Sikalastic®-310

Sikalastic®-310 complies with ASTM D 1187, Type 1, and ASTM D 1227, Type 3, Class I

Sikalastic®-310 is a asphalt-based emulsion.

1 year when properly stored

Store in unopened containers in a cool, clean, dry area. Do not allow these materials to freeze in the container; do not store below 35° F (2° C).

Surface should be free of oil, grease, dirt, laitance and loose material. Dry surfaces must be dampened with water and kept damp until application.

1. Apply Sikalastic®-310 by brush, roller or spray with the proper equipment. Consult the spray equipment manufacturer for more information.

Exterior Surfaces Below Grade - Dense Surfaces

1. Apply Sikalastic®-314 in one coat by trowel or apply 615 in two coats by brush, roller or spray. Allow first coat to dry tacky to touch before applying second coat.
2. Fill in all crevices and grooves, making sure the coating is continuous and free from breaks and pinholes. Carry coating over exposed top and outside edge of footing. Spread around all joints, grooves, and slots and into all chases, corners, reveals and soffits. Bring the coating to finished grade.
3. Backfilling: Place backfill at least 24–48 hours after application, but within 7 days. Do not rupture or damage the film or displace the coating or membranes. Some situations may require protection board.

Exterior Surfaces Below Grade - Porous Surfaces
Three alternate techniques are equally effective.

1. Membrane system: Apply one coat of Sikalastic®-314 or two coats of Sikalastic®-315 as described above under Dense Surfaces. Within 4 hours, apply Sikalastic®-995 or glass-fabric membrane cloth over all surfaces of coating, overlapping all edges at least 3" (76 mm). Press firmly into place without wrinkles. Within 24 hours, apply an additional coat of Sikalastic®-314 or Sikalastic®-315. Allow setting and backfilling as described above under Backfilling.
2. Two-coat system: Apply a prime coat of Sikalastic®-310 asphalt emulsion, cut 20% by volume with clean water. Allow prime coat to dry tacky to touch and apply one coat of Sikalastic®-314 as described above under Dense Surfaces. Allow to set and backfill as described above under Backfilling.
3. Parge coat system: Apply a parge coat of cement mortar to the block wall, carrying the parge coat from the bottom of the footings to grade level and forming a cove at the junction of the wall and footing. Allow to cure (typically 7 days). Apply either one trowel coat of Sikalastic®-314 or two brush, roller, or spray coats of Sikalastic®-315 as described above under Dense Surfaces. Allow to set and backfill as described above under Backfilling.

Interior Surfaces Above Grade - Vapor Retarder

1. Sikalastic®-310, Sikalastic®-314, and Sikalastic®-315 may be used individually or in combination for dampproofing the exterior face of interior walls in cavity wall construction.
2. Sikalastic®-314 and Sikalastic®-315 are excellent vapor retarders. Apply in one coat, carrying the coating in and around all joints, grooves and slots, following all reveals and soffits of windows and continuing 12" (305 mm) out on adjoining partitions and soffits. Sikalastic®-310 may also be used. Use one, two, or more coats, as needed, depending on amount of vapor retarding required.
3. Allow to set. If walls are to receive hard wall plaster, use furring strips or metal lath.
4. Sikalastic®-314 and Sikalastic®-315 have been used successfully for bonding polystyrene insulation board to a wide variety of substrates. On-site testing with actual substrate is recommended.

Clean tools and equipment immediately with hot, soapy water. Cured material can be removed with SikaSwell^®-990.
