EverKrete 102

For fast-turnaround concrete repairs, cold-weather priming, and slip-resistant protective toppings, EverKrete 102 is a flexible, micro-fibre reinforced thermoset vinyl polymer binder. Mixed with kiln-dried sand and aggregate, it forms a high-strength concrete repair mortar, or can be saturated with sand to create a hard-wearing surface overlay.

What it does

EverKrete 102 functions as the chemical binder in the EverKrete concrete repair system, curing rapidly to allow full traffic access within 90 minutes. The thermoset vinyl polymer chemistry provides low viscosity to easily wet out aggregate, and once cured, it does not re-emulsify in wet or outdoor environments. It also serves as a cold-weather concrete primer on cold substrates down to -18°C, ensuring adhesion where conventional primers fail to cure.

Numbers that matter

• 45 to 90 minutes cure time: Allows full traffic return quickly after installation.
• -18°C to +35°C application range: Wide working window, requiring EverKrete Accelerator for temperatures below 10°C.
• 13-minute pot life (unfilled at 25°C): Quick working window that extends to approximately 20 minutes when mixed with 80% aggregate.
• 99% solids by weight: High-build resin formulation with minimal volume loss, exhibiting 1.1% linear shrinkage unfilled and 0% shrinkage when filled.
• 500 to 700 mPa.s viscosity: Low-viscosity sticky liquid that flows easily to saturate dry aggregates and penetrate concrete capillaries.

Where to use it

EverKrete 102 is suitable for internal and external applications on the following prepared substrates:

• Concrete cured for a minimum of 28 days
• 3:1 sand cement screed or C-Bed
• Masonry and render cured for at least 4 days
• Pre-cast concrete once all release agents are completely removed or dissipated
• Brickwork, Hebel, and concrete blocks

Installation limits

To prevent adhesion failure and ensure a correct chemical cure, the following application parameters must be maintained:

• Moisture and weather: Do not apply on damp, wet, or contaminated substrates, or if rain is imminent.
• Substrate temperature limits: Surface temperature must be between 10°C and +35°C if applying without EverKrete Accelerator. With EverKrete Accelerator, the acceptable surface temperature range is -18°C to +35°C. Do not apply if the surface temperature is below -18°C or above +35°C.
• Catalysation sequence: Always pre-mix EverKrete 102 to disperse any settled material, and thoroughly mix in the EverKrete Catalyst before adding any sand, aggregate, or EverKrete LVF (Low Volume Filler).
• Mixing ratio: Use 2 parts Catalyst to 100 parts EverKrete 102 by weight. This can be increased up to 3 parts Catalyst to 100 parts resin for a faster cure.
• Chemical caution: Do not add EverKrete Catalyst and EverKrete Accelerator to the mix at the same time. Add and mix the catalyst first, then add the accelerator.
• Aggregates: Use only kiln-dried sand. For general repairs, use 20-40 mesh (coarse) sand; for fine feather-edging, use 40-60 mesh (fine) sand.
• Clean-up: Clean tools and spills with Acetone while the resin is still wet. Cured material can only be removed mechanically. Do not use coloured rags for clean-up to avoid dye bleeding into the resin.

System components

Depending on the repair requirements, EverKrete 102 is used in conjunction with:

• EverKrete Catalyst: Required powder initiator (included with the resin).
• EverKrete Primer (EverKrete 2P): Substrate primer. EverKrete 102 mortar must be applied on the same day as the primer, while the primer is dry to a tacky state.
• EverKrete Accelerator: Additive to speed up curing or enable application on cold substrates below 10°C.
• EverKrete LVF (Low Volume Filler): For adjusting mortar consistency and achieving a greyer finish.
