PELICOAT PRO ROC
Hardener of surface mono-component
Nature : silicate ethyl in phase solvent aliphatic, aromatic and nonaromatic
Application : hardener of all types of absorbing and porous stones, bricks, concretes and mortars cement. Allows the consolidation of these matters while keeping porosity as well as the water vapor transmission.
Properties Characteristics
- Particularly effective before proofing.
- high Penetration.
- No film formation.
- Lets breathe the support.
- Excel ageing.
- the esthetics of the support does not modify
- the treated support can be waterproofed or painted - ethyl Silicate : 50 %
- Solvents : 50 %
- dry Extracts : +/- 33 %
- Density : 0.90
- Not flash : + 40 C
- Aspect : Colourless slightly yellowish
Application
Depends on the degree of deterioration of the building machinery. We can give you some councils in order to obtain a satisfactory result:
To determine:
- solidity, capillarity, rock salt, etc…
- an average consumption
- To check that there is no change of color
- To check adherence
- To carry out the final tests of effectiveness.¶
Working conditions:
- to clean surfaces Well to be treated
- If the materials became too friable, to make a pretreatment in order to be able to clean
- the materials must be dry or avoid the rain during 2 or 3 days
- It is recommended to avoid the direct light of the sun, which could cause a too fast draining.¶
- the ideal temperature lies between 10 and 20 C.
Methods of application
All the methods are good taking account of surface to treat.
- Quantities : most significant is to prevent that a crust is not formed. To initially try to treat a brick at the same time. It is necessary, if necessary, to repeat the operation after 2 or 3 weeks because it is absolutely necessary to obtain a complete saturation. If, between the two layers, the active formation is not obtained, the second layer will become gray.
- the quantity necessary is 0.5 to 15 liters with m2.
(Example : for a brick become friable with a 6 cm depth, the 1st treatment will be 5 L/m2 and 3.5 L/m2 after 3 weeks).
- In other cases, 2.7 L/m2 were employed for walls having a friability of more than 10 cm.
After treatment
It can prove to be useful to clean surface with white spirit to avoid a discolouration.
Safety Storage
- not to put in contact with food
- to ventilate Well. Slightly flammable product, prohibition to smoke during work is formal
- To put safety goggles
- To protect the plastics (example : bumpers of cars). - Approximately 12 months in its packing of origin.
- the product fears freezing.
