Perma Plast Clear QS



Perma Plast Clear QS is a silicate based liquid which acts as a plasticising and quick setting agent for cement, concrete and mortar. Perma Plast Clear QS admixed mortars and concretes set fast giving early and final high strength. Perma Plast Clear QS is of special use in plastering mortar, shot-creting, guniting and concreting in very low temperatures.


  • In fast setting concretes and mortars.
  • Concreting of pre-cast elements.
  • Concreting and rendering in very low temperatures.
  • In reducing rebound losses in sprayed mortar.
  • To waterproof plaster and concrete.


  • Perma Plast Clear QS is of special use in plastering mortar, guniting and shot-creting as it accelerates the setting time to help in quick rebuilding of mortar layers without collapse.
  • Rebounded losses in plaster mortar, shot-creting and guniting are minimized. Early shifting of the pre-cast elements is facilitated.
  • In pre-cast hollow solid blocks, pavers, cement tiles, breaking of the edges while lifting the moulds in minimized.
  • Perma Plast Clear QS helps in early setting of mortars and concrete in low temperature climates.


In case of shot-creting/guniting, Perma Plast Clear QS is mixed in the gauging water in the required proportion before addition to the dry mix. Hence it can be successfully used in both dry and wet shot-creting processes, in concrete and mortars for pre -casting elements. Perma Plast Clear QS is dosed through a separate dosing tank fitted above the mixer. It can be dosed manually as well after addition of required water.


  • Rebound losses in plastering mortar, shot- creting and guniting are minimized. Saving on material, labour and machine time.
  • Perma Plast Clear QS is in liquid form, hence easy to use.
  • The plasticizing action of Perma Plast Clear QS helps in complete hydration of cement there by achieving superior strength.
  • Wastage due to breaking in pre-cast elements is reduced savings on production cost.
  • Perma Plast Clear QS can be used with all types of cements.
  • To waterproof plaster and concrete.


Required dosage of Perma Plast Clear QS has to be arrived at site by practical trials. The dosage is dependent on temperature conditions, type of cement, type of acceleration required. We however recommend dosages of 1 to 10 percent by weight of cement. Lower dosages are however used in pre-cast elements and higher dosages are used in shot-creting. For waterproofing the minimum dosage of the product shall be 250 gms/50kg bag of cement.

Perma Plast Clear QS is based on refined silicates and synthetic plasticizers.


  • Over dosage of Perma Plast Clear QS results in flash setting of concrete or mortars.
  • Do not use frozen aggregates in concreting in low temperature areas.
  • For best results keep gauging water to a minimum .
  • Areas to be concreted or shot-creted should be free from ice.
  • Fresh concrete should be so sheltered as to ensure the preservation of heat of hydration evolved.
  • The result laid down by concreting authorities for cold weather should be strictly followed.


Perma Plast Clear QS is compatible with all types of Portland cements including sulphate resisting cement. For use with other cements and along with other admixtures please seek the advice of your nearest Perma technical officer or Distributor. Perma Plast Clear QS should not be premixed with other admixtures. If other compatible admixtures to be used in concrete then does them separately.


Perma Plast Clear QS is not a health hazard or fire risk. Spillages should be washed immediately to avoid possibility of slipping.


Perma Plast Clear QS is available in 30 kg, 120 kg and 250 kg HDPE packing.


Perma Plast Clear QS has a shelf life of 24 months if stored in manufacturer’s original packing.
