Q: What is the minimum / maximum temperature at which your render can be applied?

A: The minimum at which render can be applied is 5°C. At lower temperatures the possibility of water freezing may cause problems such as cracking and de-bonding of the render. The maximum temperature at which render should be applied is 35°C. At higher temperatures the render would need to be applied in shaded areas, the substrate may need cooling with a mist spray of water.

Q: How far does a bag of ‘x’ go?

A: Coverage of materials is on relevant data sheets. The coverage depends on the thickness applied. Details of the amount of mixed material is on the bag in litres.
For more information please use our Consumption Calculator.

Q: Can I render onto a previously painted surface?

A: Not directly. Render will not bond to a previously painted surface so you would need to either remove the paint or consider our range of EWI systems.

Q: What type of block do you specify for your render?

A: Weber do not specify the type of substrate. Whatever block chosen should be of sufficient strength and density to receive the render being applied. If in doubt the relevant block manufacturer should be consulted as to the suitability. As a guide Weber monocouche through coloured renders are equivalent in strength to a designation III mix.

Q: What movement joints are needed in your render?

A: Movement joints are required by the substrate and should be followed through the render. Details of where movement joints are required can be obtained from the relevant codes of practice for masonry construction. If in doubt, advice from a structural engineer should be sought.

Q: Can you give me more details on Lime Bloom?

A: Lime Bloom is a natural phenomenon in cement/lime based products and is neither an application or product fault. For more details on causes and remedial action download our Lime Bloom Technical Advice PDF.

Q: Can you give me more details on cracking?

A: Straight line cracking is not typical of render failure, but rather of the reflection in the render of a crack in the substrate. For more information and suitable remedial action download our maintenance for monocouche renders PDF.

A: The date on the bag is the manufacture date. The shelf life will be on the bag and for most products is 12 months
