Appearance
White Marblite Pool Plaster produces a uniform white surface in the swimming pool,
with some slight surface colour variations. When viewed from a distance the pool
has a crisp light blue appearance.
Black Marblite Pool Plaster produces a natural looking effect with some more pronounced
surface colour variations of black marble. Giving the surface the effect of natural
black marble. Black marblite is ideal for natural rock pools and ponds as well as
the very formal Roman type of swimming pool.
Coloured Marblite produces very attractive different coloured swimming pool effects.
When viewed from the edge of the pool the surface of the Coloured Marblite has a
more “Stone Washed” natural marble effect. The close up surface appearance is less
uniform than that of White or Black Marblite, but viewed from a few meters away
the pool has a beautiful natural appearance.
Application
If the plasterer so wishes, Calcium Chloride Flakes may be added to the mixture
of the White Marblite Plaster.
No Calcium Chloride Flakes should be added to the Black Marblite or Coloured Marblite
mixes.
Once the swimming pool has been filled with water, Calcium Chloride Flakes should
be added to the pool water to bring the water’s Calcium hardness up to +- 400 PPM.
This applies to all Marblite plaster finishes.
Our proprietary product “Plastomar Colour Glo” should always be used with Coloured
or Black Marblite Pool Plaster as it enhances the colour and prevents discolouration
of the pool plaster.
Plastomar Colour Glo
The purpose of Plastomar Colour Glo is to enhance the colour and prevent discolouration
of Coloured Marble Pool Plaster.
Plastomar Colour Glo helps prevent efflorescence.
Plastomar Colour Glo renders the Marble Pool Plaster highly resistant to capillary
action.
Plastomar Colour Glo combines with the lime in the Marblite Plaster to form water
repellant particles. These obstruct the capillary action within the Marblite Plaster.
Plastomar Colour Glo is a water reducing plasticiser which lubricates the mix, making
it far more plastic and workable than usual.
1 Litre Plastomar Colour Glo per 25 litres of water used to mix the Marblite Pool
Plaster.
Coloured Marblite marks and streaks
Due to the Lime which is present in the cement of all marble plasters, white streaks
and marks sometimes appear on the surface of the coloured marble plaster. To remove
these surface streaks and marks the pool should be drained after four weeks and
the marble plaster sanded down using a 115mm resin fibre flexible disk (this is
the flexible disc as is used on a small angle grinder) with the grit rating P36.
It is better to sand the pool by hand using this 115mm flexible disc – grade P36
than to use the grinding machine as the operator may cut into the plaster if not
careful.
Application of marble pool plaster
Surface preparation
Should be clean and free of loose particles. Suitable surfaces are Gunite; rough
concrete and rough wood floated Portland Cement plaster. Blastfurnace Slag should
not have been used in construction. Wet surface with clean water before plastering.
Mixing
The Marblite is mixed with clean water, incorporating Plastomar additive, to a stiff
workable plaster. Marblite should NOT be mixed to a sloppy mixture. (The less water
the better).
Coverage
A 40kg bag of Marblite will cover approximately 2.25 sq. mt, at a thickness of +-
6mm. The average pool of 4.5m x 9m requires approximately 35 bags of Marblite.
Application
The Marblite is applied to the walls of the pools with a steel trowel to a thickness
of approximately 6mm. When the Marblite begins to set after +- 30 minutes it should
be re-troweled. Later, when the Marblite has almost set it is again re-troweled
to the final smooth finish. For the final trowelling a steel trowel with rounded
corners should be used. If necessary, wet the Marblite surface slightly, or use
small amounts of freshly mixed Marblite to obtain the final smooth finish. Beware
not to overtrowel as this can cause black trowel marks. After the walls have been
plastered continue with the floor. The entire pool should be done in one day.
Filling with water
The pool should be filled with water +- 12 hours after plastering with Marblite,
but should be protected from rain and frost for at least 6 hours after plastering.
Care should be taken not to get any mud stains onto the uncured Marblite plaster.
The pool is filled by placing a hosepipe into a plastic bucket at the deep end of
the pool. Exposed surfaces of the pool should be kept damp until the pool is completely
filled with water. To prevent leaching or staining of the plastered surface the
calcium hardness of water should be adjusted to +-400mg/l (PPM). On a 50 000 litre
pool 10kg of calcium flakes may be added to the pool water, through the weir.
