This spray features a silicone-based formula that helps reduce friction on metal, plastic, and rubber parts. It dries quickly and resists moisture, extending the working life of equipment in wet or high-pressure settings.

Who This Product Is For

This silicone spray is designed for maintenance professionals, automotive technicians, and serious DIY users who need reliable lubrication and protection for mechanical components. It suits those working with equipment that requires regular maintenance in demanding conditions.

The product is appropriate for workshop environments, automotive repair settings, and domestic maintenance tasks where friction reduction and moisture protection are needed on metal, plastic, and rubber components.

Key Features

• Smart Straw Applicator: Switch from a focused stream to a broader spray for wide coverage or precise aiming.
• Clear Formula: Leaves no residue or marks on surfaces, so parts stay tidy and free of gunky build-up.
• Moisture-Resistant: Repels water and helps prevent rust on metal fittings and hinges.
• High Temperature Range: Works from -35°C up to +200°C, so it handles tough environments.
• Quick-Drying Action: Reduces downtime by setting fast, which speeds up maintenance tasks.

Key Benefits

• Lowers friction to extend equipment life.
• Minimises squeaking noises in automotive or household fittings.
• It blocks moisture in wet locations and protects vulnerable parts.
• Works effectively on rubber, plastic, and metal in varied situations.

Practical Applications

This product is suitable for lubricating squeaky hinges and conditioning rubber seals on car doors. It also helps reduce friction in sliding windows and defends garden tools from damp conditions. The clear layer it forms stops residue build-up, which benefits many workshop tasks.

Before using silicone spray on electrical switches or connectors, clean contacts with a fast-drying electrical contact cleaner.

How This Fits Into a Typical Job

This silicone spray is typically used during the maintenance and preparation phase of a job. After cleaning surfaces and before putting equipment back into service, the spray is applied to provide lubrication and protection. It fits into a system where components need regular conditioning to maintain smooth operation and prevent corrosion.

The product works as part of a maintenance routine where surfaces are cleaned first, then treated with silicone spray, and allowed to dry before equipment is reassembled or returned to use.

How to Use

1. Clean the Surface: Wipe away dust or grease using a degreaser so the spray makes direct contact.
2. Shake the Can: Agitate well for a consistent blend.
3. Choose Your Spray Mode: Flip the straw up for pinpoint aim, or keep it down for broader coverage.
4. Apply in Short Bursts: Aim at the target area, holding the can a few centimetres away.
5. Wait Briefly: Allow a few minutes for the film to settle before using the equipment.

Not Suitable For

• Electrical contacts or switches without prior cleaning with appropriate contact cleaner
• Applications where food contact is involved
• Surfaces that require paint adhesion (as silicone may interfere with bonding)
• High-load bearing applications where specialised lubricants are required

Storage and Maintenance Tips

• Keep it in a cool, dry place to avoid heat exposure.
• Wipe the nozzle after each use to stop clogging.
• Check the expiry date on the can to maintain product performance.
