Arcocrete

Acrylic Polymer Modified Cementatious Coating for Water Proofing

ARCOCRETE, is an acrylic based Polymer Modified Cementitious Flexible Composite coating system. ARCOCRETE in conjunction with cement provides properties to combat the shortcomings of plain cement, particularly its poor adhesion properties, low impact strength, low flexural strength and thin section fragility. ARCOCRETE polymer adds to the potential use as well as enhances the properties of cement slurry/ mortar/concrete making them excellent choice for use in new as well as renovation work.

Unique Features

  • Combines a tough, flexible, hard-wearing surface with waterproofing.
  • Allows trapped vapor to escape thus preventing peeling and blistering.
  • Can be applied in uniform thickness to horizontal and vertical surfaces.
  • Develops excellent bonds to most building materials.
  • Reduces or prevents salt penetration into the concrete.
  • Is not affected by ultraviolet light or by chemicals ranging from mild acids to strong alkalies.
  • Is highly durable in continuous wet conditions.
  • Is non-flammable and does not give off toxic gases, when exposed to fire.
  • It will not rot or corrode.
  • Most properties improve with age.
  • Is not harmful to the health of the workman.

Surface Preperation & Method of Application:

Surface Preparation
Prior to application of ARCOCRETE, surface must be prepared as mentioned below to avoid failure and to achieve maximum beneficial properties.

  • The surface shall be cleaned to remove all dust, foreign matters, loose materials or any deposits of contamination which could affect the bond between the surface and the ARCOCRETE coating. This can be done by scarifying, grinding, water blasting, sand blasting, and acid washing or by any other approved method.
  • New flat surface like sub-base concrete shall be made reasonably smooth so as not to impede the application of ARCOCRETE coating and to avoid sharp projections.
  • All concrete surfaces shall be thoroughly pre-wetted prior to the application of ARCOCRETE coating by pouring water on flat surface or by spraying water on vertical/inclined surfaces.
  • When placing ARCOCRETE coating, water should be removed so that the surface is only damp. In no case there should be standing water.
  • Depressions are to be filled and levelled using ARCOCRETE fillers. For filler, the mixing ratio is 1 kg cement: 1.5 kg silica sand: 0.50 kg of ARCOCRETE.

Application

ARCOCRETE polymer is mixed with neat fresh cement in the ratio of 1:2 by weight. The mix has to be stirred thoroughly until smooth homogeneous slurry is obtained. Wait for 5-10 minutes to release entrapped air bubbles. Any lump found in the mix should be removed or mixed thoroughly. The mix has to be applied by brush on rendered and/or prepared surface. Two or more coats are recommended. First coat should be allowed to air dry for 5-6 hours prior to apply subsequent coat.

Curing

After application of final coat of ARCOCRETE, initial air drying shall be done for 2-6 hours. During this period no water is to be used for curing. In case of high temperature and low humidity combined with high wind condition, the coating shall be covered with polythene sheet to avoid rapid drying of the coating. After maximum period of 6 hours after the final application, moist curing shall be done for the next 24 hours by spraying/sprinkling of potable water on ARCOCRETE coating.

During this period at no point of time should the ARCOCRETE coating be left completely dry or submerged in water. Following moist curing, the ARCOCRETE coating shall be allowed to air dry for 2 days before submersion in water.

Precautions

  1. ARCOCRETE system must be applied with temperature above 10. C and below 40. C.
  2. ARCOCRETE should not be used without addition of cement.

Storage

Store in dry cool place in the temperature range from 5.C to 30.C in sealed condition. Do not allow to freeze. Keep away from direct sunlight.

Packing

1, 5, 20 & 50 Ltr. plastic container.
