Installation Instructions



The following procedures should be followed for optimum sealant performance.

  1. Clean the upper and lower joint surfaces with a stiff bristle brush.
  2. Remove any dirt, debris, flashing, or concrete high points, which could keep the joint from coming together.
  3. ConSeal recommends the use of surface primers (i.e. CS-50, CS-75, CS-300), as primers improve adhesion. When using a primer, allow the primer to dry before placing sealant. The primer will normally be dry to the touch within 15-20 minutes. (Note: Primer can be applied at the job site or at the plant several days in advance of the set.) See ConSeal’s Priming Installation Instructions for additional details.


  1. Place sealant on the tip of the spigot in the correct location (SEE FIG 1). (Note: CS-1550 Instant Grab Adhesive is designed to aid in the application of sealant in vertical and upside down installations like concrete pipe.)
  2. Join the sealant into one continuous strand by kneading the ends together where they meet. IMPORTANT: DO NOT STRETCH THE SEALANT. DO NOT OVERLAP THE SEALANT.
  3. Once the sealant is installed, DO NOT: STEP ON THE SEALANT OR ALLOW DIRT AND DEBRIS TO FALL ON THE SEALANT (Note: Plastic sheeting may be installed over the sealant if necessary.)
  4. A minimum compression of 50% is required. Greater than 50% compression is optimal. It may take 15-20 minutes for the sealant to fully compress. This will vary according to the ambient temperature and the weight being applied.
