Secure Non Pick Mastic Sealants

We stock non-pick mastic joint sealants (also known as secure grade mastic sealants) for use in applications where a tough, totally secure joint seal is required. Some examples are prison cells, police station holding rooms & classrooms etc. Non pick mastic sealants go off very hard just like cement or grout but offer just a small amount of flexibility whilst the joint seal remains rigid and hard-wearing.
