Frequently Asked Questions
What do we mean by breathable?
Breathability is a term used within the building industry to describe how a substrate allows water molecules and air molecules to pass through it. Our independent scientific testing confirmed that Emperor products had little effect on breathability and did not restrict the movement of air.
How have Emperor Paint products been tested?
The Emperor range of products have been independently tested by a United Kingdom Accredited Testing Laboratory (UKAS) to confirm their performance. The products were awarded four certifications; EAD 040083-00-0404 (external thermal insulation composite), EAD 090062-00-0404 (25 year hygrothermal performance), BS EN ISO 12572 (water vapour resistance) and BS EN ISO 7783:2011 (water vapour diffusion).
What is the coverage of Emperor Masonry Paint?
It varies on different substrates, but generally Emperor Masonry Paint rate of approximately 5-6m² per litre. Specific details about the coverage of each of the products can be found on the datasheet, which can be downloaded on the help & advice page.
Can you apply Emperor Masonry Paint over pre-painted bricks and substrates?
Emperor Masonry Paint can be applied on to both pre-painted and non-painted exterior walls. Simply use our Emperor Masonry Primer for bare non-painted walls in order to ensure adhesion.
How do you apply Emperor Masonry Paint?
Emperor Paint products can be applied using a brush, roller or airless spray machine. Specific details about how to prepare the surface and how to apply the products can be found on the datasheet, which can be downloaded on the product page. Alternatively we have a video which outlines each stage of the painting process on our help & advice page.
Can I apply Emperor Paint in low temperatures?
Yes, but it cannot be applied in temperatures less than 5°C.
How long should I leave before painting the second coat?
Emperor Masonry Paint can be recoated after approximately 12hrs at 20°C. Leave slightly longer depending on the temperature.
How soon after raining can it be applied?
Once the surface is completely dry, which will depend on the air temperature at the time. You should know when the surface is dry when there or no visible marks & it is dry to the touch.
What finish does Emperor Masonry Paint leave?
Emperor Masonry Paint is a matt finish.
How long does it take to start working?
This obviously depends on the environmental conditions at the time of application, but generally Emperor Masonry Paint will be dry after approximately 2 hours, and will show it's full beading effect after 24 hours.
