What is Soudal Soudaflex 20 LM?

Soudal Soudaflex 20 LM is a one component polyurethane sealant specifically developed for elastic joint sealing where long-term flexibility, weather resistance, and movement accommodation are required.

The designation LM stands for Low Modulus, meaning the sealant stretches and compresses easily while placing less stress on adjoining substrates. This makes it particularly suitable for expansion joints, movement joints, façade joints, precast concrete joints, and perimeter sealing around windows and doors.

Unlike rigid fillers that may crack as buildings expand and contract, Soudaflex 20 LM polyurethane sealant maintains a permanently elastic seal that accommodates structural movement while preventing water, dust, and air infiltration.
