What can I use for flexible concrete forms?
Hardboard is inexpensive form material and is easy to flex into smooth curves. Hardboard siding is intended for exterior walls, but it’s also great stuff for forming curves because it’s flexible and cheap.
Can I use Styrofoam as a concrete mold?
Foam is a very good material to use for undermount sink blockouts. It’s rigid enough to withstand the pressure of fresh concrete, but soft enough to be easily removed after casting without fear of cracking the concrete during blockout extraction.
How do you keep concrete from sticking to forms?
In some instances, concrete will naturally bond to other materials. To prevent concrete from sticking to these materials, you need to treat them with a release agent to keep the concrete from sticking by forming a thin lubricant film over the material. When the concrete is dry, it’s easy to separate.
What material does cement not stick to?

What is a road form?
Road forms are a quick and simple solution for concrete shuttering and are typically used for the forming of slabs, kerbs and concrete roads. The Fast-Form patented road form system is unique and unlike any other on the market.
What wood should I use for shuttering?
Commonly used by the construction industry in the formation of shuttering for casting concrete on site. Often used with plywood and OSB board. The timber used for this type of work is usually lower grade carcasing timber with a planed sawn edge (PSE).
Can you use MDF for concrete forms?
This MDF Bender Board product has a wide variety of applications. It can be used for curving concrete sidewalk forms as well as temporary landscape applications.
How do you make lightweight concrete with Styrofoam?
- Place 5 gallons of water into the concrete mixer.
- Add half a 94 lb.
- Add one of the 5 gallon buckets of Styrofoam beads.
- Continue adding the Styrofoam, taking the time to mix in each bucket after the addition to the cement mixture.
- Stop mixing the concrete when all the Styrofoam has been absorbed.
What material is used for concrete molds?
There are two main suppliers of urethane rubber for concrete molds: Smooth-On and Polytek. Both make polyurethane rubbers that come as two-part liquids (resin and hardener). Polytek recommends using a 74-45 or a 75-60 material for concrete countertops.
