SealSource AquaSeal - Harden

​

AquaSeal-Harden is a clear, water-based, reacting with calcium hydroxide in Portland concrete forming stable silica structures which harden, densify and retain moisture while concrete is curing as required by ASTM C309. AquaSeal-Harden is an environmentally friendly compound that contains no solvents and has a VOC content that is compliant in all areas of the United States, Australia and EU. A
single component material that creates a stronger, more abrasion resistant surface that will stand up to commercial and industrial floors that are looking for long---term protection against moisture, dirt, abuse, and heavy wear.

 

USES
AquaSeal-Harden’s unique single component sodium silicate formulation is applied to concrete slabs whether newly poured or older. AquaSeal-Harden will penetrate and react with the free lime to enhance both the curing and hardening characteristics. AquaSeal-Harden works well on mechanically troweled or ground/polished concrete surfaces.

​

ADVANTAGES

 

• Unique Technology – allows deeper penetration and a more complete chemical reaction for maximum sealing/ hardening/densification. AquaSeal-Hard densifies the concrete, forming a barrier to outward migration of moisture, reduces shrinkage and crackings.

 

• Ease of Application – Easy application, and material is a single component and ready to use.

 

• Durable – one-time installation provides long lasting protection.

 

• Enhanced Performance – Minimizes shrinkage, dusting and cracking while also improving resistance to chemicals, oil, salts and abrasion during construction.

​

KEY BENEFITS

 

• Provides permanent sheen to concrete surface.

• Abrasion resistance.

• Easy auto-scrub final clean-up

• Contributes to LEED EQ credit 4.2

PACKAGING

• 275 Gallon Totes

• 55 Gallon Drums (drum containers filled by weight, volume is closely approximate)

MIXING
AquaSeal-Harden is a single component product. Prior to use shake container or stir for one to two minutes. AquaSeal-Harden does not need to be diluted.

 

APPLICATION METHODS/COVERAGE RATES

 

AquaSeal-Harden is applied at 250-400 sq-ft per gallon. A broomed surface will yield around 250 sq-ft per gallon (6m2/L). A tightly trowled surface will yield around 400 sq/ft per gallon (10m2/L).
Apply after all surface water is gone and after any joints are to be cut. Remove all dust and debris prior to application. Apply evenly without puddles using a pump-up sprayer, roller or brush. It is important to not over apply. Continuously pushing material with a broom to avoid puddles. Wash thoroughly when material starts to dry.

 

DRYING TIME
Dries in 1-3 hours and is ready for traffic as soon as the surface is dry.

 

SHELF LIFE
AquaSeal-Harden may be stored for up to five years in unopened, factory-sealed container under normal storage conditions of 55o F - 95o F.
