Masonry
Sissons Masonry Paint is a specially formulated low-VOC, decorative wall finish which is suitable for interior cement plaster walls, ceilings, hard and soft boards and other cementitous-based surfaces. It is easy to apply and when dry, presents a pleasing matt finish with good opacity that is durable and fungus resistant.
Surface
Surface preparation should be properly carried out before application. All loose, flaking, chalking or friable materials should be removed. Make good any defects and ensure that the substrate is clean and free from contaminants, such as oil, grease, grime and fungal growth.
For new surfaces, ensure that the substrate is sufficiently dry (below 16% moisture) prior to paint application.
For redecoration, ensure that the previous coating is in good condition, otherwise remove via water-jet and/or scraping then treat as per new surface.
New Surface
| Primer | 1 coat of Sissons Alkali Resisting D’Primer |
| Finish | 2 coats of Sissons Masonry Paint |
Redecoration
| Primer | 1 coat of Sissons Basecoat Sealer or Sissons Alkali Resisting D’Primer |
| Finish | 2 coats of Sissons Masonry Paint |
If the substrate colour is uneven, or in the case of re-decoration there is a radical change in colour, an additional coat of finishing may be required
Coverage
| Theoretical Coverage | 11.5 square meters per litre per coat |

8.6 square meters per litre per coat |
Actual spreading rate will vary due to factors such as method and condition of application e.g. surface profile or roughness.
