Masonry Crème

Keep the weather out & the warmth in

A dry house is a warm house. When the walls of your home get wet from wind driven rain, it decreases the thermal resistance of the walls and can result in increased heat loss, contributing to higher energy bills. Water acts as a thermal bridge causing heat to transfer away from the property, reducing the energy efficiency of your home. 

ProPERLA Masonry Crème is a highly water repellent wall coating which improves energy efficiency by keeping walls dry. When rain comes into contact with coated walls, the water forms water droplets that simply run off the surface, reducing the water absorption of the walls by up to 96.3%.

Independent tests have demonstrated brickwork treated with ProPERLA were significantly more energy efficient than untreated ones. The thermal image on the front, was taken during impendent scientific testing and shows 6*C difference in temperature between sections of the wall treated with ProPERLA and the untreated centre section.

Prevent & Protect

By diminishing water absorption, our clear masonry cream has been proven to reduce soluble salts migrating from bricks and mortar thereby preventing unsightly deposits of salt efflorescence. Whilst salt efflorescence is generally considered an aesthetic problem , it does have the potential to cause structural damage, such as the erosion of mortar joints, known as sulphate attack.


Moisture in the walls of your home can not only cause heat loss it can cause a host of problems for your house, your health and your pocket too. By keeping your walls dry, you can help prevent.

Highly Breathable

ProPERLA Masonry Crème does not restrict the ability of your home to breathe. Independent testing (BS EN ISO 7783:2011) demonstrated the coating had little effect on air and moisture escaping. Unlike some stone and brick sealing products, it does not block the pores of the masonry by coating them with a thin film.


Treated masonry remains clean and attractive – dirt is washed away with rainfall. The lack of moisture in the walls helps to deter the growth of unsightly moss, algae or lichens. 

Great Performance

ProPERLA Masonry Crème has gone through independent tests by UKAS certified body Lucideon and has been proven to meet the following standards;

  • ETAG 034:2012 – 25 year hygrothermal performance
  • ETAG 004;2011 – external thermal insulation composite
  • BS EN ISO 7783 – 2011 – water vapour diffusion
  • BS EN ISO 12572 – water vapour resistance
