Mix according to manufacturer’s directions. • Access to joints may require use of boom lifts, scissor lifts, swing stage, scaffolds, ladders, boswain’s chair (sky genie), or bucket trucks to reach heights inside and outside of buildings under construction. • Clean tools using toluene or xylene type products. Specific care and precautions are to be taken when working with these solvent type materials.
