MetaClear is a strong alkali gel, containing sodium hypochlorite, used for controlled cleaning of dark black fungal staining discolorations on render and masonry. MetaClear is formulated as a high adhesion gel with viscose properties to stay where applied on vertical surfaces.
- It does not penetrate render porosity and is active where needed - at the surface.
- The gel prevents evaporation.
- Stabilises the active surface concentration throughout the process.
- Provides dwell time. This in turn gives a new flexibility in the sequencing of the works, particularly when applying from an aerial platform.
- The gel lubricates the surface when brushed, limiting the risk of scuffing on powdery surfaces.
- It is low odour and rinses readily.
Application on render and masonry work
- Surface preparation: If the initial biofilm is thick and long established, reduce its mass by brushing with a light solution of Algoclear Pro followed by rinsing or steaming.
- On self-coloured render, if fungal metabolites are prominent over large areas, use Metaclear as the primary treatment. An application of Algoclear can follow if algal discolouration remain.
- For renders where algal discolourations are dominant, use Metaclear after the algal biofilm has been treated with Algoclear. Apply on a dry surface.
Application on window sills, cornices and in particular wall copings
The metabolites are best removed by brush. The coverage decreases to 3 to 4 m2 per litre. If sprayed, leave to dwell 10 to 15 minutes and agitate with a soft brush to renew the active interface if the layer is deep. Leave to dwell long enough to have the desired effects and collect with a squeegee and/or rinse. Renew the application if necessary.
Notes
- Substrate moisture should be generally dry
- Not intended as a surface biocide
- Avoid release in the environment
- Keep in a dry ventilated place (between 5°C and 30°C)
- If applying through sprayer, take a look at our Disinfector High Pressure Pump Sprayer
- Storage: 6 months following the production date when kept in the original unopened container
- We suggest only ordering enough product for medium-short term usage as any sodium hypochlorite can deteriorate over time, but gel formulations change at a slower rate than liquid formulations
