Method for manufacturing a lightweight veneer system
A lightweight veneer system and method for producing a construction material that simulates the appearance of natural finishes such as stone, brick, or exposed concrete while providing improved technical characteristics. The system incorporates a precise sequence of mixing water, acrylic polyester resin, recycled ground glass, calcium carbonate, fiberglass, and iron oxides for coloration, followed by the addition of white or gray cement and plaster. The specialized process involves treating molds with release agents and pigments to ensure natural-looking textures and colors. The material is then poured into molds, vibrated to remove air pockets, and cured in a controlled environment to achieve optimal hardness and moisture content. The final product is significantly lighter than conventional materials, offering advantages in transportation and installation. This environmentally conscious method includes recycling of both water and defective materials back into the production process, emphasizing sustainability alongside industrial efficiency.
1 . A method for manufacturing a lightweight veneer, said method comprising:
a. introducing thirty-two liters (±10% tolerance) of water into a concrete mixer machine;
b. adding one kilogram (±5% tolerance) of acrylic polyester resin;
c. mixing for at least one minute;
d. adding 9 kg (±5% tolerance) of recycled ground glass;
e. mixing for at least one minute;
f. adding 6 kg (±10% tolerance) of calcium carbonate (marble dust);
g. mixing for at least one minute;
h. adding 30 grams (±10% tolerance) of fiberglass;
i. mixing for at least one minute;
j. adding 21.5 kg (±5% tolerance) of one of white cement or gray cement;
k. mixing for at least two minutes;
l. adding 9 kg (±10% tolerance) of masonry plaster;
m. mixing for at least thirty seconds; obtaining a final mixture
n. preparing molds with release agent;
o. transferring the final mixture into the molds within seven minutes, obtaining filled molds;
p. covering said filled molds with plastic, obtaining covered molds;
q. placing the covered molds in a primary curing area with controlled temperature (20 to 30 degrees Celsius) and humidity (50 to 60%);
r. letting stand the covered molds in the primary curing area for 24 hours;
s. placing the covered molds in a secondary curing area with controlled temperature (25 to 35 degrees Celsius) and humidity (50 to 60%);
t. letting stand the covered molds in the primary curing area for 48 hours, obtaining a final veneer; and
u. verifying moisture content of the final veneer, wherein if said moisture content is below 20%, the final veneer is considered ready for packaging, whereas if said moisture content is above 20% molds are covered with plastic again and placed in the secondary curing area with controlled temperature (25 to 35 degrees Celsius) and humidity (50 to 60%) for an additional 8 hours, repeating this step until said moisture content is below 20%.
2 . The method for manufacturing a lightweight veneer of claim 1 , further comprising after step n, the step of painting the molds with iron oxides in an irregular and sporadic manner to obtain a natural-looking finish.
3 . The method for manufacturing a lightweight veneer of claim 1 , further comprising after step u, the step of detecting and grounding down any faulty product obtaining grounded veneer, and reintroducing said grounded veneer into the production cycle in step d, in replacement of any quantity of recycled ground glass between 0 and 9 kg (±5% tolerance).
