Customize these with your personal Logo (see below for more information on this process) Available in 4 varieties. Select from the drop down menu above when ordering. Flexible, yet still rigid enough to support casting. Made of extremely durable polyurethane that can flex and stay strong. Good for hundreds of uses- Actually gets better with each use as the mold will season.

Mold Setup Concrete Sample Making Mold: Use of release on the rubber Mold is recommended. Apply a release agent that is safe for rubber (sold here) just prior to casting the concrete. The Sample Maker Molds are designed to simply be filled with concrete. Vibrate the Sample Maker and concrete to remove air pockets. Mold Removal: Cured concrete samples should easily remove from the rubber Molds. Any small bumps in the concrete can be lightly removed with 400 grit sandpaper or a Diamond Sanding Block. Mold Care: Most rubber products season from use with concrete, as the cement will fill small air holes in the rubber. Keep that in mind when cleaning the mold, as it may perform better left with some cement residue filling the imperfections in the rubber. Clean rubber Mold with a sponge or stiff brush after each use. Dried concrete can be removed by carefully scraping with a putty knife or wire brush. Difficult to clean molds can be scrubbed with a light muriatic acid wash (20 parts water to 1 part muriatic acid). Keep Rubber Molds out of direct sunlight to prolong their life. Re-apply release prior to each use. Want to Customize with your Logo? This can be done easily, by you. First, order the Sample Maker you want from the drop down menu above. Next, order Custom Logo Stamps (sold here), as many as you want. If you have the 4-Square Sample Maker Mold for example, you would probably want to order 4 identical logo stamps. We will ship the Sample Maker mold(s) to you, and we will make the Custom Logo Stamps and ship them to you separately. Once you receive them, you can trim the Logo Stamps as you desire, and then silicone them onto the rubber Sample Maker mold. If you want the logo pieces to be more permanently attached, make sure you clean the Sample Maker mold and even roughen up the area to glue the logo stamp with some rough sand paper before you glue/silicone the logo stamps in place.
