SURFACE PREPARATION > The surface of application must be thoroughly prepared by
mechanical means, to remove all loose particles, laitance, etc. > Oil and grease, if any, must be de-
greased with suitable solvents. It then must be washed off with jet of water and brought to touch dry
state. Any surface undulations, cracks and crevices must be duly filled or repaired with cement sand
mortar mixed with latex polymers such as Dr. Fixit Pidicrete URP
MIXING
> Shake the liquid component well to a homogenous milky colour.
> Use heavy duty slow speed mechanical mixer fitted with a suitable paddle for mixing the two
components of
the material.
> In a mixing vessel, slowly add the powder component in to the liquid under continuous stirring.
Continue to
stir thoroughly to achieve a lump free homogenous slurry.
3 APPLICATION
> It is important that any pipe inserts or sanitary fittings should have been fitted grouted with
suitable products
from the Dr. Fixit range well before taking up the application.
> Grout pipe inserts using Dr Fixit Bathseal Tape and Dr Fixit Bathseal Grout.
> It is mandatory that all works of plumbing and sanitation must be complete before taking up
application of
Dr. Fixit Pidifin 2K.
> The surface of application must be pre-wetted thoroughly with water & brought to a touch dry
state. Take
up the first coat application with a stiff nylon brush. Work well into the substrate, to ensure that all
small
undulations are completely filled with the coating.
6 to 8 hrs after completion of first coat, take up second coat application in a direction perpendicular
to the first.
> Complete the application and leave to air cure for 2 days. A moist hessian cloth can be kept over
the coated
surface to protect it from the effect of direct sunlight, in case of bathrooms and internal areas. Leave
the
coating without water curing for 2 days at least.
> In new bathrooms, typically, Dr. Fixit Pidifin 2K must be applied all over the sunken slab portion
and upwards
over the masonry walls up to a height of 6-7 feet, i.e. Over the splash zone of shower, etc. to ensure
complete
waterproofing.
> For vertical walls in bathroom ensure internal plaster level is sound and leveled mixed with Dr.
Fixit Pidiproof
LW+, Apply 2 coats of Dr. Fixit Pidifin 2K on all over or shower area, sprinkle the coarse, quartz
sand while the
second coat is still wet. This will provide key for subsequent tile adhesive materials.
Precautions & Limitations
> Do not part mix. Mix the entire quantity of both the components at one go.
> Do not dilute.
> Always add powder to liquid to avoid lump formation.
> Do not cure by flooding with water.
> Cure the membrane with moist hessian cloths.
> Pond test for water tightness shall be carried out only after seven days of complete and proper
curing
Theoretical Coverage
Approximately 0.6 – 0.75 m2
/ kg at 1 mm thickness in 2 coats, depending on the level of the substrate.
