Complexon paste has been developed to safely remove lime scale, heavy soot deposits, nicotine and grime from almost any building material without leaving or generating harmful salts. These surfaces include ceilings, floors, plasterwork, natural and artificial stone, brick, etc. where the substrate is in good order.
Metal compounds e.g. rust or copper oxidation which have not penetrated deep into the surface can be removed.
Application:
Complexon paste is not suitable for absorbent materials (e.g. textiles, paper, fibrous wood or surfaces which are water coloured (where the colours are to be retained).
It is important that the Complexon paste is applied to the pollution only and not to any clean surface as it is possible that certain sensitive surfaces may be adversely affected (e.g. marble where the polish may be removed). Similarly some fine surface loss may occur in calcareous bonded stone.
On each new application carry out a small trial sample, particularly if the substrate is covered in a very loose (powdered) lime paint as the pigmentation may be affected. Also check with a microscope that the cleaned surface is acceptable.
NB. The speed of drying is affected by surrounding temperature, which should ideally be 15°C. Even under plastic cling film the drying out process is accelerated above this temperature.
If freezing takes place the paste will disintegrate. Do not use if there is a change in the consistency of the paste.
Storage:
Store the Complexon paste in a cool room (though above freezing). Try to avoid keeping partly used containers. Do not leave metal objects in the paste as this will leave a stain which will subsequently affect surfaces to be cleaned. Keep the packaging firmly closed (not just resting the lid) when not in use. Do not dilute the paste either with solvents or water. If the paste has thickened it may be possible to use limited water to recover the original consistency.
Instructions for use:
1. EXTERIOR SURFACES:
Attempt a small test area first.
Beware of loose or friable surfaces which may be disturbed when Complexon paste is removed.
Apply the Complexon paste with a soft brush, spatula or artificial sponge to a depth of 2-5 m. Cover the paste with plastic cling to prevent drying out. The cling film should be removed after two or three days. The paste is washed away with hot water (which can be made easier with the use of a nylon bristle brush). Repeat if necessary.
Light rain on the applied paste is not a problem but heavy rain could wash away the active ingredients in the paste, creating a residue. Once the cling film is applied this problem is reduced.
2. INTERIOR SURFACES (WHEN WATER CANNOT BE USED FREELY):
Attempt a small test area first.
Apply the Complexon paste in a layer of 2-3 mm. Cover this with a fibrous felt material. Leave for one of two days (depending upon the temperature, which should be at approximately 15°C). Peel off the felt, together with the paste. If a corner is covered with a piece of cling film this may assist the peeling off but this will restrict the drying out.
Clean off residue using minimal amount of water. Repeat if necessary.
Tool Maintenance:
If tools do not contain metal parts they can be left for short periods in the covered packaging. All the paste components are biodegradable, inert and will not pollute the environment. They can, therefore, be safely washed away.
Safety:
See Safety Data Sheet before using Complexon paste. It is suggested that the usual safety glasses and other protective clothing be worn.
