1. KEFA Coating Presentation to New York City Transit 2 Broadway January 25, 2007 Robbie Wood and Regis Doucette 201.664.5487

2. KEFA Coating We create dry surfaces We improve the indoor climate Micro porous coatings

3. KEFA Pedigree • On the market for over 30 years • Product applied over 400,000,000 sq ft • In over 40 countries • First application 1975 - Still working • Products are based on 3 patents • Developed in co-operation with • Swedish, US, UK Universities

4. What is a KEFA Coating ? • A microporous coating • Water based • Harmless to health • Harmless to environment • It works forever • It works automatically/passively • Not a 1-use like intumescents

5. Some KEFA Benefits • KEFA – Condensation Protection • KEFA – Mold Protection • KEFA – Facade Paint • KEFA – Heat Protection • ALL NATURAL NON-CHEMICAL

6. KEFA Coating x 500

7. Microporous structure providesinteresting properties • Condensation protection • Improves rust protection + detects corrosion • Mold remediation • Insulates • Dries out fresh construction • Improves insulation • Does not attract dust and dirt • Noise damping

8. KEFA Coatings Speed up evaporation

9. KEFA Coating requires a cyclic condensation process with dry periodsbetween condensation periods Dew point

38. Why avoid mold? Mold looks bad and creates smell Mold is an early step in the degradation process Mold can produce mycotoxins Dangerous to your health

39. Conditions for growth of mold and other organisms Presence of spores Average over the year >3 000/sqftair Nutrition = all organic material Construction material, dust, dirt, pollen Free water Condensation, construction water, leakage water Time and temperature

40. Probability of mold growth Cold bridges increase aw dramatically RH=aw 1,0 High probability 0,95 Within 4 weeks 0,90 Too cold Too hot Within 8 weeks 0,85 Possible 0,80 Too dry 0,75 14 32 50 68 86 104 122 140 Temperature °F

44. What Kefa Does Not Do

45. Kefa Also Does Not • Cost extra money over time • Require extra coats of coating every year • And we do not work as designed if • Kefa is top coated by any other coating that would  bury our special coating underneath, thereby defeating the purpose of preventing condensation from humid air • There are no natural or induced cycles of drying in the environment (e.g. HVAC)

46. Cycle Is Important !!!

47. Why Kefa -- ABC’s • Always work—no power, no “one time only” reaction like intumescent coatings, always “on” • Beautification– avoid unsightly mold, rust, broken concrete, flaking paint • Cost Control from elimination of problems such as recoating requirements, damaged substrates from water, operational interuptions while fixing condensation problem, other….
