Painting of interior surfaces
RELATED MATERIALS
ISOMAT-CLASSIC – High‑quality emulsion paint for interior use
UNI-PRIMER – Acrylic, water-based primer
DUROCRET – Polymer-modified cement mortar
UNICRET – Mortar for rendering and masonry
UNICRET-FAST – Fast-setting white repairing mortar
STUCCOCRET – Spatula putty
ISOMASTIC-A – Elastoplastic acrylic sealant
I. NATURE OF THE PROBLEM – REQUIREMENTS
Painting walls requires paints that are durable, have excellent bonding to the substrate, good coverage (economical use of material) and provide an easily cleaned final surface.
II. SOLUTION
ISOMAT-COLOR is an ideal solution for painting plaster, concrete, gypsum boards etc. It is a white, water-based plastic paint based on copolymer PVA-VEOVA. It provides:
• Brilliant whiteness.
• Excellent coverage.
• Vapor permeability, allowing the substrate to breathe.
• Excellent bonding to the substrate.
• Excellent washability.
• An aesthetically pleasing finish.
III. APPLICATION
Substrate preparation
1. The surface to be painted must be dry and free of any grease, dust and loose particles.
2. Repair any existing imperfections in the plaster with DUROCRET (polymer-modified mortar), UNICRET (cement‑lime mortar) or UNICRET-FAST (fast-setting cement‑lime mortar).
3. Stucco the surfaces with STUCCOCRET spatula putty.
4. Fill cracks and joints, after widening them to 3 mm, with ISOMASTIC-A plastic-elastic acrylic sealant.
5. Prime the surface with UNI-PRIMER acrylic primer. When the plaster is loose and can be rubbed off, UNI-PRIMER stabilises its surface. Consumption of UNI-PRIMER: 100–200 g/m², depending on the absorptivity of the surface.
6. Once the primer has dried, application of ISOMAT-COLOR can follow.
Application of ISOMAT-COLOR
ISOMAT-COLOR may be used undiluted or diluted with 5‑10% water. Apply 2 coats by brush, roller or spray. Apply the second coat only once the first coat is fully dry. Coverage: 8–10 m²/kg per coat.
