Application Information
Instructions for use


All porous surfaces should be primed with Vetoseal XX777-50 . The substrates should be dry before applying primer. Prime the sides of prepared joints with soft brush. Primer should be applied in thin uniform film. Allow to become tack free before applying the sealant. In order to keep the joint edges clean, use masking tape on the joint sides and remove immediately after finish sealant application.


The components of Vetoflex PS787 are supplied in the correct mixing ratio. Add the entire contents of the  hardener component into the base container and mix together thoroughly for three minutes using a slow speed drill (300 to 500 rpm) fitted with a suitable mixing paddle. Ensure any settlement is thoroughly dispersed. The sides of the container should then be scraped down to ensure that any unmixed components do not remain. Mixing should then continue for a further 2 minutes.


The mixed Vetoflex PS787 (PG) can be poured directly from the mixing container by compressing the sides to form a pouring lip. Pour into the prepared joint to the required level, should the joint width prohibit direct pouring from the container, the mixed material can be poured into a Vetoflex Barrel gun and applied to the joint. It may be necessary after a few minutes to top up the level of the sealant after it has flowed into all joint irregularities. Finally, strip off any masking tape that may have been used. When using gun grade, follow the same application procedure while using a bulk gun, the bulk gun can be filled using a follower plate.


Vetoflex PS787 should be removed from tools, equipment and mixers with Vetonit Solvent XX400 immediately after use. Hardened material can only be removed mechanically.

Surface Preparation

Joint Preparation

Clean all joint surfaces and remove any dust, unsound material, plaster, oil, paint, grease, corrosion deposits or algae. Roughen the surfaces, remove any laitence and expose aggregate by light scabbling or grit-blasting. Oil and grease deposits should be removed by steam cleaning, detergent scrubbing or the use of a proprietary degreaser. Any expansion joint filler must be checked to ensure it is tightly packed and no gaps or voids exist at the base of the sealing slot before positioning a bond breaker. The use of a bond breaker is not required in expansion joints containing cellular polyethylene joint filler, backing rod (Vetoflex PBR). For construction or contraction joints a bond breaker tape or back-up strip must be used. Where a particularly neat finish is required, mask the face edges of the joint before sealing and remove immediately after tooling is completed.


Vetoflex PS787 use should follow standard concrete joints practices, sealants need  either backing rod or joint breaker tapes to prohibit 3 point adhesion and allow for movement freedom in desired design. Saveto recommends the use of ACI 224.3-95 (re-approved 2013) for joint design.
