AQURON 2000 ultimate internal curing, hardening and anti-dusting, and moisture control in one application.

 Where can i use AQURON 2000 ULTIMATE MOISTURE CONTROL?
AQURON 2000 can be applied to new and old concrete to control elevated moisture levels. AQURON 2000 is strictly only available as a SUPPLY & APPLY. AQURON 2000 SUPPLY & APPLY is strictly in accordance with AQURON CORPORATION specifications, and accommodates varying concrete absorbencies. AQURON 2000 SUPPLY & APPLY means that you get the promised results and a ultimate 15 year warranty by means of a quality controlled installation carried out by experienced applicators. AQURON 2000 SUPPLY & APPLY method eliminates all risks for you and is your assurance of performance over time.

Why is AQURON 2000 ULTIMATE MOISTURE CONTROL unique?
AQURON 2000 is a spray applied non-toxic, colloidal silicate with a unique reactive catalyst that results in the treatment penetrating up to 150mm into concrete. AQURON 2000 is the ultimate choice for internally controlling moisture in concrete beneath coverings & coatings. Once applied to concrete, AQURON 2000 induces a distinct chemical reaction converting the alkalinity and moisture into a permanent hydrogel throughout the concrete transforming all “free moisture”.

How quickly can floorcoverings or coatings be installed after AQURON 2000 ULTIMATE MOISTURE CONTROL application?
Providing AQURON 5 rules & 8 precautions are followed, floor coverings and coatings can be confidently installed 28 days after placing the concrete, or 72 hours after application to existing concrete.

How does AQURON 2000 ULTIMATE MOISTURE CONTROL offer concrete curing assistance?
Once applied to concrete, AQURON 2000 induces a distinct chemical reaction, converting the alkalinity and moisture into a permanent hydrogel throughout the concrete transforming all “free moisture”. AQURON 2000’s hydrogel formation improves concrete curing and effectively reduces shrinkage, risk of cracking, surface crazing, delamination & slab curl. AQURON 2000 also maximises flexural & compressive strengths and provides hardening & anti-dusting without compromising the surface key required for adhesives.

Does concrete have to be diamond grind prior to AQURON 2000 ULTIMATE MOISTURE CONTROL to allow penetration?
If water will penetrate into the concrete surface so will AQURON 2000 ULTIMATE MOISTURE CONTROL. It is NOT a rule that concrete surface’s must be diamond ground prior to AQURON 2000 ULTIMATE MOISTURE CONTROL being applied. It is however a rule, that the concrete surface must be absorbent to water (refer AQURON Bulletin “How to Test for Absorbency”). Any curing compounds, tilts release, membranes, coatings, sealers. Flooring leveling compounds must be removed to expose a natural concrete surface.

Is AQURON 2000 ULTIMATE MOISTURE CONTROL applied before or after floor leveling compounds/screeds?
AQURON 2000 is formulated to be applied to concrete to penetrate into porosity,  react with the calcium hydrates (CSH) and transform "free moisture" into a hydrogel. As flooring leveling compounds and cementitious screeds normally have latex or arcylic components as the "binder", AQURON 2000 hydrogel will appear to soak into these surfaces but will not set up a hydrogel. AQURON 2000 must be applied prior to any floor leveling compounds to control moisture in the concrete substate.

NOTE: AQURON 2000 treated surfaces are compatible with FLC's and screeds refer FAQ below "Is AQURON 2000 ULTIMATE MOISTURE CONTROL compatible with adhesives, floor leveling compounds etc?"

Does concrete have to be diamond grind after AQURON 2000 ULTIMATE MOISTURE CONTROL?

It is NOT a rule that AQURON 2000 treated concrete surface’s must be diamond ground prior to installing further coatings or coverings. It is a rule, that AQURON 2000 treated concrete must be absorbent prior to installing further coatings or coverings (refer AQURON Bulletin “How to Test for Absorbency”). Some burnished finished concrete can typically be so hard that progress sanding alone is not sufficient to produce an adequately absorbent surface, and diamond grinding will be required to achieve the necessary surface profile & absorbency. Under these circumstances diamond grinding preparation is required to create absorbency whether or not AQURON 2000 was applied.

Does AQURON 2000 ULTIMATE MOISTURE CONTROL effect Surface PH?
AQURON 2000 solution in the pail has a high PH level. When applied to concrete, AQURON 2000 penetrates into the concrete porosity and chemically forms a (Calcium Silicate Hydrate) Hydrogel. Calcium Silicate Hydrate is the main binder of concrete. Providing the AQURON 2000 has completely penetrated and the concrete surface has been made absorbent as per AQURON 5 rules & 8 Precautions prior to flooring compounds and adhesives being installed, the surface PH levels will be similar to the untreated concrete.

Will AQURON 2000 ULTIMATE MOISTURE CONTROL remove RH? And will moisture measuring devices record the before and after difference?
AQURON 2000 controls moisture inside the concrete porosity. AQURON 2000 does not remove moisture, therefore AQURON 2000 treated concrete will have measureable Relative Humidity (RH). AQURON 2000 moisture control is guaranteed regardless of measureable RH% in the concrete providing AQURON 5 rules & 8 precautions are followed.

Is AQURON 2000 ULTIMATE MOISTURE CONTROL compatible with adhesives, floor leveling compounds etc?
AQURON 2000 is a colloidal silicate. Once AQURON 2000 has penetrated and reacted with the moisture and alkalinity in the concrete, a Calcium Silicate Hydrate (CSH) is formed in a hydrogel. The main binder of untreated concrete is Calcium Silicate Hydrate (CSH). Therefore any floor preparation, adhesives or coating formulated to be applied to untreated concrete is  compatible with AQURON 2000 treated concrete.
