Installation Guide

Important Note on Caulking:
Surface Prep: Cleanallsurfaces.Jointsmustbeclean,frost-free,andfreeofoil,greaseoranyothercontaminants.Avoidcontact
with alcohol and other solvent cleaners during cure. Use open cartridges the same day. Priming is not necessary for the application
of caulking to Genstone panels.
Application: Recommendedtemperaturesare40-100degreesFahrenheit.ForbestperformanceSikaFlexshouldbegunnedonto
thepositiveshiplapedgeofthepanelsnottoexceed1/2" ofthickness.Caulkingistobeappliedbetweenpanelsonthepositive

Applying Over Wood:

with the application of the grout.
Applying Over Exterior Gypsum Board:
Whenusing GenStone on anexterior gypsum board withthe use ofadhesiveproceed as inthe above described procedurefor
application over cement. Screws must be long enough to penetrate the panel and bite into the stud behind.. Additional screws are
needed as well where the panel overlaps a stud. It is possible depending on the stud layout of the wall that you may only cross over
two studs but if available shoot screws in each stud that the panel overlaps. At each stud a screw should be placed in the positive
ship lap and at least one in the grout joint on that same stud.
Applying to a Steel Building:

the same above procedure for applying to wood.

area clean and use the old piece as a template to cut out the new piece. Screw and or glue the replacement section in and paint and
caulk as necessary making sure that all areas are covered.

Maintenance and Cleaning:
GenStone panels require very little maintenance and should be cleaned using water or warm water, or warm water and a mild soap.
