come to market. Want to know more about acrylic paint? Here we break down what it is, as well as its pros and cons.
What Is Acrylic Paint?
Acrylic paint is paint made of pigment that’s suspended in acrylic emulation. It is water-soluble and fast-drying and becomes water-resistant once dry. Acrylic paint is extremely versatile.
Depending on how much the paint is diluted with water or modified with acrylic gels, mediums or pastes, a finished acrylic painting can resemble a watercolour, gouache or oil painting. It can also have its unique characteristics not attainable with other media.
What Makes Acrylic Paint Different?
Before the 19th century, artists mixed their paints. This allowed them to achieve their desired colour and thickness and to control the use of fillers if any. However, with acrylic, hand mixing is generally not practical.
This is because of fast drying time and other technical issues, such as the necessity to combine several polymers and surfactants, plasticizers, defoamers, and stabilizers. So instead, artists purchase acrylic paint ready to go, modified using acrylic mediums or water.
The range of acrylic mediums is also greater than watercolour and oil. Acrylics can bond to many different surfaces, and mediums can modify their binding characteristics. Acrylics can be used on paper, canvas and a range of other materials, including hobby models like trains, cars and houses.
Faqs About Acrylic Paint You Use On Ceramic
Can You Paint Unglazed Ceramic Tile?
Choosing paint that matches the tile material and the bathroom surface is crucial. The ceramic, porcelain and unglazed quarry tiles can be painted with latex or epoxy paint in one-part (pre-mixed) or two-part (ready-to-mix) varieties.
How Do You Make Acrylic Paint Permanent On Ceramic?
Surfaces that are absorbent or porous are ideal for acrylic paint. Ceramics and glass will adhere to acrylic, but it will peel off easily if you let it dry. Ensure your ceramics stay acrylic-free by sealing them and using a baking method.
How Do You Paint Unglazed Porcelain?
Use a paintbrush or paint roller to apply alcohol- or shellac-based primer to the unglazed tile. Once the primer has dried completely, let it dry. Next, use a paintbrush or paint roller to apply alcohol- or shellac-based primer to the unglazed tile. Finally, spray your cleaning solution on the tile.
Does Acrylic Paint Work On Pottery?
With acrylic paint or fingernail polish, pottery artists can ornament pieces that do not require functional ornaments with any variety of other traditional paints. The most common method of applying fingernail polish is acrylic paint, but it can also be effective.
What Paint Will Stick To Ceramic Tile?
Using a high-adhesion primer to prepare the ceramic tile, latex, acrylic latex, and enamel paints will all work well. You should apply two to three even coats as needed until you are completely covered.
Can You Paint Porous Tile?
Painters can paint porous materials, such as wood and drywall. As a result, their pores help to grab the finish and hold it in place. However, in terms of painting, tile is not as effective as it could be due to several factors. As a first step, interior tiles, such as showers and bathtubs, are dense and either vitreous or impervious to water.
Can Ceramic Tiles Be Painted Over?
Before painting, ceramic tiles can be painted as long as they are not frequently exposed to water or heavy wear, repair chips, cracks, and other surface damage. To repair the damage with caulk or epoxy, follow the manufacturer’s instructions for drying.
Traditional Vs Modern Acrylic Paint
Although acrylic paint is relatively new in the art world, there is still referred to as ‘traditional’ acrylic paint and ‘modern’ acrylic paint. Traditional acrylic paints are the fast-drying paints that have been around for the last five decades and are made from brands such as Liquitex, Winsor and Newton, Golden and Grumbacher.
On the other hand, modern acrylic paints do not dry as quickly and can be reactivated after drying and are made from brands such as Golden and Chroma.
Pros And Cons Of Traditional Acrylic Paint
Toxicity Levels
- Advantages: acrylic paints are water-based, which means they can be thinned with just water (no toxic spirits are required). In addition, wet paint can be cleaned off brushes using just soap and water.
- Disadvantages: acrylic paints can contain toxins in their pigments, just like some oil paints. Additional toxins can be found in acrylics that use ‘retarder’ to slow down the drying time.
Drying Time
- Advantages: traditional acrylic paints dry rapidly, so there is no need to wait for layers to dry between painting sessions. Paintings are dry enough to ship safely within a day or so.
- Disadvantages: because acrylic paints dry quickly, they cannot be easily blended to create the ‘wet in wet’ technique popular with oil paints. For this reason, a finished acrylic painting can look harsh compared to a finished oil painting.
Reactivation
- Advantages: unlike watercolours (another water-based paint), once traditional acrylics are dry, they are on the support to stay. This makes painting new layers on top of previous ones simpler.
- Disadvantages: once the paint is dry, it cannot be removed or altered.
Durability
- Advantages: acrylic paints have been proven to be more flexible than oil paints. There is no need to follow fat over lean rules with acrylics so that they won’t crack.
- Disadvantages: we’ve only had 50 years of acrylic paints, so we can’t comment on how long they’ll hold up for.
Pros And Cons Of Modern Acrylic Paint
Toxicity Levels
Modern acrylic paints are water-based, which means no toxic spirits are required. Modern acrylics still contain mild levels of toxins, but they don’t use Retarders to slow drying time.
Drying Time
- Advantages: modern acrylic paints have extended drying times so that the paint can be left on a sealed palette and remain workable for several days. Also, wet-in-wet techniques can be used, just like oil paints, without a retarder.
- Disadvantages: you’ll need to wait between drying times. Modern acrylic paint won’t dry very quickly if you like your acrylics to dry very quickly.
Reactivation
- Advantages: modern acrylic paint reactivates. When water is applied to dry paint to the touch, it can be reactivated and worked into and/or lifted off.
- Disadvantages: over time, the ability to reactivate is eventually lost, and painting wet over dry acrylics may cause a colour bleed.
Durability
- Advantages: it appears that modern acrylic paint is more flexible and durable than oil paints.
- Disadvantages: modern acrylic paint is even younger than traditional acrylic paints. Efforts are being made to prove their longevity, but nothing can be irrefutably proven until sufficient time passes.
Weighing Up The Pros And Cons Of Acrylic Paint
Whether you are using traditional acrylic paint or modern acrylic paint, there are pros and cons compared with other paint mediums.
The Pros
- It’s versatile. You can paint on any surface that is oil and wax-free. This includes canvas, wood, paper, rocks, glass, fabric, cardboard, metal, and plastic. With the proper preparation, you can use acrylic paint on almost everything.
- It dries quickly. This allows you to finish your project faster.
- It’s water-soluble. You can wash it off your hands and brushes (while they’re still wet) with soap and water with no need for paint thinners.
- It’s less toxic and safer around children and pets.
- It’s more affordable.
- It’s flexible. You can mix acrylics with lots of different mediums to get different textures, adhere features, or change the drying time.
- It’s durable. As far as we know, acrylics are flexible and won’t crack, peel, or turn yellow.
- It’s vibrant.
- It’s water-resistant when dry.
The Cons
- Its colour becomes darker when dry, so the colour you paint with isn’t necessarily what you’ll end up with.
- It’s fast-drying, meaning you need to work quickly.
- It’s hard to remove from brushes, nails or clothing once dried. It’s best to keep a container of water near you while you’re painting to keep the brushes wet, so they are easy to clean. You should also wear protective clothing.
- It’s hard to remove from nails or clothing once dried.
- It’s considered by some art galleries and collectors as ‘not as valuable’ when compared with other paint mediums.
Understanding The Techniques Of Pouring Acrylics
While the practice of pouring artist paints is certainly not a new way to apply paint, achieving consistent results can be frustrating and costly. However, it is vital to the process to conduct experiments to understand the most critical controlling factors that preside over paint pours.
Studio Preparation
One sure way to improve the odds for successful pouring is to start with a clean studio.
Acrylic pours relatively slow drying paint layers, and dust can easily imbue into the film. Take some time to free the immediate workspace, sweep the floor, and wipe down surfaces around the studio. Next, be sure the tabletop or floor you are working on is also clean and level.
Even slight angles can cause issues with pours. Put down fresh poly plastic sheeting on the surface, which will protect the surface and help later on by preventing your artwork from becoming glued to the work surface, as pouring products creates puddles and drips that can travel off of the canvas or panel. Finally, control the temperature and humidity level in the studio as much as possible.
Dry climates increase the chance of crazes developing – fissures resulting from liquid acrylic products skinning over during initial drying while the underlying liquid paint is still very fresh. The skin shrinks and tears apart, resulting in unwanted physical textures known as a “craze” (see Image 1).
Painting Substrates
The most predictable painting surface for pours is a sealed panel. This surface is less affected by the wet product’s weight than stretched canvas. Of course, the panel needs to be resistant to warping from water; thus, sealing the surface with one or more coats of acrylic medium (or paint) is helpful.
Conversely, this advice may be counter-productive if your technique relies upon the surface absorbency and/or the ability to curve the substrate to control the painting movement.
This is why testing is critical even when using products that other artists find successful. If working on stretched canvas is vital to your process, you may be able to eliminate the sagging by stretching over a wooden panel or using a cardboard block between the stretcher bars.
Paints And Mediums Used For Pouring Applications
Free-flowing liquid paints and mediums are at the heart of the pouring process. Adjusting the viscosity and flow rate to work in tandem with how you want the paints to interact with each other is key.
Products like GOLDEN Fluid Acrylics and High Flow Acrylics are more practical when doing pours than thicker Heavy Body Acrylics. This is not to say you cannot use Heavy Body paints, but they will first require thinning with water, acrylic medium, or both.
A great approach for thinning Heavy Body paints without losing film strength is to first mix a thin acrylic medium such as GAC 100 with water (1 part medium to 1.5 parts water, and then use this mixture to thin the paints as much as desired).
This mixture assures quick thinning but contains enough acrylic binder so that you still end up with a pourable paint instead of a colour stain mixture. Since Fluids and High Flow Acrylics are already pourable, this step isn’t required to work with them, but sometimes it is necessary to adjust these paints. GOLDEN Airbrush Transparent Extender is also a valuable medium for adjusting paints.
This product is similar to High Flow Acrylics, containing flow improvers and levelling additives.
Although most acrylic mediums are inherently pourable, some are better suited for pouring. GAC 800 is a medium specifically produced to modify paints for pouring, such as when pouring a puddle onto a painted surface.
The GAC 800 mixes readily with the Fluid Acrylics, and this combination is the least likely to craze during drying. It’s still possible GAC 800 may craze, but this is usually the result of too much paint being added and, in turn, countering the acrylic solids level or the pour has been applied in too thick of a layer. A great starting point is to mix 1 part of paint into ten parts GAC 800 and limit the thickness to how far the product will spread.
In other words, pour the product into a pancake puddle, and let it seek its thickness without impeding its flow by using a taped off or dammed edge.
Once these tests are done, you may want to try other paint amounts and use edges to control the flow, but be wary of too thick of a pour to start. The biggest negative attribute of GAC 800 is “dry state clarity”. This medium retains a slightly cloudy quality making it a poor choice as a clear topcoat or even transparent colour layer.
Other mediums to experiment with include GAC 500, Polymer Medium (Gloss), Fluid Matte Medium, Self-Leveling Clear Gel and Clear Tar Gel.
One important note worth mentioning is that these products were not developed with defect-free pouring in mind, and although smooth thin layers are possible when using them, they are not free of issues and limitations. For example, a common misconception is that Self-Leveling Clear Gel can be poured liberally and spread around with palette knives, trowels and squeegees and level perfectly upon drying.
This is not the case, and some tool marks, however slight, will likely remain in the dried layer. Tool shape and application technique are critical to their success. Artists who have mastered their use have spent many frustrating nights in their studio figuring out the best application method that provides the desired results.
To start, use clean, large tools with smooth edges and carefully spread the product in multiple thin coats until the desired effect is attained. Allow one to three days drying between coats to reduce the chance of crazing. Don’t be put off if every layer isn’t a perfect epoxy like surface, as perfection is nearly impossible to attain in layers of air drying products.
Pouring Application Techniques
There are as many methods as there are product combinations to try. First, appreciate each paint colour as its unique formula and pigments vary in their density and ability to move and spread.
The same is true for the many acrylic mediums produced. Now factor in the addition of water, Retarder, or diluted Acrylic Flow Release. Tossing in the impact of the painting substrate and studio environment, suddenly, predictable pouring seems unattainable.
The way to best describe the approach to pouring applications is the concept of setting the stage to allow the products to do what they want to do; in other words, controlled chaos.
And if you don’t take good studio notes to identify how each painting is created, then you’ll never be able to reproduce a great effect when they happen. That said, here are some common methods and beginning mixtures to try out:
Thinned Color Washes
High Flow Acrylics are ready to use for this application. The colours will readily move and interact. Try them neatly, mixed with mediums like Airbrush Transparent Extender or GAC 500 and let gravity move them around.
Fluid Acrylics will require at least 10% addition with water to allow them to move about freely. Note: high additions of water increase surface tension, which can be countered by adding in 2 or 3% Acrylic Flow Release into the water before using it to thin paints. Do not over-add Acrylic Flow Release as it does not help improve flow, it’s intended to reduce surface tension which happens quickly.
Solid Color Pours
As mentioned previously, GAC 800 is a great medium to use with Fluid Acrylics for making coloured pours (see Image 2). Ideally, start around ten parts GAC 800 to 1 part Fluid Acrylic, mix and store the paint overnight in a sealed container.
This allows the bubbles incurred during mixing to rise and pop, resulting in clean pours with sharp edges. These mixtures produce clear colour edges. A solid colour can be used over an entire canvas, but avoid damming up the edges during drying.
Adding Isopropyl Alcohol Into Acrylic Paint
Alcohol is less dense than water and evaporates quickly once it hits the surface of a pour. Unlike other applications, the alcohol amount for this technique is relatively low.
Once the effect happens and it escapes the fresh pour, there needs to be sufficient time for the normal acrylic paint curing process to avoid film formation issues.
An effective starting recipe is two parts GAC 800, 1 part High Flow Acrylic, and 1 part 70% isopropyl alcohol. Create three or more paint mixtures in containers that can be shaken without spilling and carefully pour one colour on top of another. Dense pigments like Titanium White should be used as the final layers so that the more aggressive colours below will push up through and create the cellular effects.
Conclusion
As with any new painting technique, do not be discouraged if the desired results aren’t immediately. Good note-taking is critical for successful pours of acrylic paints and mediums.
