Pore Filler
The Pore Filler is a water-based product specifically designed to prepare surfaces before applying Optimum Varnish.
It ensures excellent adhesion by effectively filling surface pores, providing a smooth base that enhances the varnish's grip and guarantees a flawless finish. This primer is essential for protecting your surfaces while extending the durability of the finishing layers.
When Should I Use a Pore Filler?
- My surface is porous.
- I plan to protect my surface with Optimum Varnish, so I need to apply the Pore Filler first.
- I want to ensure my finishing varnish adheres perfectly.
- I need to prevent moisture infiltration or damage before applying the protective layer.
Application:
The Pore Filler is applied directly to a clean and dry surface using a roller. Once applied, it penetrates the pores to smooth the surface texture. Allow the product to dry fully before applying the varnish to ensure a long-lasting, even finish.
Note: For ISY microcement or varnishes other than Optimum Varnish, the Pore Filler is not required.
For more technical information about the product and its application, download the technical sheet available in the "Product Manuals" section below.
Tips:
- Ensure the surface is completely dry before application.
- Check the surface’s moisture content using a digital hygrometer (maximum 2%).
- If your surface is not porous or still damp, do not use this product. Strictly follow drying times to achieve professional and long-lasting results.
Product Features:
- Type: Single-component primer/pore filler, water-based.
- Consistency: Liquid.
- Color: White; transparent when dry.
- Coverage: 1 L = 10–12 m² in one coat, depending on porosity.
- Storage: 12 months in original unopened packaging, stored in a dry, frost-free environment.
