1 Sika ConstructioNEWS A Newsletter of Innovative Building Solutions Vol 1. May 2013 Dear Valued Customer, We are pleased to bring you the first edition of Sika ConstructioNEWS, A Newsletter of Innovative Building Solutions! It has been roughly twenty years since we did a newsletter. Some of you may remember, it was called Sika News. A lot has changed at Sika since this newsletter was last published. 20 Years ago our focus was SikaTops, sealants and epoxies. Since then we have launched corrosion inhibitors and corrosion mitigation systems, frp strengthening systems, epoxy and cement grouts, fast-set mortars and concretes. More recently, we launched a traffic waterproofing system (Sikalastic 710/715 and 720/745), bought a roofing company and introduced those products (Sikalastic 621 and 624) and bought a silicone sealant company and launched those products (Sikasil WS 290 and 295). ne thing that has not changed: the people! As I read through the last published Sika News, illustrated below, I was excited to see that many of the people mentioned are still with us! We are very proud of that fact. We know it is important to have a great company with great people to stand behind our great products. In order to keep you informed about what is new at Sika, we plan to publish Sika ConstructioNews on a quarterly basis. There are 3 main sections that represent the core of our business: 1) concrete repair and protection, 2) sealants and 3) building envelope. We also plan to include articles that tackle technical issues (Tech Briefs) update you on new acquisitions and make you aware of anything else we think our customers would be interested to know. We hope you enjoy this newsletter. We thank you for your business! Timothy Gillespie Director of Marketing, Contractors Business Unit, Sika USA

Classified as a FIT project by corporate marketing, the contractors BU is excited to add three exciting products to its wide range of multiple product solutions that improve durability of existing concrete. Silane sealers are non-film forming protective material which are applied on concrete with rollers or sprayers. These materials are widely used on bridges, parking decks, buildings to prevent moisture ingress and chloride intrusion, both of which are detrimental to concrete. Contractors Business unit is very active in the market segments of buildings, bridges, parking decks and these new products fit in perfectly to complete other existing water proofing solutions that include epoxy, polyurethane and acrylics.

4 Sika Silicones Gain SWRI Validation SealantNews by Will Hutchison Sika is proud to announce the recent Sealant Waterproofing and Restoration Institute validation of Sikasil WS-295 and Sikasil WS-290, two key products in the Sikasil product range. SWRI is an industry group that verifies product performance through testing to ensure that customers are getting the highest quality products. SWRI approval signifies independently verified product performance in key sealant specifications and reaffirms the quality that satisfied Sika customers have recognized in the field. The tests in the sealant validation program, ASTM C719 and ASTM C661, asses a sealant s joint movement capability, adhesion to different substrates and hardness. These approvals once more demonstrate the industry-leading quality of Sika s sealant products and solutions. Sikasil WS-295 is a high performance, low-modulus and versatile silicone sealant. It gained SWRI validation for a joint movement of +/- 50%, exemplifying its great elastic properties. The WS 295 shines compared to competitive products in SWRI verified primerless adhesion WS 295 passed ASTM C719 unprimed on glass, unprimed on aluminum and unprimed on mortar. This strong performance shows why Sikasil WS 295 is the cornerstone of Sika s silicone line and well respected around the country. Sikasil WS-290 is a high performance, ultra-lowmodulus sealant for use with EIFS and in applications where extreme joint movement is expected. With an ASTM C661 measured Shore A hardness of 12, WS 290 creates very little stress on bond lines, making it perfect for EIFS applications. Its SWRI validated +100/-50% joint movement capability demonstrates the ability to handle high movement joints. Sikasil WS 290 s unique characteristics offer unmatched performance in many sealant applications. Sika is proud to provide industry-leading silicone and polyurethane sealant solutions, and we are happy that Sikasil WS 295 and Sikasil WS 290 are receiving the industry approval that they deserve.

6 Cleaning and Maintenance of Sikaflex Sealants &/or Sikagard Coatings TechNews by Ray Williamson Generally speaking, fully cured Sikaflex polyurethane elastomeric sealants and Sikagard acrylic-based, waterdispersed Facade Coatings are considered low maintenance items. However, if a client wishes to clean the areas where Sikaflex polyurethane elastomeric sealants or Sikagard Façade Coatings have been installed and allowed to fully cure, typically water or a mixture of water and a very mild, bio-degradable soap using a soft bristle brush followed by thorough rinsing with additional water can be used. Do not use solvents or harsh chemicals which could result in the breakdown of the installed material. If pressure-washing / power-washing, use caution by applying the least amount of pressure possible to be effective but not damage or delaminate the sealant or coating. Sika Corporation strongly recommends a trial to determine effectiveness of method and appearance of sealant / coating. Please note the use of cleaners, the activity of wash downs and the weather may alter the appearance of the cured sealant / coating. Recommendations are given only as guidelines, used to assist facility personnel in establishing their own cleaning and maintenance program. For additional information on the particular Sikaflex polyurethane sealant or Sikagard Façade Coating installed, product data sheets and other literature can be viewed at Sika Corporation s website: Should you have further questions or require additional information please feel free to contact Sika s Technical Services Department at , option # 5.
