Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal
forms of calcium carbonate (CaCO3).
Most limestone is com- posed of skeletal fragments of marine organisms such as coral or foraminifera.
Sealing limestone is highly recommended as stain removal can be limited due to its porosity and chemical sensitivity
LIMESTONE
SEALING & MAINTENANCE GUIDE
SEALING:
Sealing limestone prior to installation is highly recommended. Many Limestones contain soluble minerals and can
often become permanently discoloured from the installation process.
It is always best to consult with your stone supplier to verify whether your lime- stone requires this treatment. For best
results, sealing limestone on all six sides using Aqua Mix® ProBlock a minimum of 24 hours prior to installation.
PRE-SEALING:
If the stone does not require to be pre-sealed, it is generally recommended to apply a coat of sealer using Aqua Mix®
ProBlock on the surface prior to grouting. This is to act as a grout release and assist in the grout clean-up process.
PRE-GROUT SEALING (IF NOT PRE-SEALING):
If applying an Enhancing Sealer as the final surface seal,
DO NOT
apply ProBlock to the top surface as it will stop the
penetration of enhancing sealers. Please contact Artisan Exterior or Aqua Mix® prior to installation if an enhancer is
specified for use.
