Description
Our 25 kg rock salt is engineered to melt ice and snow on driveways, car parks and walkways quickly and effectively. As a top choice for rock salt for driveways and pathways, its coarse crystals break down frost on contact, restoring safe, slip-resistant surfaces even when temperatures drop below freezing.
Packaged in robust, easy-lift sacks, this rock salt can be scattered by hand or with a mechanical spreader. Each 25 kg bag will treat approximately 100+ standard car parking spaces at a 20 g/m² spread rate (typical for driveways and parking areas), or around 40-50 spaces when applied heavily for extreme weather. Use it as a preventative treatment before a frost or to tackle settled ice,once the surface has thawed, simply brush away any remaining granules or rinse the area with water to clear residual salt.
- Fast-acting coarse crystals: Break down ice and snow on contact for quick clearance
- Coverage per bag: Treats approx. 100 car parking spaces when applied for moderate weather.
- 100% rock salt: No grit additives.
FAQ
1. What is the effective temperature range for rock salt?
Rock salt melts ice down to around –9 °C. Below this, you may need a blended or alternative de-icer (e.g., calcium chloride).
2. Can rock salt damage concrete or metal?
Prolonged exposure can increase concrete surface scaling and accelerate metal corrosion. Rinse surfaces after thawing and avoid direct contact with structural steel where possible.
3. When should I apply the salt?
Pre-salting: Scatter up to 24 hours before a freeze to prevent ice forming.
Reactive gritting: Apply directly onto snow or ice to break it down.
4. How quickly does it work?
Under typical winter conditions (around -5 °C), ice will start to break up within 10-30 minutes. Actual speed depends on temperature, application rate and crystal size.
5. Is rock salt environmentally friendly?
Sodium chloride can raise soil salinity and harm vegetation if over-applied. Use sparingly, contain runoff, and consider planting salt-tolerant species near treated areas.
6. What’s the shelf life of a 25 kg bag?
When stored dry and covered, it remains effective for several years—the anti-caking additive keeps granules free-flowing.
7. Is it safe for pets and plants?
Rock salt can harm vegetation and irritate paws. Use sparingly near lawns or borders, and rinse runoff areas if necessary.
