BioRid - Water-borne functional coating

BioRid is a waterborne functional coating containing micropores, which eliminate moisture and keep the surface dry. BioRid is especially suitable for new and previously painted surfaces in conditions where protection of the paint film from mold contamination is required.
Product features
BioRid is suitable for interior painting of walls and ceilings, on substrates of concrete, plaster, bricks, and metal. Application on steel surfaces requires an anti-corrosion primer, to avoid discoloration or yellowing from rusty surfaces.
Recommended uses
BioRid is suitable for new and previously painted surfaces, such as in living facilities, cellars, parking garages, food industries, warehouses, and animal husbandry operations. BioRid is not suitable for unpainted wooden surfaces. Read the application instructions carefully before starting the painting work.

Application conditions
The surface to be coated must be dry, the temperature of the air and surface at least
+5 °C, and the relative humidity of the air below 80 %.
New surfaces:
Remove dirt and dust from the unpainted surfaces. Fill the surfaces
with suitable Presto or Prestonit filler, if needed. Prime porous and
absorbing surfaces with ProSeal before applying BioRid.
Unpainted molded surfaces:
Apply BioWash, diluted with water (mixing ratio 1:2), on mould affected
surfaces with a sponge, smooth brush or spray. Let the solution act for
about 20 minutes. When the surface is still wet, use a brush or high pressure
washer (200 bars) to remove mould. Rinse the surfaces carefully with clean water, from the top to the bottom. Fill cracks and holes with a suitable Presto or Prestonit filler. Apply BioRid on the treated surface within 24 hours. For porous and absorbing surfaces, prime with ProSeal.
Previously painted molded surfaces:
Wash previously painted surfaces with BioWash, see instruction above. Remove loose, flaking paint with a scraper and sand hard,
glossy and industrially painted surfaces matt. Fill cracks and holes with
a suitable Presto or Prestonit filler.
For both unpainted and previously painted molded surfaces, apply BioWash diluted with water (mixing ratio 1:50) over the whole surface for sterilization of the surface. Let the surface dry. Apply BioRid on the treated surface within 24 hours. For porous and absorbing surfaces, prime with ProSeal.
Stir BioRid well before use. The product is ready to use but can be thinned with water, when needed. Apply 1-2 times by brush or roller to desired thickness.
Note! Surfaces coated with BioRid should not be recoated with other paints or coatings, because that would result in the loss of the desired properties.
Cleaning of tools
Remove excess coating from tools, and clean them with water. Tikkurila Tool Cleaner is recommended for removing hardened coating from tools.
Maintenance instructions
Avoid high-pressure cleaning.
Maintenance treatment
Surfaces coated with BioRid should be recoated with the same product if needed, to retain its properties.
