Mastermix Armor – Acid Resistant & Waterproof Concrete Coating.

'Armor' is a high grade product which is hydrophobic with high adhesion characteristics which forms an extremely effective waterproof and acid resistant barrier, and can withstand compressive loads of up to 14.7MPa
Mastermix Armor – Acid Resistant & Waterproof Concrete Coating.
Product Introduction and Description

Mastermix Armor has been designed to repair masonry and cementitious based substrates which have been damaged in marine or high acidity environments. This includes the difficult conditions found in Wastewater Plants where replacement is not an option.

A single 10mm coat of Armor will provide a highly effective acid resistant and waterproof barrier which can withstand compressive loads of up to 14.7MPa making for a durable and hard service which will extend the life of your project.

Independent tests from respected international laboratories such as AMS Laboratories are in the process of being revamped to better understand the performance limits of this product. Armor is redefining the Industry Standard for its product category.

Further as it is developed with marine environments in mind Mastermix has commissioned independent tests which have verified the water potability of the solution. This includes meeting AUS Standards/NZ Standards 4020-2005 for Taste, Turbidity, Aquatic Microorganism growth, Cytotoxic activity, Mutagenic activity and Extraction of metals.

Product Performance

As part of our commitment to developing the best products for your projects, Mastermix has maintained a 20 year history of rigorous testing via internationally recognised laboratories. We pay top dollar to put our products to the test so you don’t have to.

IANZ Laboratory Results: Armor has been independently tested by AMS Labs under the following test condition EN 1348, AUS Standards 134 and NZ Standards 3112.

Adhesion >1 Mpa Compressive Strength 14.7MPa
Flexural Strength 6MPa Residual Strength 11.26MPa
Shrinkage 0.005% Acid Resistance Very high when immersed at pH0

Laboratory partners such as AMS have commited to redeveloping the testing standards for refurbishment products to better understand the performance limits of Armor and the expected Industry Standard for competing products in this category.

Armor has also been tested and conforms to AUS Standards/NZ Standards 4020-2005, these tests include Taste, Turbidity, Aquatic Microorganism growth, Cytotoxic activity, Mutagenic activity and Extraction of metals.

PackagingArmor comes packaged in 30kg weatherproof bags with a shelf life of 3 months when kept in cool, dry conditions.
Instructions

Prepare the surface of the substrate to ensure it is clean of:Grease, loose and weak materials, other foreign matter.
Recommend high pressure washing at 700bar (10,000psi) with the excess water being removed with compressed air.

Mix 15kg of Mastermix Armor with 3 litres of potable water, starting with 1 litre and adding water until an homogeneous mix is achieved. Mechanical mixing is preferred.

Apply the mixture using a trowel until the optimum thickness of between 7mm to 15mm is achieved.

Armor should be applied in temperatures between 7°C and 25°C applies to both substrate and ambient) and will remain workable up to 20 minutes at 20°C. Temperature, humidity and water content will affect the workability time. Armor should not be applied in temperatures below 7°C.

Curing time to allow water flow is 2¾ hours, subject to water flow rates. Curing time to compressive hardness is 12 hours. Both times are based on an ambient temperature of 20°C. Temperature, humidity and water content will affect these times.

Do not feather joints.

Coverage & Performance

Each 30kg bag will cover approximately 1.60m2 at a thickness of 10mm.

A single 10mm coat of ‘Armor’ will provide a highly effective acid resistant and waterproof barrier providing a hard and durable surface finish when applied to masonry and cementitious based substrates. 

Warranty

A warranty maybe offered, subject to strict conditions, and each project will be assessed on its own merits. However, as an  indication of the longevity of the product, accelerated tests have shown that in a sewer environment with pH levels of pH3.5 the life expectancy would be better that 50years.

Often times we EXCEED the required project warranty period by up to 43 years!
