Sika’s liquid-applied roofing and waterproofing uses several coating technologies. One-component, cold-applied technologies are high-solids polyurethane, high-solids silicone and Type 1 acrylic. Two-component, cold-applied technologies are polyurea hybrids, with optional polyaspartic topcoats. The two-component, hot-spray-applied technology is pure polyurea.
The named product lines are Sikalastic RoofPro, Sikalastic RoofCoat, Sikalastic Clearglaze, Sikalastic Conductive Primer and Sikalastic 720, together with liquid-applied resins, reinforcements, primers, adhesives and accessories.
Sika arranges these into system configurations. Direct to Substrate covers concrete decks, plywood decks, metal and existing roofs. Built-Up Insulated covers roofs requiring insulation. Plaza Deck, Terrace, Balcony and Patio covers surfaces with pavers, wood decking or tile over the membrane. Green (Vegetated) covers intensive or extensive vegetated overburden. Existing Roof Recover uses Sikalastic RoofCoat. Metal Recover covers standing seam metal roofs. Skylight Restoration uses Sikalastic Clearglaze with RoofPro resins and reinforcement. Chemical Containment, Cooling Tower and Gravel Roof Resurfacing are the remaining configurations. Gravel Roof Resurfacing uses Sikalastic 720, a two-component aromatic urethane mixed with recycled crumb rubber.

Relevant manufacturer history
Kaspar Winkler founded the company in 1910 and invented Sika-1, a quick-setting waterproofing admixture for mortar. The firm, Kaspar Winkler & Co., was entered in the Commercial Register in 1911.
In 1918 Swiss Federal Railways trials used Sika to waterproof Gotthard tunnels, which was a breakthrough for the company. A subsidiary with small-scale manufacturing was founded in Southern Germany in 1921, and subsidiaries followed in England, Italy and France between 1926 and 1928.
By the 1930s the company had 15 subsidiaries in Europe, the USA, Argentina, Brazil and Japan. In 1968 the group became a single corporate structure with Sika Finanz AG, and Sika AG became the holding company in 2002.
In 2005 Sika acquired Sarna, a Swiss membrane specialist. In 2010 Sika marked its 100-year anniversary, operating in over 80 countries with over 15,200 employees.
