I undersigned Olivier GRIEU, Director of Technicals services of Bonneuil-sur-Marne city, certify to have brought in GLISS'GRIP company in june 2013 to resolve a slippery wood's problem.

Indeed, the exotic wood decking Massaranduba surrounding the Bonneuil-sur-Marne's media libraby became slippery, especially by heavy rain, and it had caused falls and accidents until now.

To secure this decking, GLISS'GRIP company advised me it anti-slip treatment, especially for wood, GLISS'GRIPBois®.
The Ultragrip version was recommended because of the heavy traffic at the media library.

One of the professionnals applicators of GLISS'GRIP company intervened and after a careful wood stripping, he applied the GLISS'GRIPBois® UltraGrip treatment over the entire surface (around 150 square meters).

After the treatment and 1O months of use, I am perfectly satisfied of amazing anti-slip effect that GLISS'GRIPBois® procure.
The safety around the media library is total and no more falls was deplored.

Moreover, the product completely renewed the aesthetic appearance of wood, by giving it a permanent wet aspect, particularly nice.

So, I can assure that my satisfaction and that of the media library's users about the longevity and efficiency of GLISS'GRIPBois® is total.

Olivier GRIEU, 

Director of Technicals Services of Bonneuil-sur-Marne city (94)
