EPs foam coating with spray on polyurea

Polyurea coatings is a relatively new class of industrial coating,
usually applied by spray using specialised equipment and
characterised by extremely fast drying and high performance

Polyurea spray system is relatively expensive, and we chose

to have our parts sprayed by a professional then to purchase

the system and spray it ourselves

Material is dry to touch in less then one min and is fully

curred in 24 hours. Polyurea can be sprayed to almost any

thickness - usually on foam - 3/8" are enough to provide

a strong hard finish
Polyurea can be used to create concrete molds to replace

labor intensive fiberglass molds

First step is to set an area where over-spray will not effect

any of your other equipment - once cured - there is almost

no way to remove the polyurea from any surface.
The next step is to clean the foam from dust and small

particles - and start spraying in thin layers - each layer

should be about 1/8"

At this point we can pour the concrete and once dry

can pop the part out and reuse as a mold again and again
