Profile has to be laid on fresh epoxy or PCC mortar.
The enticement layer has to be realized in order to respect the alignment between profile and finished floor superior line. After this first step profile’s wings have to be fixed through supplied screws.
It is very important to verify that profile is straight and perfectly levelled so that its superior corner can be at the same level of tiles or floor in general. Fixing has to be done in parallel on both profile’s sides each 30 cm.
Profile will work in the right way only if both wings are weel-fixed to the substrate.
Connection of production length profile is obtained by staggering the joints in the individual aluminium profile.
Insertion of central rubber part can be


helped using some water added with soap.
The central insert has to be installed starting from one end and a roller can help during this phase.

Don’t use a hammer as it could damage the profile.
Before central rubber insertion, it is very important to check brackets’ runners are free from dirt.
