*RPM/Belgium N.V. - Version 2 - 04.06.2007 - MONILE GBPropertiesCompressive strength:Is an index of the ability of a substance to carry a load without flowing or rupturing.

Monile has a compressive strength of 70 N/mm2 (700 kg/cm2), MORE THAN TWICE THAT OF AVERAGE CONCRETE!

The compressive strength is much influenced by the right size of used quartz, cement and used polymer.


*RPM/Belgium N.V. - Version 2 - 04.06.2007 - MONILE GBPropertiesTensile strength:Is an index of the ability of a material to hold together under tension.

The square of tensile strength is an indication of the impact and abrasion resistance.

The tensile strength of Monile, is TWO TIMES THE AVERAGE TENSILE STRENGTH OF CONCRETE!

The tensile strength is influenced by the type of polymer and its concentration.


*RPM/Belgium N.V. - Version 2 - 04.06.2007 - MONILE GBPropertiesChemical resistance:Monile is not affected by exposure to blood, animal urine, animal faeces or lard, edible oil, mineral oil, greases, diluted chemicals commonly used in the food industry and alkalis (except in high concentrations).

Resistance to thermal shock:Under thermal shock, the expansion and contraction of Monile is equal to that of concrete. No loss of bond occurs.

After 29 cycles of 30 minutes interval with exposure to water at 80C and 15C => no change is observed.


*RPM/Belgium N.V. - Version 2 - 04.06.2007 - MONILE GBPropertiesResistance to temperature fluctuation:After 12 cycles of exposure to cooling from temperature to -40C during 2 periods of 3 hours with 2 hours pause in-between, the Monile remained unchanged.

Health regulations:Monile complies with the requirements of USDA and EEC health authorities.

Large areas can be placed without joints. Only structural and construction joints need to be taken through the Monile screed. This maintains high standard of hygiene.


*RPM/Belgium N.V. - Version 2 - 04.06.2007 - MONILE GBPropertiesSafety in use:Many floors have excellent antislip properties as long as they are dry. As soon as they are wet or greasy they become very slippery and dangerous. Monile, due to its inherent slip resistant properties, remains safe and non-skid even when covered by water, grease, fat

Easy maintenance:Monile resists to the normal detergents and alkalis used in conjunction with hot water or steam for the daily or more frequently maintenance of the floors.


*RPM/Belgium N.V. - Version 2 - 04.06.2007 - MONILE GBPropertiesDurability:The best way of analysing the durability of a material is to look at old installations. The oldest in Europe dates from 1962 an is still in good condition.

*RPM/Belgium N.V. - Version 2 - 04.06.2007 - MONILE GBApplicationThe surface should be clean and cohesive.

The concrete should have a minimum compressive strength of > 30 N/mm.

Degreasing in case of oils and fats. In case of light contamination, steam cleaning with detergents can be very efficient. Never use solvents, because they tend to push the oil and fat into the concrete. In case of serious contamination, flame cleaning followed by mechanical grinding is required.

Preparation of the substrate


*RPM/Belgium N.V. - Version 2 - 04.06.2007 - MONILE GBApplicationMechanical grinding is always required to remove the laitance or to obtain a rough surface for a good adhesion.

After the mechanical treatment, humidifying of the substrate is necessary before applying the adhesion layer.


*RPM/Belgium N.V. - Version 2 - 04.06.2007 - MONILE GBApplicationAdhesion layer: mix Monile Liquid (ca. 3.5 litres) with 1 bag of composite (21 kg) until a homogeneous mixture is obtained. The mixing can be done with a normal handmixer, type Festo or Beba.

Monile mortar: put 2 x 25 kg of Quartz 1/4 Arzano and 16.5 kg of Quartz 0/1 Arzano in the mixer and add 6.5 - 7 litres of Monile Liquid. Add 2 x 21 kg Monile Composite (2 bags) and mix till it is homogeneous.The quantity of the Monile Liquid can differ depending on the humidity of the quartz.The use of a Zyclos mixer is recommended to avoid lumps.

Mixing of the Monile components


*RPM/Belgium N.V. - Version 2 - 04.06.2007 - MONILE GBApplicationThe mixing is ready when it looks dry and can be pressed together between the fingers to a compact mass. When being compressed, the mixture should not stick to the fingers. If the mixture is too dry, add Monile Liquid.


*RPM/Belgium N.V. - Version 2 - 04.06.2007 - MONILE GBApplicationApply the mixture on the wet concrete with a hard brush.

Brush lines must stay visible and must not flow together. If brush lines flow together, add some composite to make a drier mixture.

Application of the adhesion layer


*RPM/Belgium N.V. - Version 2 - 04.06.2007 - MONILE GBApplication

NOTE: The concrete must be wet, but there should be no standing water on the floor!


*RPM/Belgium N.V. - Version 2 - 04.06.2007 - MONILE GBApplicationPlace on the floor 2 guides of 13 mm thickness. The distance between the two guides should be 2 meter.

Pour the ready mixture from the wheel barrel into the uncured adhesion layer.

Application of the Monile flooring


*RPM/Belgium N.V. - Version 2 - 04.06.2007 - MONILE GBApplicationDistribute the Monile mixture.

Smooth the mixture with a ruler, as is done with ordinary concrete.


*RPM/Belgium N.V. - Version 2 - 04.06.2007 - MONILE GBApplicationFinish the surface with a powerfloat. Before the treatment, sprinkle some liquid on the surface. This will improve the effect of the powerfloat.

The powerfloat will take the fine aggregates upto the top layer and will close the surface.

In corners where the powerfloat can not be used, use a hand vibrator to obtain the same result.


*RPM/Belgium N.V. - Version 2 - 04.06.2007 - MONILE GBApplication

NOTE: If the temperature is too high during the application or if there is a draught, cover the Monile with Durabran W in order to control moisture content during curing!


*RPM/Belgium N.V. - Version 2 - 04.06.2007 - MONILE GBApplicationThe substrate must be of a porous material: concrete, brick work or similar.

First wet the surface and apply the adhesion layer. For vertical works, the thickness can be decreased to 5-6 mm as there are no mechanical forces of any importance on the vertical parts.

Application of the Monile skirtings


*RPM/Belgium N.V. - Version 2 - 04.06.2007 - MONILE GBWhite spots are a typical effect for cement based systems. They occur when the temperature during application and curing is lower than 12C. This phenomenon is called EFFLORESCENCE.

Explanation:Cement + H2OCa(OH)2 (cured cement)Ca(OH)2 + CO2CaCO3 (white salt)

During the reaction of cement with water, Ca(OH)2 is formed. During this process, H2O is transported to the surface.

Efflorescence / white spots


*RPM/Belgium N.V. - Version 2 - 04.06.2007 - MONILE GBEfflorescence / white spotsThe water is also taking Ca(OH)2 to the surface. At the surface, the water is evaporating and Ca(OH)2 stays at the surface where it can react with the CO2 out of the air to CaCO3 under certain temperature situations. When the temperature is low, the evaporation of H2O is a long process and more Ca(OH)2 shall be transported to the surface.

If CaCO3 is formed at the surface, the Monile floor has white spots on the surface which are visible in dry conditions. If the floor is wet, they are not visible.

Normally they disappear after a few months of intensive use. Chemically, the floor can be etched with an acid to transfer the insoluble CaCO3 into the soluble salt that can be washed away.


*RPM/Belgium N.V. - Version 2 - 04.06.2007 - MONILE GBEfflorescence / white spotsWe recommend the following acids:3% - 3.5% HCI acid solution 3 min. contact time afterwards flush with a lot of clean water10% lactic or citric acid solution 10 min. contact time afterwards flush with a lot of clean waterSee addendum : efflorescence in the Monile Flooring


Subject: Efflorescence in the Monile flooring

From time to time efflorescence can appear on the surface of the new applied Monile floor. This phenomenon, primary efflorescence, is well known and is typical for acrylpolymerisation systems in combination with cement parts. The main factors that are influencing the efflorescence are the application temperature, the draught and the relative humidity. The chemical background is described below.

The cement parts which are present in the mixture of the acrylic dispersion and hydraulic binder are chemically reacting with the water resulting in cement stone Ca(OH)2. This cement stone is water soluble. During the hardening process of the Monile mixture, the water together with the cement stone is transported to the Monile surface. When the water is evaporated the cement stone is remaining at the surface and is reacting with CO2 from the air. The result is the formation of CaCO3 and water. CaCO3 a water insoluble product which can lead to white spots on the surface.

When the Monile is applied at lower temperature, the water evaporation is slower and this allows the cement stone Ca(OH)2 to migrate to the surface where it is built up.

A similar result is obtained in case of strong draught. During the hardening process the evaporation of water is accelerated and gives finally more cement stone of the surface, resulting in white spots.

The white spots, the CaCO3 can be removed by treating the surface with a 10% lactic acid solution. The reaction of CaCO3 with lactic acid is leading to calcium bicarbonate (CaHCO3) which is soluble in water. It is recommended to treat the surface with this solution and this during maximum 10 minutes. Longer exposure times of the Monile floor to this lactic acid can cause slight degradation of the floor. After treatment with this solution the floor is thoroughly rinsed with pure water.

Finally we want to underline that this optical phenomenon has no effect on the quality and functioning of the Monile floors.
