Features & Details

Material & Composition

The sealant is a high-quality polyurethane resin which provides flexibility, adhesion and durability. Suitable for long-wear in outdoor applications, polyurethane is UV light, chemical, and temperature-resistant.

Quick-Drying & Waterproof

Particularly, its quick-drying formula is one of the highlights. Unlike standard concrete fillers, this sealant cures quickly, creating a waterproof barrier that will resist water entering cracks. This prevents any additional erosion and shields your concrete from seasonal damage.

Weather-Resistant

It is an all-season sealant. Whether it be sweltering summer heat, below-zero winter temperatures, or torrential downpour, the repair will hold up. This sealant has exceptional UV and weather-proofing features that prevent the sealant from peeling, cracking, or fading over time.

Strong Adhesion & Flexibility

Concrete reacts to temperature, where it will expand and contract. This sealant is flexible after curing, unlike rigid fillers, providing the capability to move with the concrete, thus minimizing the risk of cracking again in heavily trafficked areas.

Ease of Use

This sealant is easy enough for even a novice user to utilize it properly. Just clean the crack, cut the nozzle, and squeeze the sealant into the crack. Use a spatula/curving tool to smooth it out if it looks a bit rough. It doesn’t require anything special tool tool-wise or professional.

Personal Experience 

Although there are many different types of sealant for cracks, practical experts in concrete and repair argue that the best concrete crack sealant to use retains its elasticity and remains firmly adhered to the concrete surfaces whilst allowing very minute movements that causes the crack. In contrast to cement-based fillers, which cure rigid and becomes more susceptible to cracking upon a temperature change (cold to hot), polyurethane maintains its flexibility.

This product is inexpensive and would be ideal for homeowners in lieu of a professional. Similarly, its vapour barrier allows concrete solutions to remain protected from prolonged water exposure, preventing erosion or degradation of the integrity of the structure.

Tip: Apply sealant to the concrete if you want it to last TIP: Combine with frequent wash every few months and crack inspection.
