Item(s) in Stock | Usually dispatched within 24 hours

Seal-Dit is made from a blend of food grade waxes and specifically designed to serve as a non-toxic sealer. 

Seal porous objects made from wood, plaster, cloth, paper and even some seashells before applying silicone mould making materials using Seal-Dit. If left unsealed, the silicone will find its way into the microscopic pores in the surface and become mechanically locked in the surface. As a result, the object will have to be literally ripped out of the mould ruining the mould and perhaps the object being moulded.
