For more than 700 years, St Marys Church has been central to the lives of parishioners in the village of Fawkham in Kent. Unsurprisingly, the Grade I listed building has endured several lifetimes’ wear and tear, leading to its façade requiring deserved refurbishment. A National Lottery Grant funded the repairs, which were carried out by contractors, Decretech Decorators. Lee Clifford, Managing Director at Decretech, said: “Baumit’s façade render system was selected for the refurbishment after a member of the church had seen houses renovated with the same material.There was a visible difference between the properties coated with the Baumit system – they looked brand new, the others didn’t.”

With the church requiring a ‘modern, longer-lasting’ look, the initial repairs involved power-cleaning the building’s existing lime-wash façade across its 800m2 surface. To prepare the substrate, Baumit FungoFluid was then applied. Solvent-free, the fluid provides the perfect solution for treating surfaces with fungal or algae growth. This was followed by a coat of Baumit PremiumPrimer, a pre-treatment application for mineralbased and paste-form decorative plasters. It also works as a means
of absorption compensation and bonding agent for a subsequent coating of Baumit plaster, and thermal insulation systems.

Baumit RK39 hydraulic lime render, a proven all-purpose plaster was then applied to make good the repair work. A further coat of Baumit PremiumPrimer followed, before two layers of Baumit NanoporTop supplied a brilliant white self-cleaning render finish. Whilst other self-cleaning products rely on rain or moisture contact to maintain a healthy-looking façade, Nanopor systems require nothing more than sunlight, humidity and wind to provide a uniform, dirt-free surface.




"Baumit’s façade render system is the most superior system

  I’ve used - it was a joy to apply."


The revolutionary ‘Nanopor-effect’ is produced when sunlight activates the photocatalysis additive in the render or paint, affecting the upper-hydrophilic nano layer within the product whilst it dries. During the process, dirt is decomposed and lifted from the surface by air movement. Any remaining particles are removed by rain and evaporation of absorbed dampness to leave a superbly-clean façade. The façade’s renovation was completed in three weeks to the complete satisfaction of all those involved with the church. Lee Clifford said: “Baumit’s façade render system is the most superior system I’ve used - it was a joy to apply. Its cost-effectiveness far outweighs any initial costs. It’s the difference between renovating a building’s exterior every 10 or 15 years, rather than every five years, which has to be more practical for the occupier and better for the environment.”
Thanks to Baumit’s superb façade render system, St Marys Church parishioners will be viewing their beloved historic building in a stunning new light for many years to come.
