Alumino-Silicate Glass Fibre Reinforcing Mesh
Description
The special Alumino-Silicate glass fiber mesh is used for the proper binding and structural reinforcement of non-absorbent or absorbent substrates for pre installation of levelling compounds and other covering materials over concrete surfaces and other approved substrates.
The silica glass fibre mesh used in conjunction with epoxy primer Okapox GF and is used as additional reinforcement of various substrates to prevent transmission of damaging shrinkage and stress cracks from the subsurface.
Fiber mesh and the epoxy coating acts as an extremely heavy duty anti- fracture membrane eliminating penetration of stress in to the tiles or other covering materials.
The silica glass fiber mesh combined with Okapox GF provides an additional moisture barrier.

Application Only with Okapox GF - Substrate Preparation
The substrate must be dry, clean and sound. Mechanically remove any oil based or loose products. The existing substrates be prepared as per AS1884 and meet the requirements for moisture control and Planeness, Smoothness and Abrupt Surface Deviation. Levelling compounds may be part of the solution to achieve these requirements. When in doubt contact Polyflor Technical Department on 1800 777 425.
- Processing
Install movement and expansion joints prior to installation. Install a seal gasket around the installation area and its perimeter (keep in mind different obstacles and use a seal gasket around them). Same installation method of the seal gasket is required when installing over non-rigid soft and floating substrates.
Then, roll out the silica glass fiber mesh over designated substrate without any wrinkles. Use micro serrated scissors or a so-called EC-Cutter to cut silica glass fiber mesh. The silica glass fiber mesh should be overlapped by at least 5 cm. Always overlap and install silica glass fiber mesh in one direction.
Mix Okapox GF according to a separate technical data sheet. Then pour Okapox GF in designated area and spread with a flat trowel without moving or wrinkling fibre mesh. Wait until fibre mesh is completely saturated and remove the excess of Okapox GF if necessary. Avoid creating puddles. Let the Okapox GF and fiber mesh completely dry. Should you encounter any imperfections after the proper drying and curing, grind the designated areas down and recoat with Okapox GF.
After the proper curing and drying time, but before first 48 hours from the initial installation; prime the surface of Okapox GF and fibre mesh with undiluted Okatmos® EG 20.
Do not cover existing structural joints which separate individual parts of the building from structural and physical reasons. Same principal applies to expansion or cold joints.
