How to prevent spalling in concrete outdoor ottomans exposed to deicers?

Concrete outdoor ottomans are durable and stylish, but exposure to deicers can lead to spalling—a common issue where the surface flakes or chips away. To prevent this, follow these steps:

1. Use High-Quality Concrete: Opt for a mix with low permeability and high strength, such as those containing air-entraining agents to resist freeze-thaw cycles.

2. Apply a Sealer: A penetrating or film-forming sealer creates a protective barrier against deicer chemicals and moisture infiltration. Reapply every 1-2 years for best results.

3. Choose Deicer-Resistant Materials: Avoid chloride-based deicers like rock salt. Instead, use calcium magnesium acetate (CMA) or sand for traction.

4. Proper Curing: Ensure the concrete cures slowly and evenly for at least 7 days to enhance its density and resistance to spalling.

5. Regular Maintenance: Clean the ottoman regularly to remove deicer residues and inspect for early signs of damage.

By implementing these measures, you can extend the lifespan of your concrete outdoor ottomans and keep them looking pristine despite harsh winter conditions.
