Water repellency is governed by the organic group (methyl group) of the silicone resins. The inorganic portion of the silicone resin "cements" together the filler and the pigment. The super hydrophobic groups project into the capillaries and pores, rendering them water-repellant.
ProPERLA Masonry Creme
Applied white and dries completely clear to protect and retain the appearance of natural facades.
Properla masonry Creme penetrates up to 17mm into the substrate protecting the surface and repelling water offering a self cleaning surface.
ProPERLA Masonry Creme improves the thermal efficiency of the property and is tested to DIN ISO 4108-4 for thermal insulation, proven in tests to reduce energy consumption.
Moisture present in masonry walls speeds up heat transfer from inside the building to outside. However. Properla masonry Creme has unique properties to create a dry masonry wall, slowing down heat movement, therefore helping to keep fuel bills and energy consumption down.
The red area in this thermal image demonstrates the severe heat loss through the damp masonry.
The blue area in this image demonstrates how when drying out masonry walls thermal efficiency is improved resulting in lower energy costs.
Hygrothermal performance is the combination of moisture (in masonry walls) and heat (loss through building surfaces).
It is a proven fact that wet walls transfer heat twice as quickly as dry walls.
Properla will help reduce the moisture content within the walls, which in turn will slow down the transfer of heat. Resulting in lower energy use. Properla is tested to EN ISO 15148.

ProPERLA Self cleaning
In nature the Lotus Leaf completely repels dirt and water due to its unique micro-structure, through the development of technology Properla coloured and clear wall coatings are able to replicate this super hydrophobic effect.
Properla is available in a range of colours
Water Lily, Devon Stone, Pebble, Beige, White, Polar White, Cotswold Stone and Cotswold Cream .
