Best Polyurethane Materials for DIY Projects

Posted by EnvironMolds , Labels: , , , , , , , , , Friday, March 15, 2024 2:18 AM

Polyurethane is a key material in the DIY industry, which is constantly growing. It is renowned for its professional finish, durability, and adaptability, and can be used for anything from resin jewelry making to furniture restoration. But how does one choose the best polyurethane material for their project with so many options available? This blog explores the subtleties of polyurethane and provides advice on choosing the best product for many do-it-yourself projects like resin casting and mold-making.

Understanding Polyurethane

Fundamentally, polyurethane is a flexible synthetic resin that is highly regarded in the do-it-yourself community due to its resilience and versatility. It creates an unbeatable protective coating, which makes it the perfect option for a wide range of projects, from glossy resin jewelry production to finishing wooden furniture. There are two primary types of polyurethane: water-based and oil-based, both with special advantages for artisans.


Polyurethanes in Casting Resin Magic

Oil-Based Polyurethane

When delving into DIY projects that require a durable, enriching finish, especially on wood, oil-based polyurethane is a go-to option for many craftsmen and hobbyists. Its unique properties and application process make it suitable for a range of projects, from furniture restoration to floor finishing. Understanding its characteristics, advantages, and considerations can help you decide if it's the right choice for your project.

Characteristics and Benefits

Rich Finish: Oil-based polyurethane deeply penetrates wood, enhancing its natural patterns and color. This results in a warm, rich finish that can make even the most worn-out pieces look luxurious. Its depth of color and enhancement of the wood grain is a significant advantage for projects where aesthetic quality is paramount.

Durability: One of the most compelling reasons to choose oil-based polyurethane is its durability. It forms a hard, protective layer that is resistant to scratches, stains, and general wear. This makes it an ideal choice for high-traffic areas or furniture pieces that will be used daily.

Versatility: While oil-based polyurethane is particularly favored for wood projects, its versatility allows it to be used on a variety of materials. It can be applied over paint, fully cured epoxy, and other finishes, making it a flexible option for complex DIY projects.

Application Tips

Ventilation: Due to its strong odor and higher VOC content, ensuring good ventilation is crucial when working with oil-based polyurethane. Always work in a well-ventilated area or wear a respirator to avoid inhaling fumes.

Application Method: Oil-based polyurethane can be applied with a natural bristle brush, a foam brush, or a clean, lint-free cloth. Each method offers different advantages, but all require a steady hand and a methodical approach to ensure an even coat.

Drying Time: One of the trade-offs with oil-based polyurethane is its longer drying time compared to water-based alternatives. It typically requires 24 hours between coats, though this can vary based on humidity and temperature. This longer drying time can be a benefit, allowing more time for the polyurethane to level out, reducing brush marks and imperfections.

Finish Options: Oil-based polyurethane comes in various sheens, including gloss, semi-gloss, and satin. Choosing the right sheen depends on the desired aesthetic effect and the project's specific needs. For example, a glossy finish might be ideal for a dining table that you want to stand out, while a satin finish could be better for a bedroom floor that will see a lot of foot traffic.

Maintenance and Care

Maintaining the beauty and integrity of an oil-based polyurethane finish involves regular cleaning with a soft, damp cloth and avoiding harsh chemicals that can damage the surface. For floors and heavily used surfaces, periodic recoating every few years can help maintain the protective layer and keep the wood looking vibrant.


Secrets of Water Glass

Water-Based Polyurethane

In the realm of DIY projects, water-based polyurethane represents a modern, user-friendly solution that balances durability with environmental consciousness. Its formulation offers a myriad of benefits, making it a preferred choice for a wide array of applications, from furniture refurbishment to intricate artistic creations. Understanding its properties, advantages, and best practices for application can empower DIY enthusiasts to achieve professional-grade results with minimal hassle.

Properties and Advantages

Rapid Drying Time: One of the most significant advantages of water-based polyurethane is its quick drying time. Unlike its oil-based counterpart, which can take 24 hours or more to dry, water-based polyurethane often dries to the touch within hours, allowing for multiple coats to be applied in a single day. This rapid drying time accelerates project completion, a boon for both hobbyists and professionals alike.

Low Odor and VOC Content: Water-based polyurethane emits a significantly lower odor compared to oil-based varieties. Its low volatile organic compound (VOC) content makes it a healthier choice for indoor environments, reducing exposure to harmful chemicals during application and curing. This feature is particularly advantageous for projects undertaken in less ventilated spaces, ensuring a safer crafting experience.

Clear Finish: Unlike oil-based polyurethane, which can impart a warm amber hue to surfaces, water-based polyurethane dries clear, preserving the original color and grain of the material. This characteristic makes it ideal for projects where maintaining the material's natural appearance is desired, such as on light wood species or over vibrant paint colors.

Ease of Use and Cleanup: Water-based polyurethane can be easily applied with a brush, roller, or sprayer, making it versatile for various project types. Cleanup is straightforward, requiring only soap and water, which simplifies the process and minimizes the need for harsh chemical solvents.

Application Tips for Optimal Results

Surface Preparation: Proper preparation is crucial for achieving a smooth, flawless finish. Start by ensuring the project surface is clean, dry, and free of grease or dust. Sanding the surface with fine-grit sandpaper creates a smooth base that enhances adhesion, followed by a thorough wipe-down to remove sanding dust.

Application Technique: Apply thin, even coats of water-based polyurethane using a high-quality synthetic brush, foam brush, or a sprayer designed for water-based finishes. Avoid overworking the material to prevent bubbles and brush marks. Between coats, lightly sand the surface with fine-grit sandpaper to ensure a smooth finish and wipe away the dust before applying the next layer.

Environmental Conditions: Temperature and humidity can significantly affect the drying and curing times of water-based polyurethane. Ideal conditions are between 50-90°F (10-32°C) with moderate humidity. High humidity can slow drying times, while too low humidity may cause the polyurethane to dry too quickly, potentially leading to uneven application.

Curing Time: While water-based polyurethane dries quickly to the touch, it requires a longer period to fully cure. Allow the final coat to cure for several days before subjecting the surface to heavy use. Fully cured polyurethane provides a durable, protective finish that resists water, chemicals, and wear, preserving the beauty of the project for years to come.

Criteria for Choosing the Best Polyurethane

Durability: The endurance and robustness of your product may be impacted by your decision between oil-based and water-based polyurethane. Oil-based polyurethane might be a preferable option for furniture that will be subjected to a lot of wear and tear, like dining tables or floors.

Application Method: Your comfort level and the project's specifics can dictate whether you use a brush, spray, or pour-on application. Spraying polyurethane, for instance, is ideal for complex shapes and detailed work.

Aesthetics: The finish of the polyurethane (gloss, semi-gloss, satin, or matte) can significantly impact the look of the completed project. Consider the overall style and use of the item to determine the best finish.

Compatibility: Not all polyurethanes are suitable for every material. For example, certain types are better suited for wood, while others may be more compatible with materials used in mold-making and resin casting.

Best Polyurethane Materials for DIY Projects

Spray Polyurethane

Spray polyurethane stands out for its ease of application, making it an excellent choice for projects with intricate details or hard-to-reach areas. It's particularly useful in mold-making and resin casting, where a smooth, brush mark-free finish is crucial. Brands like Minwax® Helmsman® Spar Urethane offer spray versions that are durable and suitable for both indoor and outdoor projects, providing flexibility across various DIY endeavors.

Polyurethane for Outdoor Projects

For projects exposed to the elements, such as outdoor furniture or garden decorations, polyurethane formulated for outdoor use is essential. These products offer UV protection to prevent fading and are designed to withstand moisture, preventing wood rot and mold growth. An example is Varathane® Spar Urethane, which offers a water-resistant finish that's perfect for outdoor applications.

Application Tips for Best Results

Surface Preparation: Properly prepare the surface by sanding it smooth and ensuring it's free of dust and debris. This step is critical for both resin jewelry making and furniture refinishing, as it affects the final appearance and adhesion of the polyurethane.

Thin Layers: Apply polyurethane in thin, even layers, sanding lightly between coats once dry. This method reduces the risk of drips and brush marks, especially important in artistic resin techniques where the finish needs to be impeccable.

Safety: Always wear protective gear, such as gloves and a respirator mask, particularly when working with materials for life casting and resin casting, as these projects can involve more potent chemicals.

Making Plaster Work for Mold Making and Casting

Posted by EnvironMolds , Labels: , , , , Monday, January 16, 2023 11:15 PM

As we all know; plaster is a very versatile material. A modified version works well for making molds, casts and life casts. The trick is to use the right formulation from a reliable source to get best results.

Plaster is simply a mixture of sand with lime and cement. This soft white powder is mixed with water to create a workable paste that can be applied on different surfaces. It yields a smooth and hard surface finish when dry.

Primarily used as a construction material, plaster can form a protective or even decorative coating on walls, ceilings, etc. The same plaster has found its way into dentistry, orthopedics and other applications. What’s more, it lends itself well to arts like plaster casting, mold making and life casting too!

Indeed, this material can be used to make both molds and casts. Plaster molds serve as the base for industrial applications for making metal castings wherein molten metal is poured into the mold and allowed to harden to form the cast. When used as a casting material, it yields crisp details with an excellent finish. And plaster happens to be the material of choice for making life casts. Be it face, torso, hands, feet or the whole body, the stark relief of a bright white plaster cast stands unparalleled!

Additionally, plaster is infused into gauze that serves well for making shell molds. As the plaster turns stiff on drying, it helps reinforce flexible molds so that they can retain their shape without flopping during the casting process.

Some artists even use the same plaster bandages to make rough belly molds and masks. This captures the basic shape and form of the model without getting into too much detail.

How to use?


Mold making and casting artists should keep in mind that they cannot use regular plaster (or plaster of Paris). This will tend to turn chalky and flaky, not to mention that it fails to hold details well. A specially formulated form of plaster is considered better suited for mold making and casting applications.

Keep in mind that plaster cannot be used directly on the skin. The paste will emit heat as it cures which can even burn the skin. Therefore, it is better to stick to applications on inanimate objects. However, plaster infused bandages can still be used for making body molds.

What is important here is to use the right form of plaster. Take CastRite Art Casting Stone for instance – this comes from a trustworthy manufacturer and is considered the perfect choice for castings and life castings. It has been specially heat-treated and will set fairly hard, but can still be carved and tooled as desired. This fine arts casting stone also holds excellent detail without chipping, cracking or even becoming chalky. The plaster can be used for making castings in alginate, resin and silicone molds.

In sum, indulge in the goodness of plaster, but make sure to opt for the best option!

CastRite Art Casting Stone For Plaster Casts

Posted by EnvironMolds , Labels: , , , , , Tuesday, January 28, 2020 10:04 PM

A wide variety of plaster powders are available in the market – each with their own functions and properties. Choosing the right option for making a cast becomes difficult for novice artists.

The art world is choc-a-bloc with varied materials for making molds and casts. The choice ranges from simple clay, wax and plaster to more sophisticated options like resins, latex rubbers, silicone rubbers and more. Even when it comes to using plaster, mold makers and casting artists are often flummoxed whether they should use regular plaster of Paris or the more refined casting stone powders available in art stores.

Well, fact of the matter is that generic plaster tends to be chalky and fails to hold details well. Casts made from this powder will be prone to chipping and cracking too. On the other hand, casting stone powders are made with gypsum that is especially heat treated to make it suitable for fine art casting.




































CastRite Art Casting Stone is a top quality, high definition casting stone powder offered by EnvironMolds. It is a popular material of choice for making art castings of all types. It is easy to work with, gives a natural bright white finish, holds finishes well and is extremely durable.

The CastRite powder is a highly dense formula that is suitable for making casts from alginate, resin and silicone molds. It can be cast into plaster bandages as well. Apart from casts, it is also commonly used for making shell molds for latex slip castings and backup flexible molds. At times, fiberglass fiber is added to the mold powder for additional strength.

How to use?

Take 2 equal parts of CastRite Art Casting Stone powder and 1 part of water by volume. First pour the water into a mixing container and then add the casting stone powder very slowly. Mix with a stirring stick while scraping the sides and bottom of the container till the mixture becomes thick and creamy. The material is ready for pouring into the mold for making the cast. This formula inherently has minimum air bubbles; even these can be eliminated by rotating the mold slowly in all directions.

Making Perfect Casts From Molds

Posted by EnvironMolds , Labels: , , , Monday, June 17, 2019 3:59 AM

Mold making is deeply entwined with casting. In fact, it is impossible to make a cast without making a negative impression of the model in the form of a mold. Learning both the arts becomes essential.

The casting process always begins with how to make a mold. The artist can choose the mold making material and the technique depending on the nature of the model, the preferred casting material, personal dexterity and so on. While the mold can be made using clay, wax, plaster, resin or rubber, the method can vary from simple block molds to more complicated blanket molds using the brushed, poured or glove mold making system.

Here, the artist also has to decide whether they will be making a mold in its entirety at one go or in parts. The latter is quite an intricate and time-consuming process. But it becomes essential if the model has deep indentations, protrusions or undercuts. This calls for making keys and sprue holes in the parts of the mold as well.

Once the mold parts are ready, the artist can move to the casting process. First timers often wonder if the cast will also be made in parts and need to be fused together later.

This is not actually the case in reality. In fact, making a cast in multi-part molds is similar to casting in a single piece mold save for a few extra steps.

The casting process

The mold parts are thoroughly cleaned and dried before coating with a release agent. Then the parts will be lined up using the keys so that they align properly. Mold straps or heavy duty rubber bands are needed to bind the mold parts together and keep the casting material from leaking out. In case the mold is flexible, backing boards are placed on either end of the mold to keep the mold from bending or collapsing on itself. The bands go over the boards and hold the entire arrangement in place.

Now all that is required is pouring the casting material into the mold through the sprues. This should be done slowly to avoid air bubbles. The mold is tapped a few times to allow the plaster, rubber or resin to fill the indentations and settle everywhere properly. It is advisable to continue pouring till a bit of the material starts flowing out from the holes.

The mold should be allowed to sit for a couple of hours or even overnight to ensure proper curing. Once set, the bands can be removed and the mold parts separated with a gentle hand. This will reveal the cast in its entirety!

The cast is then removed and finished with sandpaper and paints as needed.

Therefore, newbies need to know how to make molds and casts of different types before attempting any project. Perfection comes with practice and they can learn the tricks through trial and error. Very soon they will also be able to create flawless casts from impeccable molds.
