IsoSil

Water based siloxane clear sealer.

General Features:

ISOSIL and ISOSIL color are water based sealers formulated with special siloxane resins. They have a high penetration and isolation power and do not alter in any way the permeability rate of the substrate.

Texture:

ISOSIL: transparent liquid.
ISOSIL color: white or pigmented liquid.

Uses:

  • Over mineral substrates such as reinforced concrete, plasters and old lime paints.
  • Over preexisting paints or synthetic plasters in good condition.
  • Priming coat of the siloxane paints - Novasil, Novasil Quartz and Novasil Velour and of the siloxane coating Rustiksil.
  • Primer for lime base finishes. (Must be mixed with ERA lime paint.)

Substrate Preparation:

The substrate must be perfectly dry, dust-free, with no humidity and salt stains. In most cases a light brushing off would do. Non-adhering preexisting paints must be removed with a paint remover containing no paraffin, or with a high-pressure washing treatment.

Application Procedure & Recommendation:

ISOSIL used as priming coat of the siloxane paints and plaster coats Novasil, Novasil Quartz, Novasil Velour and Rustiksil: dilute 1:4 with water, depending on substrate absorption.

ISOSIL used as priming coat of the lime finishes Era and Marmur: mix in the same proportion with ERA lime paint; then add water in a 1:1 or 1:3 ratio, depending on substrate absorption.

ISOSIL color, used as priming coat of the siloxane paints and plasters Novasil, Novasil Quartz, Novasil Velour and Rustiksil: dilute with 40-50% of water, depending on substrate absorption.

Make a test first, in order to check that the substrate does not get any "glossy" reflections after the treatment with Isosil. If this should be the case, increase the water dilution rate. The best results are achieved when the product is applied with a brush, working from the top to the bottom. Roller or spray gun applications are possible too. Do not apply with rainy weather or with air or substrate temperature below 5° C.

Yield:

ISOSIL: 7-20mq/lt, depending on substrate absorption.
ISOSIL color: 3-6mq/lt, depending on substrate absorption.

Specific Weight:

ISOSIL: 1,029 kg per dmc.
ISOSIL color: 1,440 kg per dmc.

Color Range:

ISOSIL: Transparent.
ISOSIL color: white and custom colors.

Packaging & Shelf Life:

ISOSIL 5 - 15 lt pails.
ISOSIL color: 15 lt pails:
The packaged products, if stored at temperatures between +5 and 35°C, are guaranteed for 12 months.

Specification:

Prior to the application of a siloxane finishing coat, and after adequate substrate preparation, (i.e. after removal of any non-adhering preexisting paints with a paint remover containing no paraffin or with a high-pressure washing treatment), apply ISOSIL (or ISOSIL color) water based siloxane sealer.

Prior to the application of any lime finish: apply one priming coat of ISOSIL (or ISOSIL color) , after adequate substrate preparation, i.e. after removal of any non-adhering preexisting paints with a paint remover containing no paraffin or with a high-pressure washing treatment. ISOSIL (or ISOSIL color) shall be mixed in equal parts with Era lime paint and then further diluted with water, according to the manufacturer's instructions and at any rate trying to avoid a glossy finish. Apply the product with a brush, working from the top until the bottom of the wall.

Warning:

Dispose of the empty packaging and remaining material in compliance with local laws.
