Polytek's wide range of concrete mould making materials are available to make your own concrete moulds, formwork, textures and stamping pads. Through decades of research and development, Polytek is able to offer the most comprehensive selection of flexible mold materials for concrete casting applications.

-Polyurethane rubber -Silicone rubber -Latex -Plastic Melt Adhesive (Hot Melt)

These systems can be used to produce a variety of precast concrete products and are available in castable, brushable and sprayable options.

Casting stone application PU mould rubber

Liquid polyurethane or silicone rubber molding rubber. These mold rubbers reproduce surface details brilliantly, provide excellent dimensional stability, have an unmatched service life, and offer increased durability compared to hot melt and polypropylene systems. Polyurethane molds can be completed in less time than silicone rubber molds (about 16 hours demold time) Compared to latex rubber molds. If properly maintained, these molds will last for years, producing thousands of stones.

Decorative surface

Pour Polytek liquid rubber over textured patterns (such as slate, brick, cobblestone, flagstone, etc.) to make a reusable stamp tool and texture the skin to impart the desired texture to concrete floors, walls or other surfaces. Concrete stamping is used to make artificial stone walls, textured pool decks, walkways, patios, driveways, stairs, countertops and more mesa The entire shape and texture of the countertop can be created, or combined with rigid forms to create individual countertop elements. These include sink inserts, decorative trim and trim, drain boards, etc. background decoration Stones, rock wall linings, fire pits, retaining wall blocks, pier wall caps, etc.

Large scale building model Concrete: Hard Coating Polytek® polyurethane plastics can be used for hard coatings on hard surfaces such as EPS foam, low density machinable surrogate wood, MDF or wood. These two-component, room temperature curing systems are available in both brushable and sprayable options. The paint can be applied in one or more layers to create finished models or precast forms for concrete casting. Cured plastic is easy to sand or machine. EasyFlo Spray FR Liquid Plastic (5 sec gel time, cure hardness D72) Fast curing sprayable polyurethane system for hard coating hard surfaces such as cut EPS foam, MDF or wood or low density machinable surrogate wood. This thin, tough and easily sandable coating can be applied in one or more layers. This is a flame retardant product: UL-94 (V-0). EasyFlo Series Liquid Plastics and PolyFiber II The plastic can be sprayed with a PlakPak spray gun. For fast-curing brush-on hard coats, PolyFiber II thickeners are added to the EasyFlo line of liquid plastics to give these low-viscosity resins a brushable consistency. Use EasyFlo 60 or EasyFlo 95 (slower gel version) plastic. Architectural pattern reproduction (vertical face operation - painting or spraying) Polygel ® Series - These rubbers are easy to brush or spray after mixing and are used to make thin layers of mold softgel. The mixing ratio is 1:1, easy to operate, and the color can be adjusted according to needs. Good dimensional stability. Layer thicknesses can be stacked, and the next layer needs to be made to ensure that the previous thin layer has enough gel (usually about 1 hour), the ideal thickness of the mold thin layer is 1/8 to 3/8 inch.
