find for many years so-called "pavement joint mortar" (eg with epoxy) used for strengthening joints on sidewalks, driveways and terraces.
Here there 1 or 2 component versions, ready mixed in pails or in bags for mixing in the machine.
all have one big problem: almost always remain after the application of contaminants on the plates visible, sometimes as a change in color or gloss residue, or both. If
now prevail in the laying poor working conditions (high temperatures) and the work is not very clean, this results in a totally irregular appearance and the surfaces appear blotchy. These residues
smell after a few months (sometimes only after one year) somewhat, but a big problem with partially covered surfaces. The normal sist on terraces. The covered area is virtually stained, while the lining is on the open space brighter.
remedy here, treatment with S- FUG before grouting. Through this pre-impregnation can the existing mortar joints in the binder does not "eat their way" into the stone and the turning away of the mortar is significantly simplified. A uniform appearance is guaranteed and in addition, some protection of water and oil repellent effect on the pads.
However, to ensure total protection for the pads is recommended a final treatment after completion.
The pre-impregnation can be easily applied with a sprayer, brush or roller - best one day before introducing the pavement fixing mortar.
S-FUG is also ideal for protecting surfaces that are prone to discoloration due to moisture during installation. Ideal as a Verfugungshilfe for very absorbent stone, inside or outside.
to be additional material costs must be about 1.00 € / sqm expected, this one should be worth the uniform appearance.
By facilitating the cleaning of the joint material will also save these costs very easily.
