To limit your roof tiles from damage, leaks and for just maintaining the aesthetics of the roof in general we recommend that you seal your concrete roof.
To seal your concrete roof tiles, you will need;
- Acrylic masonry surface cleaner
- Airless spray system
- Ladder
- Paintbrush
You need to fill the spray system’s reservoir with acrylic masonry surface cleaner and then connect the system to nearest electrical socket. You may need an extension due to the distance between your electric socket and roof. Start spraying at the top edge from one side of the roof, spraying the sealer in a calm motion. Move downwards and make sure that the spraying overlaps the edge of the already sprayed area. Once the whole roof is done, allow the sealer to dry for a minimum of two hours. If the sealer is dry, apply another coating of sealer and then wait again till dry.
