AIM DP V Solvent Semi Mastic Damp Proofing is a cold-applied, solvent-based asphalt damp proofing and vapor-retarding coating. AIM Solvent Semi Mastic is reinforced with short fibers for application by brush or spray. AIM DP V Solvent Semi Mastic is ready to use for damp proofing the exterior surface of below-grade foundations and walls and other dry concrete, concrete block or masonry surfaces.

Applicable Specification: ASTM D 4479, Type 1

SURFACE MUST BE COMPLETELY DRY AND FULLY CURED PRIOR TO APPLICATION

Do not apply AIM Solvent Semi Mastic when temperatures below 35° F (2° C) are anticipated. Do not apply in rain or when rain is threatening. Surface to be coated should be free of oil, grease, dirt, laitance and loose material. Apply AIM Solvent Semi Mastic by brush, roller or spray with the proper equipment. Consult the spray equipment manufacturer for more information. If primer is required, use AIM Solvent Spray Mastic. AIM Solvent Semi-Mastic should be thoroughly stirred in the container prior to application.

FOR DENSE EXTERIOR BELOW-GRADE SURFACES

Apply AIM Solvent Semi Mastic by brush or roller or spray with the proper equipment. Consult the spray equipment manufacturer for more information. For dense surfaces and exterior surfaces below grade: Fill in all crevices and grooves, making sure 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. Backfill should be done within 24 – 48 hours after application. Do not wait longer than seven days maximum before backfilling. Be careful not to damage or rupture the film or displace coating. Some situations may require protection board.

FOR POROUS EXTERIOR BELOW-GRADE SURFACES: Three Options are available.

1. For Membrane System: For severe conditions or for added protection, apply one coat of AIM Solvent Semi Mastic Damp Proofing on porous surfaces (such as block), according to Dense Exterior Below-Grade Surfaces Application, listed above. Within four hours, apply a glass fabric membrane cloth over all coating surfaces. Overlap all edges by 3″ minimum. Press firmly into place without wrinkles. Application of the second coat of AIM Solvent Semi Mastic Damp Proofing should be with-in 24 hours.
2. For Two-Coat System: Apply AIM Solvent Spray Mastic Damp Proofing as a prime coat. Allow coat to dry tacky to touch, then apply AIM Solvent Semi Mastic in one coat, according to Dense Exterior Below-Grade Surfaces Application, listed above. Backfill should be done within 24 to 48 hours after application. Do not longer than seven days maximum before backing. Be careful not to damage or rupture the film or displace coating.Some situations may require protection board.
3. For Parge Coat System: Before application of AIM Solvent Semi Mastic Damp Proofing apply a heavy parge coat of cement mortar for surface preparation. The coat should cover the bottom of the footing to grade level, forming a cove at the junction of the wall and footing. Once the parge coat cures, apply two spray coats of AIM Solvent Semi Mastic Damp Proofing according to Dense Exterior Below-Grade Surfaces Application, listed above. Backfill should be done within 24 to 48 hours after application. Do not wait longer than seven days maximum before backfilling. Be careful not to damage or rupture the film or displace coating. Some situations may require protection board

FOR INTERIOR ABOVE-GRADE SURFACES-VAPOR RETARDER

AIM Solvent Semi Mastic Damp Proofing can be used individually or in combination with AIM Solvent Spray-Mastic or AIM Solvent Trowel Mastic for damp-proofing the exterior face of interior walls in cavity wall construction.

Clean up with mineral spirits or waterless hand cleaner. Use care when handling solvents.
