The best way to fix exterior concrete window sills in place.

Exterior window sills are traditionally secured or fixed in place with mortar – a mixture of cement, sand, water and plasticiser. The materials are expensive and the labour intensive fixing of the sills in place is also a costly procedure. The objective is to ensure the sills stay firmly in position to support the window frame placed on top. The sills are made to fit snugly to prevent draughts and to provide a pleasant visual embellishment. There are a variety of sills of different materials and textures to provide both an aesthetic and functional role as a foundation for the window to rest on. They are all fixed to a block or brick wall in a similar manner using mortar and or mechanical fixings. Recently new methods of securing the sill in place have emerged in the form of adhesives but in most cases without much success. Until quite recently, none were safe and could not guarantee not staining the sill or window frame itself. They did not comply fully with environmental regulations and were prone to erosion and disintegration. Fortunately a new revolutionary industrial style adhesive/sealant has been developed to replace the traditional fixing method of mortar. It supersedes all other adhesive solutions by offering a formulation that provides a one stop bonding application for practically all adhesion jobs across multiple industries, combining strength with lasting bond performance.
