If the paint has a strong chemical odour, it’s very likely to be solvent based. Water based spray paint usually has little to no odour. Is water based spray paint safe for children?

Water-based Paints - Advantages and Disadvantages Water-based Paints - Advantages and Disadvantages

You need to set your device differently, depending on the spray system. On HVLP devices, the parameters to be adjusted are the air flow and the volume of material, while on airless devices it is the pressure level. Water moisture in the air can also interact with the solvent from your matte varnish spray as it travels toward your model, creating an uneven coated surface Simply put, water based spray paint is a new technology. This makes it more expensive to produce in scale compared to traditional solvent based paint. After 15 years and countless cans of spray paint, I built Graff Storm to share what I’ve learned about graffiti culture with the world.Sealing your miniatures with a high quality varnish is the final step to a completed paint job. You’ll be happy you took the time to protect your models! They will look great for photographs, too! Water-based polyurethanes provide a clear, neutral finish and have low odor. You can recoat them in two hours and clean your tools with water. If you start early enough in the day, you can apply the recommended four coats and sleep in the room that night. If anything, adding that extra layer of gloss varnish may reduce the amount of detail and color that shows through the final coating. Each layer of varnish reduces the “clarity” of the paint job underneath. As a routine procedure, I try to apply no more than 3-4 layers of any varnish. How to Prevent the “Cloudy” or “Frosted” Appearance When Applying a Matte Varnish Water moisture in the air may be absorbed into your acrylic paint (on your miniature), which then interacts with how the matte varnish coats your model. Acrylic paint loves to absorb water (even when you think its dry).

However, if the solvent dries poorly (e.g., absorbed into the paint underneath or mixes with ambient moisture) the dry particulates previously in solution clump-up. This clumping, congealing, or aggregation of the powder-like substances in the matte varnish cause the cloudy, frost effect that obscures the paint job underneath. By using a gloss medium first (no particulates), you reduce the risk of the matte varnish appearing as a cloudy surface. The dreaded “frosted” look with poorly applied matte varnish. The cloudy appearance reduces contrast and color saturation. It’s an unfortunate adverse effect of using matte varnishes without proper conditions (see more about how to prevent and solve this issue below). The Reason You Don’t Want to Use a Gloss Varnish The best matte varnishes are spray-on type sealants, such as Testors Dullcote. Overall, the best clear coat for miniatures for gameplay or display are those you can spray with even layers that enhance contrast and protects surface detail.New Luxury & Gift Brands A-Z Kids Clearance Online Gift Vouchers Newsletter Stores Online Exclusives

Guide - Spraying varnishes: Our instructions and tips | WAGNER

Disadvantage of water-based varnishes: The disadvantage of water-based varnishes is that they are essentially acrylic mediums (with suspended dry particulates). This means they aren’t very different in composition to the paint you used to paint your miniatures. So, the varnish won’t be as durable or long-lasting as an enamel-based spray varnish like Testors Dullcote. It can be relatively easy to rub-off a water-based varnish (just soak a cotton tip in water and scrub). Solvent based paints are more tolerant of adverse weather conditions during the curing process. Water-based paints take longer to dry in high humidity and lower temperatures. Indicated below are instructional videos we have for preparing a surface for a new coat of paint or finish: All General Finishes water-based topcoats and wood stains are ready to spray from the container without additives with the exception of Conversion Varnish. Always strain material through a medium to fine mesh filter before spraying. If necessary, in hot or dry climates, reduce 10 to 15% with General Finishes Extender to extend the open time. PRE SEALING: This makes them much easier to use for long spray painting sessions or situations where the strong smell of solvent may be a problem – such as painting indoors. 4. Better for indoor useNote: An alternative to Testors Dullcote, if it is unavailable, is Tamiya Clear Flat Spray. Tamiya produces a similar matte finish). Spray-on Testors Dullcote enamel varnish Despite the many benefits of water based spray paint, there are also some issues which make traditional solvent based formulas a better option. For example: 1. Expensive You could be paying over double the price for a water based spray can compared to a non-water based formula. Most choose not to pay the premium because the benefits don’t justify the current price. 2. Colours may appear less vivid Spray paints that use a water based formula have little to no odour compared to traditional solvent and oil based spray paints.

If you can cool your aerosol spray varnish down (~12C or 53F) before spraying it, this will also help prevent the frosted effect. Hey! No true difference here. Just make sure to apply it the way I suggest in the article (good ambient temp and humidity) and allow to dry before handling. Water-based finishes are more sensitive to temperature and humidity than their oil cousins. It's best to apply your water-based poly when the air temperature is between 70 and 80 degrees F and the humidity is below 70 percent. If the air is both hot and dry, the poly may set so fast that it will be difficult to maintain a wet edge as you brush, or the film may not level properly before it sets.Initially on launch water based took longer to dry than solvent based paints especially in high humidity and lower temperatures. As water based technology is increasing this drying gap has been reduced to virtually the same as solvents and water based paints do es have the advantage of retaining sheen throughout its lifetime. This makes them much more environmentally friendly as water based formulas contribute less to greenhouse gas emissions. 3.
