Cementone No. 2
Integral Waterproofer

DESCRIPTION

Cementone No. 2 is an integral liquid waterproofing admixture for incorporation into concrete or cement
mixes to reduce water permeability under hydrostatic pressure, thus facilitates the construction of water fight structure where aggressive water pressure is present,
like, basement, water tanks, water retaining or containing structure.

Cementone No. 2 Liquid is an alkaline soap of mixed fatty acids compounded to a soft easily dispersed solution.

Cementone No. 2 Powder is based on a dispersion of a saturated aliphatic carboxylic add reacted in-situ to form
a hydrophobic soap, the whole :being carried on the surface of a siliceous flier, to aid ease of dispersion into the cement mixes.

TYPICAL PROPERTIES

  • Initially alkaline, has no corrosive effect on reinforcement in mass concrete.
  • Is economic and convenient to use.
  • Is water repelling to reduce penetration.
  • Is water retentive and thus aids cuing, ensuing maximum strength.
  • Is as durable as the mix into which it is
    incorporated
  • Reduce attack by water-borne aggressive conditions.
  • Help reduce the formation of efflorescence and lime bloom by restricting moisture movement.
  • Help reduce crazing in rich mixtures by controlling rate of water evaporation.
  • Readily available in Liquid and Powder form.

SPECIFYING

"Cementone No. 2 Powder or Liquid" should be specified
by name and used as per site work below.

APPLICATION

Cementone No. 2 may be used in any situation where it
is necessary to construct Cement based sections
resistant to water pressure, e.g. retaining walls, basement, footings (particularly in the presence of aggressive ground water), floor and roof, swimming pools and reservoirs.

They may also be used to kill suction in backing coats,
and in this respect are particularly useful when thin dragged-finish renderings are to be applied as decoration.

Structures containing Cementone No. 2 may be
decorated by any conventional means including all Cementone decorative products. Structures containing Cementone No. 2 are not vapour-proof and therefore where applicable a suitable vapour-proof membrane
should be included.

Air entraining plasticisers and accelerators should NOT be incorporated into mixes containing Cementone No. 2 Integral Waterproofer. Do not over mix the cement mixes incorporated with Cementone No. 2.

SITE WORK

New brickwork to be rendered should be left with raked mortar joints to form a key.

Old brickwork, concrete or rendering should be raked out or hacked; existing plaster and decoration must be removed. Make good loose areas of rendering and ensure backing is clean.

To obtain maximum adhesion, apply a spatter coat of a slurry composed of 1 part ordinary Portland Cement, 1 part sand gauged with a mixture of 1 part Cementone No. 8 to 8 parts of water. In situations where there is no water pressure from the backing, a Cementone Superbond SBR "Key Coat" maybe used as an alternative to the spatter coat and hacking

CLEANING OF EQUIPMENT

Clean tools and other equipment with kerosene.

SAFETY PRECAUTION

  • Avoid direct contact with eye and skin.

  • Wear gloves and goggles.

  • Wash skin or affected area with clean water.

  • Avoid ingestion.

  • Avoid naked flames/sparks and use in well ventilated areas as Marlease contains volatile solvents.

  1. Waterproofing Structures against Ground Water Pressure Rendering should be composed of 2'/2 to 3 parts clean and sharp sand conforming to BS 1199 to 1 part cement by volume. Add 2 litres Cementone No. 2 Liquid or 4 kg Cementone No. 2 Powder per 100 kg cement and gauge the mix as stiff as possible to minimise the risk of cracking of this rich mix. Never apply a strong mix on a weak backing. It will not normally be necessary to add a mortar plasticiser to a rendering containing Cementone No. 2 - Apply renderings in two coats at a total thickness of between 20 to 25 mm (approx. 3/4" to 1"). Roaring should be laid at a thickness of 35 to 38 mm (approx_ 1'/ ") and be composed of 1 part Ordinary Portland Cement to 21/2 parts clean sharp sand or 11 /2 parts clean sharp sand and 2 parts 10 to 12 mm (approx. 1/4" to 3/8") granite or shingle aggregate. I litre of Cementone No. 2 liquid or 2 kg Cementone No. 2 Powder should be added per 100 kg of cement and the mix should be gauged dry.

SAFETY AND PRECAUTIONS

Cementone No. 2 Liquid Alkaline liquid: Avoid prolonged skin contact. See container for full details. Cementone No. 2 Powder Prolonged exposure to dust may cause some irritation as the material contains rime.

It is recommended therefore that the Powder be used in well-ventilated conditions and that normal powder handling precautions should be taken.

With extensive handling in large quantities it is recommended that a dust mask be worn, but for normal usage this is unnecessary. See container for full details.
