A method for manufacturing marble-like products with combined cross section of synthetic
resin and cement or gypsum based layers |
(57) Two or more monolithic layers are applied in which the first main layer is based
on synthetic resin binders like epoxy resin (4) while the backing layers are composed
of a hydraulic binder type like cement, gypsum or anhydrite (6), are applied wet on
wet directly after each other. Intermediate layers of sprinkled sand or crushed stone
(8) may be used to increase bond between the two layers especially if the second layer
is to be applied for any reason after the setting time of the first layer. The moulds
(2) used for production can be made of metal, plastic, rubber or combinations thereof.
The product is stored at ambient room temperature or elevated temperatures until the
product cures before demoulding.
