Watercolor and oil painters also use various mediums, but the range of acrylic mediums is much greater. Acrylics have the ability to bond to many different surfaces, and mediums can be used to modify their binding characteristics. In these cases, it is recommended that the surface first be sealed with an appropriate sealer. Acrylics can be applied in thin layers or washes to create effects that resemble watercolors and other water-based mediums. They can also be used to build thick layers of paint — gel and molding paste are sometimes used to create paintings with relief features. Acrylic paints are also used in hobbies such as trains, cars, houses, DIY projects, and human models.
People who make such models use acrylic paint to build facial features on dolls or raised details on other types of models. Wet acrylic paint is easily removed from paintbrushes and skin with water, whereas oil paints require the use of a hydrocarbon. You should apply varnish to wood after painting with acrylics.
Sealing painted wood surfaces with varnish is the standard procedure. Changing the color or adding a glossy finish can completely alter the appearance of wooden objects. In addition to wood, varnish can be applied to many other surfaces. The best type of varnish for wood is polymer varnish. The varnish should be applied in two coats and allowed to dry for a day or two between each coat.
To protect acrylic paint on wood, you'll need to apply a clear sealant. Choose a wax-based sealant for a flat finish or a polycrylic sealant for a glossier finish. Once the paint has dried on your wood surface, apply a thin layer of your sealant with a dampened sponge, cloth, or paintbrush.
When it's dried to the touch, apply a second coat of sealant to improve its protection. Although the sealant might dry within hours, you'll need to wait 2-3 weeks before it's fully cured. Avoid putting anything on the surface during this time, since it can cause damage or imperfections. You can use it to paint on paper, canvas, wood, porcelain, and yes, even glass. Wait at least 2 hours in between coats and apply between 2 and 4 total coats of polycrylic to finish sealing your painting. Various types of varnishes protect acrylic paintings from dirt, light, moisture and discoloration.
Varnish is the standard go-to for sealing painted wood surfaces. It can completely transform a wooden object's appearance, changing the color tone or adding a glossy finish. However, you can seal other surfaces with varnish too.
Acrylic paint is a fast-drying paint made of pigment suspended in acrylic polymer emulsion and plasticizers, silicone oils, defoamers, stabilizers, or metal soaps. Most acrylic paints are water-based, but become water-resistant when dry. Versatile acrylic paint lends itself to surfaces ranging from cloth to glass to leather, but artists most commonly use acrylics to create paintings on canvas. So prepare the wood for acrylic painting by applying two or more coats of the sealer. Opt to prime all surfaces, including the back and sides, for a clean white professional look. However, all you really need to do is prime the panel face that will be painted.
To summarize you want to seal all exposed areas of wood, but priming can be just applied to the front face. To make acrylic paint waterproof, you will need to apply a sealer such as a varnish, for example. There are spray sealers that are the most commonly used in the art world.
The sealer will protect the coat of acrylic paint from the elements. I like to either use an acrylic sealer or a varnish to seal my acrylic paints. When waterproofing acrylic paintings on canvas, you should apply a sealer to finish the job. Acrylics are typically applied to canvases before priming.
If the surface is not primed, you can use Gesso primer. You can begin creating your art piece once the primer is dry. It usually takes 15–20 minutes for one to two layers of acrylic paint to dry. The rapid drying of acrylic paint tends to discourage blending of color and use of wet-in-wet technique as in oil painting. You may be unsuccessful however, because the wooden beads were not sealed before applying the water based paint, so there is nothing for the paint to stick to.
Importantly, you need to consider precautions and safety measures given when painting with acrylic paint to avoid contamination and health. Make sure your acrylic painting is dry before applying the varnish sealer. If you're waterproofing an acrylic painting on canvas, you'll want to add a sealer to complete the project. Most canvases are pre-primed to hold acrylics to the surface.
You can use a Gesso primer to prepare an un-primed surface. When the primer is dry, the canvas is ready for you to create your art piece. To protect acrylic paint on wood, you'll need to apply a clear sealant. In other words, if you don't properly finish your paint project with an outdoor acrylic paint sealer, the paint will wash off when exposed to the elements. While the paint might stick to your painting surface, if it's exposed to water before it's completely dry, the paint will wash off.
Another difference between oil and acrylic paints is the versatility offered by acrylic paints. Acrylics are very useful in mixed media, allowing the use of pastel , charcoal and pen on top of the dried acrylic painted surface. Mixing other bodies into the acrylic is possible—sand, rice, and even pasta may be incorporated in the artwork.
This versatility is also illustrated by the variety of additional artistic uses for acrylics. Specialized acrylics have been manufactured and used for linoblock printing , face painting, airbrushing, watercolor-like techniques, and fabric screen printing. The main practical difference between most acrylics and oil paints is the inherent drying time. Oils allow for more time to blend colors and apply even glazes over underpaintings. This slow-drying aspect of oil can be seen as an advantage for certain techniques, but it impedes an artist trying to work quickly.
The fast evaporation of water from regular acrylic paint films can be slowed with the use of acrylic retarders. Retarders are generally glycol or glycerin-based additives. The addition of a retarder slows the evaporation rate of the water.
For this reason, acrylics do not lend themselves to the color lifting techniques of gum arabic-based watercolor paints. Instead, the paint is applied in layers, sometimes diluting with water or acrylic medium to allow layers underneath to partially show through. Using an acrylic medium gives the paint more of a rich and glossy appearance, whereas using water makes the paint look more like watercolor and have a matte finish.
Priming the canvas before painting with acrylics will help seal your painting even more. You can use any of these finishes for waterproofing; a waterproof glaze, polycrylic finish, acrylic resin, or polymer varnishes. As long as the painting is completely cured, either will work. A number of people have reported using PVA glue as a sealant on their acrylic paints to try and provide their artwork with some protection against water. As you can imagine, once the PVA starts to peel it can pull parts of your acrylic paint off your canvas or paper too. Clear polyurethane coating, clear acrylic spray paint and lacquer spray sealers -- all waterproof paper.
These sprays are relatively inexpensive and available in various finishes, such as matte, satin, glossy and high-gloss. A matte finish has no gloss; satin finishes have a pearl-like sheen; and glossy finishes have a shiny surface. I was intentionally looking for a non yellowing varnish/clear coat that didn't have solvents or harsh chemicals that are yellowing my acylic white primer/paint.
Durable enough to protect from traffic with uv stability. Then I use rustoleum 2x spray colors on top of my acylic, so a clear finish that is compatible with acylic & spraypaint. I wanted a 2-3 day outdoor finished job, or I give up on a sealer.
To go with a complete acrylic system to rush the curing time may help. I've only come across acrylic ureathanes, or something as durable as Bona HD floor coating, but it seems to expensive. The only other system that works is a breathable hard wearing sealer, as used on stains which breath & last decades.
In other words, if you don't properly finish your paint project with an outdoor acrylic paint sealer, the paint will wash off when exposed to the elements. While the paint might stick to your painting surface, if it's exposed to water before it's completely dry, the paint will wash off. You'll use a clear sealer, like a polycrylic, to seal the paint on wood. I like to use Minwax Polycrylic Protective Finish to seal all of my projects.
I apply with a nice paintbrush and let dry between coats. Acrylic paints may be all that hard and robust when it's dry, but a little water spill could ruin the paint on the plastic. Moreover, acrylic paints are not waterproof – they are only resistant to water to an extent because it's a polymer. So it can absorb little water, which is why you need to seal the paint.
Additionally, they don't usually hold up well to severe, frequent handling, as other paints. They also work better on surfaces that are aerated like wood than plastic. Before we get into the specifics of waterproofing acrylic paint, it's important to first have a basic understanding of what this type of paint is and how it works. Acrylics are water-based paints that consist of a pigment suspended in a polymer emulsion. This means that when they are wet, they appear glossy and translucent; but once they dry, they become opaque and relatively hard.
To waterproof acrylic paints, they will need to be painted over with a special kind of varnish. This varnish is a unique form of acrylic gloss that adds a protective coating over the paint – protecting the pores against absorbing more water. The other way to Seal your acrylic paints is with a varnish. If you want to seal painted wood then this is the way to go. But you can seal any other painted project with varnish too.
It is a gloss varnish for sealing wood and a wide range of paints including acrylic paints. It will make applying the varnish quite a lot easier. While you may not need to prime or prepare all surfaces for painting with acrylics, it's often best to do so if you're working with varnishes. Sealing the paint with either a sealer or a varnish allows your art to hold up against water damage.
Can You Make Acrylic Paint Waterproof However, the type of sealant you choose may depend on your project. You'll use a clear sealer, like a polycrylic, to seal the paint on wood. On top of this, some hairspray formulas may causes issues with your paints and start to break them down and potentially ruin your artwork. Acrylic paints are water-soluble, so using a sealant will prevent your surface from being exposed to moisture and it'll help protect the color of the paint too.
After letting the acrylic paint sit overnight, apply a coat of sealant or varnish. Brush a thin coat of glossy acrylic medium sealant onto the wood using a dampened sponge or paintbrush. Metals are another popular surface that many have outdoors. If you would like to use acrylic paints on metal products, you can give a single coat of protective finish to give the paint longer to wear.
Metal objects that you may wish to paint could include garden signs or metal artwork in various outdoor shapes . Many will find metal watering cans and paint artwork on them to display outdoors.

Paint can be applied to water sealers, but the drying time of the sealer itself is the most important part of this task. For best results, prime the water-sealed wood first. Use either a latex-based or an oil-based primer as your first coat of paint before applying the finishing coat. An acrylic sealer like varnish will seal acrylic paint on your plastic and protect the layer from damages. The varnish is a durable finish that you can use to protect a painted material.
