School roofing: Waterproof and spraying of Alberview Primary.

Alberton / Johannesburg South

Core Features: Before

Waterproofing and spraying acrylic roof paint on Chromadek sheets is a common practice to protect the metal sheets from corrosion, UV radiation, and water damage. Chromadek is a pre-painted steel sheeting that has been galvanized and coated with a layer of paint for durability.

Preparing the roof surface

Before applying the acrylic roof paint, it is important to ensure that the Chromadek sheets are clean and dry. Any dirt, dust, or debris on the surface can compromise the adhesion of the paint and lead to uneven coverage or premature wear.

Core Features: After

Once the Chromadek sheets are clean and dry, a primer may be applied to help the acrylic roof paint adhere properly. The primer should be compatible with both the Chromadek substrate and the acrylic roof paint.

Next, the acrylic roof paint can be sprayed onto the Chromadek sheets using a paint sprayer. It is important to follow the manufacturer’s instructions for the acrylic roof paint, including the recommended application rate and drying time. Typically, several thin coats of paint are applied to ensure complete coverage and a smooth, even finish.

Waterproofing is an important step in protecting the Chromadek sheets from water damage. A waterproofing agent can be applied to the surface of the sheets before the acrylic roof paint is applied, or a waterproofing layer can be added as a separate step after the paint has dried.

Overall, waterproofing and spraying acrylic roof paint on Chromadek sheets can help to extend the life of the metal sheets and protect them from damage. It is important to use high-quality products and follow proper application techniques to ensure the best possible results.
