UltraPLUS Waterproofing Agent

CretePro® UltraPLUS Waterproofing Agent is a modified silicate solution that provides long-term waterproofing and durability benefits to concrete. It penetrates into concrete and reacts with free calcium and water to form a calcium silicate gel complex in cracks, pores and capillaries. This gel creates a sub-surface barrier against the ingress of water and contaminants such as chloride ions.

CretePro UltraPLUS Waterproofing Agent will seal stable cracks up to 5/64” (2.0 mm) in width and will seal future, non-structural cracks, up to 1/64” (0.4 mm). In the matrix, the product remains reactive when in contact with water, to provide autogenous healing properties to future hairline cracks that increase in size.

Testing

The NSF/ANSI 61 is a set of national standards that relates to water treatment and establishes stringent requirements for all equipment and
products that come in contact with either potable (drinking) water or products that support the production of potable water.
CretePro UltraPLUS Waterproofing Agent has been UL Certified
NSF/ANSI 61.

Application

Basic Requirements
CretePro UltraPLUS Waterproofing Agent must be applied to a clean, dry, dust-free concrete surface, at least 28 days old. If the surface is not clean, then the use of one of the following Alchemco Clean & Repair (ACR) products, or a shot blast system, is suggested for prepping the surface for warrantied applications. Chemical cleaning may require multiple applications and the use of different products to achieve complete cleaning. Certain types of cleaning equipment may improve performance and speed of application when applying chemical cleaners, contact the Technical Department for a list of approved equipment and cleaning methods.

• ACR Concrete & Masonry Cleaner • ACR Emulsifying Cleaner
• ACR Concrete & Masonry Etch • ACR Paint & Stain Remover
• ACR Rust Converter & Inhibitor

Contact the Technical Department for help and directions for which cleaning product will provide the best result for a clean surface.
Where segregation or voids are apparent, chip out and treat with ACR Concrete Patch & Repair. Once repaired, allow at least 24 hours for patches to dry and cure. If works needs to be completed faster, then use ACR HP Concrete Repair.
Do not apply where ambient temperatures are below +39°F (+4°C) or above +95°F (+35°C). Do not apply within 24 hours of the surface being wet.

Application Rates

Normal: 1 gallon per 200 square feet (1 liter to 5 square meters) on average. Can vary depending on substrate absorption, which varies depending on the age of concrete and original density.

Application Method

1. Locate all cracks and flood with solution, first ensuring they are filled with product.
2. Apply the solution to the remaining area at a rate of between 160-240 square feet per gallon (4-6 square meters per liter).
3. First watering – When surface becomes touch dry – (usually 2-6 hours depending on wind conditions and ambient temperature) flood spray the treated areas with water. If product is still wet after 6 hours, begin first watering.
4. On Day 2 – 24 hours later apply CretePro Ultra Activator.
5. On Day 3 – 24 hours later water again.
6. After the third watering, block drains and pond area for a minimum of 12 hours to verify the waterproof seal.
