Product description

Kneadatite Blue/Yellow is a room-temperature curing, two-part epoxy sealant for all types of interior and exterior maintenance and repairs. When properly mixed together to a uniform green color, it forms an industrial-strength pol ymer compound for repair, modeling, and sculpting. Kneadatite Blue/Yellow’s consistency (like modeling clay) eliminates drips and runs, facilitates adhesion to the substrate, and allows shaping before cure begins. Once cured, it can be sawed, drilled, carved, sanded, and painted.

Basic uses

Use Kneadatite Blue/Yellow to make underwater pool repairs, repair cracks in pipes and tanks, fill small automobile dents, form custom gaskets, attach signs, hang light fixtures, repair stripped screw holes, and much, much more.

Nicknamed “Green” by sculptors, Kneadatite Blue/Yellow is well known for its long work life, non-grainy texture, and its ability to hold fine detail. Cured models withstand the heat and pressure of up to 4 vulcanizations in the mold- making process for castings. Sculptors using this product will find helpful tips and information in our Sculptor’s Information Sheet available on our website at

How to use

Surface preparation: Before applying, roughen and clean the area to be repaired.

Mixing and application: Wear impermeable gloves when mixing or handling uncured product.

Tape - Cut or twist off equal lengths of flat blue and yellow tape. Bars - Cut or twist off 1 part curing agent (blue) to 1.5 parts base (yellow). Mix by twisting and kneading with gloved fingers to a uniform color. For best results, use damp fingers for easier mixing and application.

Apply to the surface to be repaired within1 hour of mixing. Force into cracks or holes and remove excess material before hardening begins, preferably with a tool moistened with water. When applying to a damp or wet area, work the material forcefully into the surface and apply pressure until adhesion begins to take effect.

Kneadatite Blue/Yellow has a 1-1/2 to 2-hour work life. Functional cure occurs after 4 to 5 hours, when the application can be drilled, carved, sawed, sanded, and painted. Ultimate hardness is reached in 20 to 24 hours.

Shelf life: Tape - One year minimum from date of shipment when stored in original, unopened container at 75 ̊F (24 ̊C). Bars - Two years minimum from date of shipment when stored in original, unopened container at 75 ̊F (24 ̊C)
