Step Safe Heavy Duty spray resin in Sydney

Step Safe Heavy Duty is the Shieldcoat system I call spray resin: a flexible acrylic resin you spray over existing concrete. It gives a textured, P5 anti slip finish in almost any colour, and it’s on the shelf at our Wetherill Park warehouse in 10L pails.

Where do you use Step Safe Heavy Duty?

Driveways, footpaths, patios and pool surrounds, on concrete that’s at least 28 days old. It’s flexible, so when a slab moves it moves with it instead of cracking like the rigid coatings do. That’s why it lives outside, while epoxy still has its place inside the garage. More on that in spray resin vs epoxy vs spray crete.

Shieldcoat backs it with a 7 year manufacturer’s warranty against cracking, flaking and peeling. It’s fade proof, floors last 20 to 25 years, and it needs a touch up every 6 years.

How the system goes down

1. Prep. Pressure clean, or grind where the surface needs it. The slab must be at least 28 days old and under 6% moisture. No exceptions.
2. Repair. Fill cracks with Slab Repair.
3. Prime. Roll on Primer X, or Step Safe WB Primer over water based coatings.
4. Spray. Two base coats of Step Safe Heavy Duty through a hopper gun, then two fleck coats.
5. Seal. Two very thin coats of Concreshield Clear Low Sheen, always on a later day, never the same day.

Foot traffic is fine after 24 hours. Give it 7 to 10 days before a car goes on it, with no turning the wheels on the spot for 4 weeks, and full cure takes 28 days. Pavers only get coated when they sit on a concrete base (grind, pressure clean, then Primer X). Pavers on sand and outdoor tiles never do.

Install tips from the job

• Run the OX hopper gun with the 6mm tip off a compressor with at least a 100L tank. A small tank gives you inconsistent pressure and a patchy finish.
• First coat at 28 to 30psi on the inline regulator, sprayed from hip height in a circular motion, aiming for 80 to 90% coverage.
• Second coat at 23 to 25psi, thin. Too much product leaves glossy patches. If it happens, let it dry, then lightly mist to bring the texture back.
• Fleck at 5 to 10psi from chest height. The fleck colour you want to see most goes on last.
• Cold concrete slows drying far more than cold air. Use airflow or the accelerator in slow drying areas.
