5. INSTALLATION 
Preparation (Cont.) 
METAL 
Remove scale, rust and loose coatings from metal to expose a 
bright white surface. Any coatings on metal must be tested to 
verify adhesion of sealant or to determine an appropriate 
primer. 
Priming 
• ProSpec
®
 Stone Veneer Sealant is considered a non-priming 
sealant, but special circumstances or substrates may require 
a primer. It is the user’s responsibility to check the adhesion 
of the cured sealant on typical test joints at the project site 
before and during application. Consult Technical Service for 
additional information. 
Note: It is the responsibility of the installer/applicator to ensure the 
suitability of the product for its intended use. 
Application 
1. ProSpec
®
 Stone Veneer Sealant comes ready to use. Apply 
using professional grade caulking gun. Do not open 
cartridges until preparatory work has been completed. Trim 
cartridge at an angle to desired bead size and puncture inner 
seal. 
2. Fill joints from the deepest point to the surface by holding an 
appropriately sized nozzle against the back of the joint. 
3. Dry tooling is recommended. Proper tooling results in the 
correct bead shape, neat joints, and optimal adhesion. 
4. For roof tile applications apply a bead of Stone Veneer 
Sealant sufficient in size to make a bond between two tiles 
on the upper surface of the down slope tile. Install the 
upslope tile and press into the sealant bead to ensure good 
contact between the sealant and both tiles. 
Clean up 
1. Immediately after use, clean equipment with organic solvent 
or xylene. Use proper precautions when handling solvents. 
2. Remove cured sealant by cutting with a sharp-edged tool. 
3. Remove thin films by abrading. 
Limitations 
  Do not allow uncured ProSpec
®
 Stone Veneer Sealant to 
come into contact with alcohol-based materials, solvents, oil
-based caulking, uncured silicone sealants, polysulfides, or 
fillers impregnated with oil, asphalt or tar. 
• Protect unopened containers from heat and direct sunlight. 
• In cool or cold weather, store container at room temperature 
for at least 24 hours before using. 
  Do not apply over freshly treated wood; treated wood must 
have weathered for at least 6 months. 
  Do not use in swimming pools or other submerged 
conditions. 
• Substrates such as copper, stainless steel, and galvanized 
steel typically require the use of a primer. An adhesion test is 
recommended for any other questionable substrates. 
• ProSpec
®
 Stone Veneer Sealant is an aromatic urethane, as 
such it may discolor over time with UV exposure. 
• Apply in below freezing temperatures only if substrates are 
completely dry, free of moisture and clean. Contact Technical 
Service for more information. 
• Lower temperatures and humidities will extend curing times. 
• Pursuant to accepted industry standards and practices, using 
rigid paints and/or coatings over flexible sealants can result in 
a loss of adhesion of the applied paint and/or coating, due to 
the potential movement of the sealant. However, should 
painting and/or coating be desired it is required that the 
applicator of the paint and/or coating conduct on-site testing 
to determine compatibility and adhesion. 
  Proper application is the responsibility of the user. 
  Not for use in glazing applications. Do not apply on glass and 
plastic glazing panels. 
Curing 
The cure of ProSpec® Stone Veneer Sealant varies with 
temperature and humidity. The following times assume 75° F 
(24° C), 50% relative humidity, and a joint ½” width by ¼” deep 
(13 x 6 mm). 
• Skins: overnight or within 24 hours 
• Full cure: approximately 1 week
