I am uncertain about the integrity of my structure. What should I do?
It is very easy and cost effective to restore structural integrity. All required information and tips are in the information booklet in the kit and on our website.
Are there any dangerous fumes given off during application?
No
Does the area to be treated need to be dry?
No. In fact it "must" be wet.
Does the concrete need to be clean?
Yes. Mr Crystal must be applied directly to clean concrete. Mr Crystal has a chemical reaction with the concrete thus; the better it is in contact with the concrete – the better the reaction will be.
Does the concrete have to be gouged out?
How does Mr Crystal protect the reinforcement?
In two ways.
- Physically – By protecting the steel from the elements (water, minerals and air)
- Chemically – By reinstating alkalinity into the concrete.
How long will it last?
What are the limitations of the product?
Mr Crystal will generally repair a concrete structure for the retention of liquid to Australian Standard AS3735, provided that;
- The structure has basic structural integrity.
- It is made from concrete (commonly known as Portland Cement)
- It is used according to enclosed directions
Is it guaranteed to work?
Yes. As with all products sold in Australia, it is law (Trade Practices Act 1974), that products be accurately represented and sold as "fit for the intended purpose".
Can Mr Crystal block up my plumbing, or grow into the water?
No. Mr Crystal relies on the chemicals "within" the concrete. Therefore it can only function within the concrete. It cannot leach into water or plumbing.
Is it safe for drinking water?
Yes, it is less toxic than the concrete your tank is made from. It is approved by water authorities in most countries.
Does It Only Work On Concrete
Yes, Mr Crystal utilises the existing concrete as part of its chemistry.
How Do I Apply Mr Crystal?
Mr Crystal comes in a powder form. The material is mixed into a paintable slurry, and then applied with a brush to the cracks (two coats). A strip of material 60mm wide and 6mm thick is required.
How Does It Work
Rather than trying to cover the crack or hole, Mr Crystal actually repairs the concrete by having a chemical reaction with the concrete, which in turn, generates the growth of a non-soluble crystalline formation, which becomes part of the structure itself.
