The correct specification for any mortar should consider the structural requirements, nature and condition of the background, site exposure, time of the year and type of finish required. Less porous masonry units and harsh climates require greater mortar strength.


Add only 4 to 5 litres of clean water per bag Pour the water in slowly as the product mixes, using just enough to achieve the correct workability. Mix for 3 to 10 min. mortars may be reworked up to 8hrs. 


Before pointing or building clean and remove all dust and loose material from joints and masonry, and adequately dampen dry or high suction surfaces. Do not use in temperatures less than 5 ºC or over 30ºC
