Cemplas
Liquid Mortar Plasticiser
Conforms to BS 4887 Part 1 : 1986

DESCRIPTION

Cemplas is a chloride-free liquid mortar plasliciser.
It is a resin-based air-entraining agent that improves the workability of cement mixes and providing frost-resistance after-set Cemplas is superior to using rime in cement mixes as it reduces "rime bloom" and efflorescence.

Cemplas is recommended for use in brick-laying, pointing mortar, rendering, plastering and backing coat.

TYPICAL PROPERTIES

  • Improves plasticity and increases ease of application.
  • Reduces rime bloom.
  • Maintains optimum air-entrainment even in the case of over-mixing.
  • Enables the mortar to accommodate accidental over-dosage.
  • Economy of use as compared with rime, induced cement mixes.
  • Reduces glazing.
  • Increases frost resistant property of the set mortar.
  • Improves durability of the mortar.
  • Reduces the water' content of the mortar.

APPLICATION PROCEDURES

  • Reference should be made to the appropriate British Standards and Codes of Practice to ensure correct material selection and adoption of satisfactory procedures in producing: the mortar. General plastering work.
  1. Add Cemplas to the gauging water at the rate of 250 to 500 ml per 100 kg of cement, then pour to the dry mixed cement mortar.
  2. Mix thoroughly to ensure maximum plasticity.
  3. For bricklaying, the strength of the selected mix should approximate the brick.
  4. For internal & sheltered external renderings, a mortar mix of 1 : 6 + Cemplas is recommended.
  5. For exposed external rendering, a mortar mix of 1 :41/2 + Cemplas is recommended.
