A professional roller with thick nylon spikes, 21 mm or 31 mm long, designed for deaerating self-leveling mineral and resin screeds. The roller is wide (50 cm / 20") and solidly constructed. It has a metal handle for a telescopic shaft/stick with a diameter of 25 mm. The roller is also equipped with a special plastic protective cover that prevents walls from getting dirty.
The length of the spikes is selected based on the thickness of the poured floors. Resin floors are usually applied in thinner layers, where 21 mm rollers can be used. Cement floors are often poured in thicknesses of up to 30 mm, where a roller with 31 mm spikes will be useful.
