M-1 adhesive is a solvent-free, polyether sealant designed for undesirable climates in construction sites. Whether the site is dry, damp, cold, or wet, M-1 is the ideal solution. Using a non-shrink formula, M-1 does not outgas or bubble on damp surfaces and is even capable of joint movement over 35% in either compression or extension. Performance standards available upon request. 
 
M-1 adhesive can be applied vertically and overhead with no slump and no specialized tools, equipment, or mixing required. It has a 20 minute skin over time and is paintable within 24 if necessary. M-1 can be applied in temperatures as low as 32 degrees Farenheit (0 degrees Celsius). 
 
M-1 adhesive is the recommended adhesive for application of manhole or inlet/shim PRO-RINGs.
