Overview / Purpose
Lastek 33 Liquid Crack Filler is a high-performance, one-component, pourable crack sealer designed to protect and extend the life of asphalt and concrete surfaces. This black, rubberized asphalt emulsion filler is ideal for cracks up to ½” wide, providing a durable, water-resistant barrier that prepares surfaces for pavement sealers or additional coatings.
Used widely by contractors, municipalities, and maintenance crews, Lastek 33 is essential for professional crack repair, preventing water intrusion, and minimizing further surface deterioration. Its easy pourable design allows crews to quickly address problem areas without complicated equipment or excessive labor.
Contractor-Focused Performance
The formulation of Lastek 33 dries to a black, rubber-hard consistency, providing long-lasting crack protection that resists cracking, shrinking, and water penetration. It is engineered to maintain flexibility in changing temperatures while creating a smooth, professional-looking finish.
Contractors benefit from:
Rapid application with minimal preparation
Compatibility with both asphalt and concrete surfaces
A reliable base for follow-up sealcoat applications
Resistance to cracking or surface movement
Application & Use
Lastek 33 is designed for simple, effective crack repair:
Surface Preparation: Clean cracks thoroughly to remove dust, dirt, debris, and loose material.
Filling: Pour Lastek 33 directly into the crack. For cracks deeper than ½”, partially fill with sand or backer rod before sealing.
Finishing: Squeegee off excess material to create a flush, even surface. Broadcast dry sand for additional traction if needed.
Curing: Allow the crack filler to cure before opening to traffic or applying a pavement sealer.
Coverage is approximately 1 gallon per 200–225 linear feet of ¼” x ¼” cracks, making the 5-gallon pail ideal for medium-sized maintenance projects or multiple smaller repair jobs.
Important Application Notes:
Do not apply below 50°F.
Avoid application when rain is imminent.
Limit use to cracks no wider than ½”.
Durability & Contractor Use
Lastek 33 is formulated for professional use, providing years of protection on high-traffic surfaces. Its rubberized emulsion maintains flexibility, resisting cracking in temperature fluctuations and surface movement, which ensures a longer-lasting repair compared to traditional fillers.
