Stontex Façade Pro500 25L

This product was formulated specifically for natural stone, brick and coloured render used to treat vertical external cladding / facades. It is a very effective fast drying, fully breathable and invisible treatment for external vertical cladding.  Façade Pro 500 will not change the colour or look of your material it is a professional grade high performance penetrating hydrophobic treatment for exterior cladding. Basically it keeps the driving rain from penetrating through the outer leaf cladding solution i.e. stone, brick or render.

The thermal properties of your building are thereby greatly improved resulting in energy retention and thereby saving as well as protecting the cladding material from UV and weather damage. Ongoing maintenance and cleaning is much easier no need for aggressive power washing simply spray our Green to Clean onto your treated cladding once or twice a year for hassle-free clean cladding.

Field Of Application Stontex Façade Pro500 25L

Ideal to be applied using a knapsack sprayer generously saturate the surface and allow the treatment to penetrate into the material for about 10- 15 mins and then buff all the residue from the surface using a fluffy head paint roller. Ensure that the treatment has penetrated into the material and all residue is removed using a dry paint roller head.

Most cladding material is porous by nature some material more porous than others but this 10-15 min dwell time will be sufficient to cover you for all types. Normally one coat is sufficient but for more porous material a second coat can be applied for additional protection. It is recommended that the freshly treated material is kept dry and free from footfall traffic for 3 to 6 hours after application.
