When use MaxRite 700 vs MaxRest?

MaxRite 700 is the premium repair mortar for aggressive environments - marine, bridges, harbours, dams, chloride-exposed structures. MaxRest is the standard repair mortar for general structural work. Both are R4-rated.

What's the strength rating?

MaxRite 700 achieves 43.3 MPa compressive at 7 days, 56.4 MPa at 28 days. Flexural 10.3 MPa at 28 days. Bond strength exceeds 2.0 MPa. Includes silica fume, polymer modifiers, and corrosion inhibitors.

Application thickness and method?

Apply 5-50mm per layer (wider range than standard MaxRest). Trowel or wet-spray application. Pot life 60 minutes, initial set 75 min, final set 120 min - much longer working time than MaxRest's 15-min pot life.

Suitable for marine and chloride environments?

Yes - this is its primary application. Carbonation resistance ≤4.0mm, capillary absorption ≤0.5, chloride ≤0.05%. The corrosion inhibitor protects embedded steel beyond the patch boundary.

Standards compliance?

EN 1504-3 R4 Structural (Type PCC). Principles 3, 4, and 7 (CR, SS, RP). Also EN 1504-7 Declaration of Performance for rebar protection. Fire reaction Class A1.

How to Use

Brush on a bonding slurry of 5 parts powder to 1 part water, then trowel or wet spray the mortar in layers of 5mm to 50mmRemove all damaged and loose concrete until sound concrete is reached and sawcut the edges perpendicular to the surface to a minimum depth of 5mm
Expose all corroded reinforcement, removing concrete until the edges of the bars are clear of rust and there is room to surround each bar with at least 1cm of MAXRITE 700
Eliminate rust by wire brush, needle gun, sand or shot blasting
For additional protection apply the oxide converter and protector MAXREST PASSIVE to the reinforcement
Clean the surface free of paints, coatings, efflorescence, loose particles, grease, oils, curing agents, form release agents, dust, gypsum plasters and organic growth using sand blasting or high pressure water
Dampen the whole repair area thoroughly with clean water, avoid puddles, let excess water drain and start once the surface acquires a matte appearance
Mix 3.75 to 4.25 litres of clean water per 25kg bag, adding the powder slowly to the water
Mix with a slow speed electric drill at 400-600 rpm and a disc mixer for 2-3 minutes to a smooth, lump-free mortar of dry consistency
Rest the mix for 3 to 5 minutes to fully wet out the powder, then remix briefly before applying
Brush a bonding slurry of 5 parts MAXRITE 700 to 1 part water onto the prepared surface and the reinforcement bars, working it into all micro-pores and voids
Start placing the mortar when the slurry begins to lose brightness but is still fresh, and re-slurry if it dries up
Apply layers between 5mm and 50mm thick, pressing the mortar with the trowel to prevent trapping air
For spray application, saturate the surface without puddling, wait until it begins to lose brightness, then project the mortar in 5mm to 50mm layers with the pressure adjusted to minimise rebound
Scratch the surface of each previous layer with a trowel before the next lift and apply successive layers only when the previous one is completely set
Finish with a sponge, wood or plastic float or trowel, shaping the last layer before final set, and do not overwork the mortar
Protect the repair from extreme heat and direct sunlight and keep it moist for at least 24 hours by misting with water, using polyethylene sheeting or damp burlaps, or applying MAXCURE
Overcoat where specified with a cement-based coating such as MAXSEAL or MAXSEAL FLEX, or an acrylic coating such as MAXSHEEN or MAXSHEEN ELASTIC
Clean all mixing and application tools with water immediately after use

Technical overview

MAXRITE 700 is a one-component, cement-based, silica fume-enhanced, polymer-modified and fibre-reinforced restoration mortar with corrosion inhibitors, designed for high performance structural concrete repair in aggressive environments and to give the steel reinforcement additional protection. Its long open time and thixotropy allow new and old concrete to be repaired without formwork, by hand with a trowel or by wet spraying, in layers of 5mm to 50mm. It is CE marked under EN 1504-3 as Type PCC, Class R4, with declared values of 56.4 MPa compressive strength at 28 days, 2.1 MPa bond to concrete under EN 1542 and Euroclass A1 reaction to fire. Those are CE declared performance values, not an Australian accredited test result, and no NATA or CodeMark certificate is published for this product.

Key applications

Repair of concrete affected by corrosion of reinforcements in marine environment, bridges, harbours and dams
Repair of general structural concrete on vertical or overhead surfaces, without form works
Repair of lines and shapes in pre-fabricated concrete elements damaged by mechanical impacts, corrosion of reinforcements and freeze/thaw cycles
Repair of pillars, lintels, raincaps and architectural concrete exposed permanently to extreme weather
Repair of concrete affected by repeated loads
Structural strengthening of concrete elements by adding mortar
Restoration of passivity for rebars, increasing cover and replacing contaminated concrete
Maintenance of industrial areas damaged by aggressive environment, acid rain and atmospheric pollution
Patching of cold joints and making of concave corners prior to waterproofing jobs in reservoirs, swimming-pools and basements

Surface suitability

Concrete (structurally sound and firm, without cement laitance, damaged and loose concrete removed, edges sawcut perpendicular to a minimum depth of 5mm)
Concrete with corroded reinforcement (bars fully exposed and de-rusted, surrounded by a minimum 1cm of MAXRITE 700)
Concrete dampened thoroughly with clean water, excess drained, applied once the surface acquires a matte appearance

Do not apply on substrates that are vitrified or enamelled, or treated with water repellent agents, and do not apply on bituminous materials, metals, wood, plasters or paints. Do not apply over weak substrates. Do not add cements, additives, aggregates or other compounds, do not use leftovers from previous mixes, and never add more water to restore workability - remix instead. Observe the recommended consumptions and thickness per layer of 5mm to 50mm. Do not apply in rain or when rain, contact with water, condensation, dampness or dew is expected within the first 24 hours after application. Do not apply with substrate or ambient temperature at or below 5C, or when temperatures are expected to fall below 5C within 24 hours, and do not apply to frozen or frost-covered surfaces. Do not use in contact with very soft water, acid water or carbonic water; where sulphates are present in groundwater, seawater or wastewater use the MAXRITE 700 ANTISULFAT sulphate-resisting version. MAXRITE 700 is an abrasive composition - avoid direct contact with skin and eyes and breathing dust, and use rubber gloves and safety goggles when handling, mixing and applying it.
