Composition
Extremely fine acrylic resin dispersion
Properties
This product is flexible, colourless and thinnable with water. It is fully lightfast and age resistant and features excellent penetration into the surface being sealed. It contains no solvents or softeners.
Applications
• for sizing or preparing substrates ranging from moderately porous concrete to highly absorbent sand plaster before applying acrylic colours or dispersion paint.
• in restoration, Hydro-Sealer can also be used for consolidation of paint layers, above all of oil paintings
Directions
The strengthening effect depends on the type of binder used in the substrate. Penetration power is also affected by the absorbency of the surface. Thinning: as an indicative value, mix about one part Hydro-Sealer with 4 parts water. The important thing is that the solution must soak into the substrate without forming a closed film on the surface. Small amounts of Studio Colours can be added to the mixture to identify areas that have been primed.
To consolidate paint layers on oil paintings, Lascaux Hydro-Sealer should be diluted with water in a ratio of 1:1 to 1:4 depending on the desired adhesion and then soaked into the tears, cracks or cuppings. Excess amount of Lascaux Hydro-Sealer on the surface should be removed carefully before drying with a humid sponge or a cotton swab. Lascaux Hydro-Sealer should not be used below the temperature of +5°C (+41°F).
Coverage
Approx. 20-30 ml/m2 per coat depending on the support and application.
