General application and uses
Masons Mortar Ltd Colour Packs are produced specifically for use with Masons Mortar Ltd and certain St Astier dry bagged mortar products to produce accurate through coloured mortars for all aspects of building pointing and repairing masonry, natural stone, brick or cast stone, for render or plaster in conservation, restoration and new build.
The contents of Colour Packs will not affect the overall performance of any product with which they are designed to be used.
It is the sole responsibility of the user to check that the coloured mortar once mixed is an accurate representation of the colour ordered. Once mixed and applied materials will not be replaced.
Colour packs will not affect mortar performance except for the extension of board time or curing when deep reds and dark grey or blacks are used. Consult Masons Mortar Ltd chart for physical properties for the range of Masons Mortar Ltd ready mixed Lime mortars or St Astier compatible dry bagged mixes designated suitable for use with Masons Mortar Ltd Colour Packs.
Ambient and materials / surface temperature range to be within 50C – 300C – out with these ranges consult our Technical Department. Use control methods to maintain ambient conditions until mortar is sufficiently cured – where advised on the Colour Pack Supplied, extend the curing and protection for not less than 24 hours.
· Mix the full bag or unit of mortar to a consistency drier than would normally be required for use, add powdered materials to water wherever possible, start mixing wet, and gradually add more product until the mix reaches the desired consistency, add the correct size of colour pack for the unit size being mixed. Form a hollow in the body of the premixed mortar, in still air – sheltered; ensure the dry contents of the polythene bag are emptied carefully in the mix. Turn over with a gauger or trowel to incorporate the colour pack contents into the wet mortar. Avoid turning the mixer on in case any dry product is lost to atmosphere. Take the colour pack, turn it inside out inside the static mixing drum and wipe it against the wet mix to ensure all pigments are fully integrated. Turn on the mixer, do not short mix, short mixing requires greater water content and will lead to bleed or shrinkage. Over mixing can result in weaker mortar. As a general rule mix for 3-4 minutes with drill and whisk mixers and for 5-6 minutes for pans and paddle mixers. For free fall mixers mix 8-10minutes. If hand mixing, mix all the materials supplied making sure the mortar when slicked with a trowel is streak free, if the mix exhibits coloured streaks, then it is not adequately mixed, usually around 4-5 minutes of vigorous mixing after the final water content is necessary for a good hand mix.
