Kerasil mortar is supplied wet in buckets, ready to use. It has a soft consistency and is almost fluid. It coats very well and easily to all surfaces, and sets very hard and strong. It sets rigid and permanent, and should therefore be used with discretion in moving structures.
Kerasil mortar can be smeared, trowelled or buttered, and has particularly good penetration and adhesion. As a brick mortar the soft consistency allows thin joints to be made. As a fibre module cement it gives a considerably larger contact area than normal mortars. Exposed surfaces normally become smooth and exhibit no cracking. A thin dry film develops rapidly on the exposed surface, so bonding should be performed quickly.
Kerasil mortar is 90% pure silica and can be used up to 1300°C. It is light brown when wet, and becomes almost white when fired.
Packaging is in 20kg plastic buckets with liners. Some liquid may be found separated on the top. Mix it back into the paste. Keep the lid closed when not in use. Wash hands well after use and apply a moisturising cream.
Caution: Spillage on the bucket dries very hard and may develop sharp edges which can cut your hands.
Shelf life; About 4 years in sealed buckets.
