## Overview

Free Form Sculpt is a high-density, two-part epoxy dough that self-cures to a hard, durable finish without firing. It’s 30% lighter than similar products, holds vertical surfaces flawlessly, and offers a long 1.5-hour working time. Free of carcinogenic crystalline silica, it supports fine detail sculpting, custom coloring, and bonds to multiple surfaces—including underwater curing—making it the go-to choice for professional and hobbyist sculptors alike.

## Description

Free Form SCULPT is a two part sculptable epoxy clay that requires no firing and will self-cure in a short time to an extremely hard and durable state with virtually no shrinkage. SCULPT is 30% lighter than similar products and holds vertical surfaces better. Users can sculpt larger, stronger pieces with more control over weight distribution. Free Form SCULPT has an ultra fine particle size that gives the user the ability to sculpt finer detail with better precision using tools or shaping by hand. A mirror-like, gloss finish can be achieved by smoothing SCULPT with Free Form Detailer before it cures. Parts A & B are mixed in equal amounts by hand. Working time is a long 1.5 hours and Free Form SCULPT cures overnight to a hard, rigid epoxy that is very strong and waterproof. SCULPT is easily colored by adding SO-Strong color tints to create marble or other effects. Cured putty is easily painted with acrylic paints. Free Form SCULPT does not contain crystalline silica (which is a known carcinogen). It can be safely sanded, shaped, and painted. Used as a repair adhesive, Free Form SCULPT will bond to itself and a variety of surfaces including wood, metal, glass, stone, and concrete. Free Form SCULPT will even cure under water.

Review: Great for any project! - Great product!
Review: Solid as a rock! - I've been using this product for a long time. Initially it is sticky, and yes it can sag a little from the weight. No big deal. You learn to work with it. I carved a willie nelson bust out of oak which started cracking and checking bad. After sculpting everything over the oak, I was able to carve with ease. You can get great details after about 30 mins. I've even used it to laminate a block of wood to the the body of an eagle. No cracking or shrinking. This stuff is tough. I've sculpted in 114 heat and 40 degree cold. Never had a problem. I personally don't use gloves when mixing. I use 91% alcohol to clean my hands. It comes off quickly. I love that it can be smoothed with water and it dries to a gloss.
