DESCRIPTION:

Floor hardener (EMALITE)  is  a  specially  graded  emery  grit  (mineral aggregate) which admixed with cement ,  to  provide  a  high  abrasion  and  wear  resistant  hardest  surface  to  flooring’s  and  paving,  which  will  remain  dust proof,  waterproof  and  grease proof.  It does not affect the setting times  or other properties of the cement, with which it  is mixed.

FEATURES OF FLOOR HARDENER :

• • Provides  built  in  wear  resistance  and  produces  high  abrasion  resistant  floor  surface.
  • Extreme  surface  density  resists  oil  and  water penetration.
  • May be used in open and continuously  wet areas.
  • Non? rusting and easy maintenance.

USES:

By  the  use  of  this material (emalite)  the  top  surfaces  of   flooring and paving can be made wear resistant  and dust proof.  It is ideally suited for use in all  types of industrial floors, which are subjected to  heavy  trucking  and  load  movement.  Floor hardener can  withstand the impact load due to movement of  heavy load over the floor topping.  It is specially  recommended in heavy engineering factories or  as workshop floor toppings, in warehouses and  gangways  where  trolleys  with  metal  wheels  or  fork lifts carrying heavy load frequently .

PACKING :

FLOOR HARDENER (EMALITE) is available in 25 kg.  HDPE / Gunny bag.   

SHELF LIFE  :

If stored in unopened sealed bag a shelf life of  approx. one year could be expected.

METHOD OF USE OF FLOOR HARDENER:

MIXING PROCESS   
FLOOR HARDENER is dry mixed in the ratio of 2 : 1 with  cement  broadcast  evenly  over  the  surface  of  freshly  laid  concrete  and  then  trowelled  to  an  uniform  and  smooth  finish.  HARD SEAL  liquid  surface hardener should be applied to the finish  surface.  (The application should be as detailed in  HARD SEAL data sheet).

APPLICATION DATA:

Floor concreting  The  floor  concrete  should  be  structurally  sound  and  placed  in  accordance  with  good  concrete  practices.  The Water :  Cement ratio should be  kept to a minimum consistency with the need to  produce  a  fully  compacted  concrete  without  excess  water  coming  to  the  surface.  Particular  care must be taken at the corners and edges of the  bays,  hand  ramming  and  firm  trowelling  being  carried  out  to  ensure  that  the  level  can  be  maintained throughout the subsequent trowelling  operations.

Mixing & Application:  100  kg  of   EMALITE FLOOR HARDENER  and  50  kg  of  Portland  Cement  should  be  thoroughly  dry  mixed  on  a  clean, flat surface.  Water must not be added.   Always  use  full  bags  of  FLOOR HARDENER to  ensure  consistent grading.  Any  FLOOR HARDENER /  Cement  mix  left  over  can  be  stored for use the next day providing it is kept in  air tight containers.  Any of the mix left exposed  must not be used, as air setting of the cement will  have  occurred.

The FLOOR HARDENER  EMALITE  /  Cement  mix  should be broadcast in two equal stages, evenly  over the surface of the freshly laid concrete as  soon  as  the  surface  water  has  evaporated.   Immediately after each stage of broadcasting of   EMALITE  /  Cement  mixture  the  first  trowelling  should be carried out, either by hand or by means  of  a  power  float.  When  the  surface  has  sufficiently stiffened a second trowelling should be  given  to  close  any  pores  and  remove  any  undulation in the surface.    This should be followed by a final hand trowelling  to  remove  any  disc  marks.  The  floor  must  be  thoroughly  cured  for  a  minimum  period  of  10  days.

DOSAGE:

This varies from 3 kg  ?  9 kg per m2 depending on type of floor as follows :

• • Moderate duty         =  3 kg /m 2
  • Heavy duty               =  6 kg /m 2
  • Extra Heavy duty    =  9 kg /m 2

Note:  The amounts are for FLOOR HARDENER EMALITE only; it need to be  mixed  with  50%  Portland  Cement  before you  apply it to the floor surface.

PRECAUTIONS:

• • Always store in dry place and in unopened  sealed bag .
  • Proper surface preparation is the essence  of proper  EMALITE Floor Topping.  Dry  cement should not be sprinkled over the  wet  surface  for  finishing  purpose & final trowelling should not be done until  the initial set has taken place.
  • The  EMALITE  topping  should  be  kept  damp with wet gunny bags for minimum  period of 5?7 days.  The  EMALITE topping  should  be  laid  by  a  very  skilled  mason/workman  who  has  knowledge  about  laying  this  type  of  floor  topping.   For  finishing  purposes,  a  steel  trowel  should always be used.

SAFETY:

Use normal safety precautions.  Wear rubber  hand gloves, safety shoes and safety goggles  while using and handling the product.  Avoid  contact with skin and eyes.  In case of  accidental contact with eyes, wash with plenty  of water and seek medical treatment  immediately.
