Why Use Cement Boards Outdoors?
Natural weather conditions will put materials under pressure. Rain, temperature changes and sunlight will make significant change in their structure. Cement boards can face it all with strength and stability.
What are the key benefits for using cement boards outdoors?
At Tilejob the first thing we have to mention here is that there are two types of cement boards: interior and exterior use. The exterior ones have special features which make them reliable for outdoor:
- Water resistant – does not absorb water and cause swelling
- Frost resistant – suitable for high level of moisture and frosty conditions
- High strength – can create a good base for outdoor tiles
- Stable surface - minimises the movement and helps to avoid cracking for tiles and grout
- Long lifespan – a perfect material which is a long term investment.
Where Can Cement Boards Be Used for Outdoor areas?
Outdoor cement boards are very versatile material which you can use with nearly any project:
To build Patios and terraces
To build Outdoor kitchens and BBQ areas
To build Balconies and raised platforms
To build Garden walls and cladding
To build Steps and entrances
All these projects require specific resilience and flexibility which can be achieved with cement boards.
How to Choose the Right Thickness?
Our experts at Tilejob will recomend for a smooth and accurate finish to choose the suitable thickness.
- 6mm boards – will work for walls and light applications
- 10mm / 12mm boards – suitable for floors and heavy-duty outdoor use
Note that for extra resilience of the flooring projects, 12mm cement boards are a must option due strength and rigidity conditions being required.
