If any of these problems sound like your project then we have the solution for you.

For more information on the type of projects, product breakdowns and testimonials we have received over the years for the entire range.

We would love to help you with your next project so get in touch with Mastermix before deciding on the right concrete coating or concrete repair product. We can help you save time and money by working with you to understand your requirements first. Get the job done right the first time and it will last a long time.

THE RANGE

Mastermix Armor is a high grade product which is hydrophobic with high adhesion characteristics which forms an extremely effective waterproof and acid resistant barrier. It is ideal as a repair solution for masonry and cementitious based substrates which have been damaged in marine or high acidity environments.
In fact, 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.

Rapid Repair is a safe and cost effective alternative to epoxy solutions which are dangerous to use and can cause long term health effects to the applicator:

Infiltration barrier for manholes and tunnels

Commonly used in conjunction with Armor (as a cavity filler)

Reservoir and bridge repairs

Sealing of pipe penetrations in manholes, tanks and reservoirs

Swimming Pools

Canal Refurbishment

Independent laboratory tests carried out in accordance with NZ3112 and is designed to conform to NZ Standards 4210:2001 show that compressive strengths will be achieved as follows:

2 hours – 20.0MPa

24 hours –36.0MPa

28 days – 45.0MPa

Further set time is 17 minutes from mixing.

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.
