What is so special about your molds?

We uniquely use different plastics with a variety of thicknesses in order to create the best molds possible. The characteristics of each plastic influence the workability, level of detail captured, and costs for each mold. Many manufacturers use the same plastic for all their molds, but this is extremely limiting from our experience. Just as each casting does best with a particular mix, each mold does best with a particular plastic. Moreover, if for any reason you prefer a particular plastic for a mold, you can always contact us and we will do our best to accommodate you.


What are your molds made of?

All of our molds are made of either our black ABS or our clear polyethylene plastic. The plastic we use for each mold varies and depends on what works best for each particular mold. Please email us if you have a special request as to the type of plastic being used with your order, and we will do our best to accommodate you.


What kind of materials can be used in your molds?

Our molds can cast plaster, concrete, resin, cement, and wax. Because our plastic is not food grade, we do not recommend casting candy or other foodstuffs in them. Proper release is needed for all molds depending on the casting material being used.


Why do your molds come in different thicknesses?

As mentioned here, we use the plastic that is best suited to each mold. Thinner plastic often works better for molds that need to be more flexible to improve workability, enhance detail, and lower the cost. Thicker plastic is often necessary to hold the form for heavier castings and to withstand the demands of repeated castings such as with our stepping stones and bench molds.


Are your molds reusable?

Yes. With proper use and storage, our molds will cast many times and last for years. The most important consideration is that the molds are protected from direct sunlight.


Do the molds need a release?

Yes. When casting plaster or concrete, we suggest using a nonstick cooking spray. For casting resin or other materials such as wax or soap, we recommend Armor All Wax. Cooking spray will not work well with these materials.


With either of these releases, you should wipe out any excess after spraying with a paper towel to prevent pitting in the casting.


What is the best mix to use?

For outdoor use, we suggest having a few mixes available since all molds are different and the correct mix for the type of molds you purchase is essential to casting successfully. Our plastic molds over 1/2" thick can be cast with a regular concrete mix such as Quikrete. Molds under 1/2" thick should be cast with either your own mix of sand and cement or a fast setting mix such as Rapid Set Cement or USG Hydro-Stone Gypsum Cement. If you want to cast with plaster for indoor use, we suggest USG No. 1 Pottery Plaster.


What are your molds made of?

We use ABS and polyethylene plastics ranging in thickness from .060” to 3/16”. Due to the large variety of molds we sell, the thickness of plastic we use varies and depends on what works best for each particular mold.

How To

How do I paint my statues and plaques?

We often recommend dry brushing for beginners as a quick and easy way to paint castings. You can paint the entire casting one color before applying this method or just use the dry brush method alone. Flat latex exterior house paint makes a great base coat. Just make sure that the base coat on your statue is thoroughly dry before brushing with another color if you are painting the statue first. You can thin the paint out with a bit of water if it seems too thick to get into crevices. The color you choose to dry brush with will depend on your base coat and the contrast you want. Some nice color combinations to try are black and silver, black and green, black and copper, and white and gold (what about white alone?).


Patio Paint is perfect for dry brushing and is available in an assortment of colors including many metallics. When you're ready to dry brush, start off by pouring a small amount of paint on a piece of cardboard that will serve as your palette. Then dip your brush in the paint and wipe a bit off on your palette before applying it to your piece. This method will create a professional finish that helps hide many of the flaws that come with concrete casting.


Concrete water-based stain, dyes, pigments, and sealers are another great option. These are easy to use and provide a durable and attractive finish. Oftentimes, you can either put the stain directly on your piece once it is out of the mold or apply it to the mix before filling the mold. Just make sure to follow the manufacturer's directions for the option you choose. Applying it directly to the concrete will usually give you a much deeper color and better coverage. You can also try dry brushing after using one of these methods to bring out even more detail in your castings provided that the manufacturer doesn't advise otherwise.


How do I clean the molds?

Molds should be cleaned immediately after removing the casting. A gentle scouring pad with dish soap and a good rinse works well. Waiting longer causes the concrete residue to harden and makes the molds much more challenging to clean.


How do I prevent air bubbles in my castings?

A simple way to avoid bubbles is to fill your mold 1/3 of the way full with your mix. Then jiggle and tap the mold and notice the bubbles rising to the surface. You won't get all of the bubbles; just try to get most of them. Fill your mold another 1/3 of the way using this same technique to remove the bubbles again. Repeat one final time after filling your mold to the top. This should eliminate most of the bubbles in your castings.


How long should I let my molds set when filled with concrete?

There is no set time because there are many factors to take into consideration when casting. Normal set time is about 24 hours for regular concrete or a cement and sand mix. However, this time will vary depending on the brand, time of the year, amount of water, and other factors involved. For example, using water treated with a water softener can cause issues with the setting up of the mix. Fast setting cement such as Rapid Set Cement will usually be ready to take out of the mold within 2–3 hours. There are several more kinds, but this is a wonderful mix for thin or more delicate castings. This cement is especially great to use with our smaller latex molds and thinner casting plastic molds. There are many premixed concrete and cement mixes available. You might experiment with a few of them to decide what works best for you instead of mixing your own.


Hypertufa is one such mix that is fun to work with and gives its own unique look when finished.
