Coverage: One set (decobase + Polaris effect) is sufficient to cover approximately 7m² of a wall's surface. Step-by-step application: The substrate should be clean, degreased, even, stable and uncracked. Surfaces that are highly absorbent (e.g. fresh plaster), or those that are not equally absorbent, should first be primed with a suitable primer. We recommend our PRIMACOL DECORATIVE primer, which is a universal product and will work for most surfaces. First step: DECOBASE Paint the surface with Decobase paint. It will create a base coat similar to the effect's colour, reduce the consumption of Polaris and ensure the best possible final result. When dry, sand the wall gently with fine sandpaper and dust it off afterwards. Second step: POLARIS After opening the Polaris bucket, stir the contents thoroughly. Start applying the product from the top corner of the wall and move diagonally extending the decorated surface. Apply the product with a venetian trowel, spreading it in different directions. Work on small areas at a time using the "wet-on-wet" method. The thickness of the applied layer should not exceed 1 mm. If you find it necessary, you can apply a second coat of paint, also starting from the top of the wall, but from the opposite corner. Before the surface dries completely, smooth it with the edge of a clean venetian trowel in different directions. This will emphasise the Polaris effect, especially the satin reflections. Repeat the process until the desired decorative effect is achieved and leave the wall for at least 24 hours until completely dry. Decobase primer and Polaris decorative effect are sold separately: To achieve the best decorative result, use the Decobase primer first, followed by the Polaris effect., Manufacturer: PRIMACOL
