Cement Render

A basic sand and cement render is, by nature, very weak. Too much cement and it becomes very brittle and not able to deal with thermal expansion and contraction or too much sand can lead to it holding water against the wall.

Due to their weak nature it is recommended that such coverings should only be applied at a temperature of 5°C or above and should only be carried out during dry conditions.

Redecoration of cement renders needs to be carried out approximately every 2 – 3 years. Without regular maintenance moisture will penetrate and it is possible for 1 M² to hold up to 2 gallons of water.

When moisture has penetrated freezing occurs causing loss of adhesion to the wall and eventually causing large sections to fall away. Repairs are very noticeable with this method of covering.

Once penetration has occurred water vapour in the home cannot easily escape through the walls and will be ideal conditions for black spot mould.
