1c premium gun foam PUP BS 750 B2

The one-component gun foam with proven resistance to water pressure

The fischer gun fountain foam Premium PUP BS 750 is particularly suitable for the sealing and joining of concrete manhole rings and saddle joints as well as the insulating and filling of wall penetrations, cavities, wall connections and finished elements. The foam means that there is no need for the time-consuming application of mortar. The high resistance to dilute chemicals and mineral oils, acids and bacteria found in soil, and rot all guarantee the lasting function of the product. Water pressure resistance testing offers additional reliability. The beige fischer one-component gun foam PUP BS 750 dispenser is fitted with an improved standard valve that increases the product shelf life. Protective gloves for end users are included.
