Ardex K 15 Calculator

Ardex K-15 is a high-performance adhesive designed for construction applications. This calculator helps you determine the correct amount of Ardex K-15 needed for your project by calculating coverage, material requirements, and estimated cost.

What is Ardex K-15?

Ardex K-15 is a two-component epoxy adhesive system that provides excellent bonding strength and durability. It's commonly used in construction for applications such as:

Bonding concrete to concrete
Repairing concrete structures
Joining metal to concrete
Waterproofing applications

The "K-15" designation refers to the product's specific formulation and performance characteristics. It's designed to provide a strong bond while remaining flexible enough to accommodate movement in concrete structures.

How to Use the Calculator

Using the Ardex K-15 calculator is simple:

Enter the area to be covered in square feet
Select the application type (concrete-to-concrete, metal-to-concrete, etc.)
Enter the price per gallon of Ardex K-15
Click "Calculate" to see the results

The calculator will provide you with:

Amount of adhesive needed in gallons
Estimated cost of the adhesive
A chart showing the material requirements

Formula and Assumptions

The calculator uses the following formula to determine the amount of Ardex K-15 needed:

Amount (gallons) = (Area / Coverage Factor) * 1.1
Cost = Amount × Price per gallon

The coverage factor varies based on the application type:

Concrete-to-concrete: 200 sq ft per gallon
Metal-to-concrete: 150 sq ft per gallon
Waterproofing: 180 sq ft per gallon

The 1.1 multiplier accounts for waste and application inefficiencies.

Note: These are general guidelines. Actual coverage may vary based on specific conditions and manufacturer recommendations.

Example Calculation

Let's say you need to bond 500 square feet of concrete to concrete using Ardex K-15 at $40 per gallon:

Area: 500 sq ft
Application: Concrete-to-concrete (200 sq ft/gallon)
Price: $40/gallon

Calculation:

Amount = (500 / 200) × 1.1 = 2.75 gallons
Cost = 2.75 × $40 = $110

You would need 2.75 gallons of Ardex K-15, costing approximately $110.

Frequently Asked Questions

What is the difference between Ardex K-15 and other epoxy adhesives?

Ardex K-15 is specifically formulated for construction applications and provides excellent bonding strength while remaining flexible. It's designed to accommodate movement in concrete structures better than some other epoxy adhesives.

How long does Ardex K-15 take to cure?

Ardex K-15 typically cures within 24 hours, with full bond strength achieved in about 7 days. The exact curing time may vary based on environmental conditions.

Can I use Ardex K-15 outdoors?

Yes, Ardex K-15 is designed for both indoor and outdoor construction applications. However, proper surface preparation and protection from moisture are important for outdoor use.
