Temperature capability

A wider maintenance window across the year.

Boydur M12 may be applied from −10°C to +40°C. Temperature changes working and curing behaviour; material, substrate and ambient conditions must all be considered before mixing.

Cold conditionsWorking and curing times change; plan the intervention using current TDS guidance.

Warm conditionsReaction accelerates; organise labour, tools and placement before components are combined.

System suitability

Three core application roles. One rapid MMA platform.

Suitability depends on substrate strength, preparation, geometry, exposure and required reopening time. Technical review is recommended for critical work.

01 / REPAIR

Surface and edge repair

For suitable potholes, broken edges, steps, ramps, joint shoulders and local damage requiring fast return to use.

02 / TOPPING

Heavy-duty floor topping

For minimum 5 mm topping where rapid curing, mechanical performance and operational availability are priorities.

03 / ANCHORING

Time-sensitive anchoring

For suitable posts, guardrails, machinery bases and fixtures, subject to geometry and engineering requirements.

SUBSTRATE

Concrete and asphalt

For compatible, structurally sound and correctly prepared substrates. Project conditions must be checked before use.

EXPOSURE

Industrial environments

Developed for heavily used facilities exposed to traffic, abrasion, weather and routine operational stress.

SECTORS

Critical infrastructure

Airports, ports, factories, logistics centres, bridges, roads, parking structures and service facilities.

Application protocol

Correct preparation determines the quality of the repair.

Inspect and define

Confirm substrate condition, repair geometry, contamination, moisture, traffic, exposure and required reopening time.

Prepare the substrate

Remove weak material, laitance, dust, oil and contaminants. Create clean, stable edges and a sound mechanical key using an appropriate preparation method.

Prime as specified

Use the compatible Boydur MMA primer when required. Observe the current product instructions, coverage and overcoating condition.

Combine the premeasured set

Condition and mix the supplied components exactly as stated in the current TDS and on the packaging. Do not improvise component ratios or divide sets without an approved method.

Place, compact and finish

Apply within the available working time, compact thoroughly and finish to the required profile and minimum specified thickness.

Protect and reopen

Protect the area from traffic and contamination until adequately cured. Confirm reopening according to temperature, site conditions and the current technical guidance.

Before specification

Four controls that should never be skipped.

01 / SUBSTRATEStructural condition and preparationThe repair is only as reliable as the substrate beneath it. Weak, moving or contaminated material must be addressed before application.

02 / ENVIRONMENTTemperature, moisture and ventilationCheck material, substrate and ambient conditions. Plan ventilation and safe handling in accordance with the SDS.

03 / GEOMETRYDepth, edge detail and quantityConfirm repair dimensions, minimum thickness and material demand before mixing the short-working-time system.

04 / OPERATIONTraffic and chemical exposureVehicle type, load, turning forces, cleaning regime and chemical contact all influence the final specification.

Technical FAQ

The most important questions before site work.

How quickly is Boydur M12 traffic-ready?

At 20°C, Boydur M12 is typically traffic-ready in approximately 60 minutes. Actual working and curing times vary with material, substrate and ambient temperature and with site conditions.

What is the application temperature range?

The stated application range is −10°C to +40°C. Temperature directly affects reaction speed, working time and curing, so the current TDS must be followed.

What is the minimum topping thickness?

Boydur M12 is intended for floor topping from a minimum thickness of 5 mm. Repair and anchoring geometries require project-specific evaluation.

What are the principal mechanical values?

Typical values include compressive strength of approximately 34 N/mm², flexural strength of approximately 25 N/mm², E-Modulus of approximately 4,350 N/mm² and Shore D hardness of 75–80.

How is Boydur M12 supplied?

It is supplied as an 18 kg two-component set configured as 3 kg plus 15 kg. Mix and use the premeasured components according to the current TDS and packaging instructions.

What is the shelf life?

The stated shelf life is 6 months in original unopened packaging under the prescribed storage conditions. Always check the product label, batch date and current TDS.

Can the system be divided into smaller batches?

Do not divide or alter component ratios unless an approved weighing and mixing procedure has been provided. Incorrect ratios can compromise curing and performance.

Project-specific support

Send the site conditions—not only the square metres.

For a meaningful review, include substrate, repair dimensions, temperature, traffic, exposure and required reopening time.
