• So that the last row of Pittsburgh Corning Glass Block units can be installed easily, cut the top perimeter channel in half lengthwise with a utility knife. Apply one bead of sealant. Install that half of the channel at the top of opening (Illus. B). On exterior applications, secure the exterior-side half of the channel with screws. The interior half of the channel will be sealed in place. A Q PERIMETER CHANNELS 6.
• Place the horizontal spacer on top of the first row of glass blocks (Illus. I). Remove any excess sealant. Adjust size of beads of sealant to prevent squeeze out (keep joint areas clean). If it’s necessary to have a joint in the end of the horizontal spacer to extend it, cut the spacers so that the joint is under a vertical spacer. Stagger these horizontal joints from end to end on each proceeding row of glass blocks.
K L 7. Seal The Joints Option 1 – Sealant Joints Finish: • Follow APPLICATION instructions on the glass block sealant tube to open the tube. Coverage rate is one tube per sixteen (16) blocks. The sealant skins over in 15-17 minutes. Don’t seal more joints than can be tooled in approximately 17 minutes. Practice the sealing technique before starting.
• After 48-hours remove any excess sealant from the glass block faces with a razor blade. • Clean channel surfaces and glass block faces with glass cleaner or soapy water. Do not use abrasive cleaners or steel wool which may damage the glass surface and sealant. • Install surrounding wood or other trim, if desired. Option 2 – Grouted Joint Finish: IMPORTANT: The ProVantage® Surface Grout was designed and tested for this application – DO NOT SUBSTITUTE! • Caution: Avoid contact with skin.
