Quantity:
Suremix Mortar Plasticiser, aids work ability in mortar whilst maintaining compressive strength. Helps to prevent crazing, gives improved water resistance and frost resistance to -2°C in the wet. Still based on Vinsol Resin to give the best performance.
BS 4887.
Rate of Use guide:
70cc-140cc per 25kg cement.
Suremix Plus is a advanced formulation Mortar Plasticiser complying to BS4887 part 1 designed to replace or comple ment the use of lime in sand , cement bricklaying and render mixes.
As an admixture in bricklaying and rendering mortars where improved workability and durability is required. Can be used in both cement, sand and cement, lime, sand mortars (BS5628 refers) Mixes protected down to -2°C in the wet state.
Suremix Plus is normally added directly into the mixing drum or onto the "pile" in the case of hand mixing. Suremix Plus may also be pre-mixed with the gauging water.
Mixing should be undertaken in the normal manner ensuring an efficient mixing action. If hand mixing is to be used the mix should be "turned over" to achieve best plasticising effect.
N.B.: The use of Suremix Plus will result in a significant reduction in water demand compared to unplasticised mixes.
Mix design should be chosen in line with BS5628 Code of practice for masonry part 3, Building Research Establishment Digest 362 or Relevant national standards.
Cement: Lime:Sand mixes which also include Air Entraining Mortar Plasticiser have been found to be particularly durable in accelerated test work.
Dosage: Suremix Plus is added at a rate of 70-140 mls per 25 kg of cement.
This dosage may be adjusted for some sand gradings. Trial mixes are suggested to establish the optimum dosage. Whilst it is undesirable to exceed the recommended dosage, the Suremix Plus formulation has air limiting elements which control the entrained air minimising the effects of over dosing.
Store in cool dry conditions.
