PLASTISEAL®
MMA Concrete Crack Sealer
A low-viscosity, deep-penetrating MMA crack repair and sealing resin for concrete structures, designed to fill and stabilise hairline to 3 mm cracks while preventing water ingress and extending service life.
PlastiSeal& MMA Concrete Crack Sealer is a 100%-solids, two-component, elasticised methyl methacrylate (MMA) resin formulated for the repair, sealing and consolidation of cracks in concrete substrates. Its very low viscosity and low surface tension provide excellent wetting and capillary penetration, allowing the resin to flow deeply into fine and hairline cracks through to cracks up to ±3 mm.
Features & Benefits
- Deep-Penetrating MMA Resin – Capillary action enables penetration into hairline cracks
- Repairs Hairline to 3 mm Cracks – Suitable for structural and surface crack sealing
- Low Viscosity & Excellent Wetting – Flows easily into tight crack networks
- 100%-Solids, High-Performance System – Minimal shrinkage on cure
- Elasticised Formulation – Provides movement tolerance and crack bridging
- Moisture-Ingress Protection – Helps prevent corrosion and structural deterioration
- Fast Curing MMA Technology – Enables rapid return to service (where conditions allow)
- VOC Value ⟨ 70 g/L – Tested in accordance with ASTM D2369-10 Method E
Intended Uses
PlastiSeal MMA Concrete Crack Sealer is designed for the repair, sealing and reinforcement of cracks in concrete, including:
- Hairline and fine cracks
- Shrinkage and settlement cracks
- Cracks in slabs, decks, floors and walkways
- Cracked beams, columns and precast elements
- Crack stabilisation prior to coating or overlay systems
Suitable for use in:
- Industrial and commercial floors
- Parking structures and ramps
- Warehouses and loading areas
- Civil and infrastructure concrete
- Refurbishment and maintenance projects
The resin penetrates deeply into the crack network, bonding and sealing the concrete substrate from within.
