Preparation is key to a job well done, and preparing the surface prior to Fibrecoat application is a vital step.

Before applying Fibrecoat you must ensure that the surface area is completely clean, remove any debris including dirt, soil or moss with a power wash or hard brush. Any surfaces that’s had moss and lichen on should be treated with a proprietary fungicidal wash and allowed to dry.

If you are overlaying Fibrecoat onto an existing surface that you must check the surface to remove any imperfections and repair any problems. With asphalt, any flat roof ballast chippings must be removed, however deeply embedded chipping can be left if removing them leads to extensively damaging the asphalt. Badly degraded asphalt must be removed.

Blisters in the existing asphalt surface need to be cut open to expose the surface, this should then be dried and rebuilt with a a cementitious mortar. Remember failure to remove all loose chipping will invalidate the warranty so extra care is required at this stage.

If you are overcoating roofing felt then inspect the roof and look for weak and degraded sections that need to be replaced. Blisters in the existing roofing felt need to be star cut and with the surface exposed, dried and the felt re-bonded to the substate.

The Fibrecoat system can extend up to and over brick work, concrete and parapet walls, if required. Any cracks in these surfaces need to be cleaned out and filled with cement based mortar and allowed to dry prior to coating with Fibrecoat Primer FP4922 in accordance with our product application guide.

Corroded metal surfaces are to be thoroughly wire brushed to remove corrosion and then primed with Fibrecoat Primer FP4922 in accordance with the products application guidelines.
