A Spiked Roller must be used on newly laid concrete screeds to release trapped air bubbles from curing on the surface. If a Spiked Roller is not used, air bubbles will form on the surface and will ruin the appearance of the smooth concrete. It may also cause lifting or cracking when trafficked by vehicles or forklifts.

Don’t spike roller for more than a maximum of 20 minutes (less on very warm days) as by then the Pourable Concrete Leveller would have started to dry and you’ll be left with spike roller marks.
