Description
Is this the right product?
Use it for: Polishable, self-levelling cement topping for professional concrete polishers: a thin, very dense, hard and durable resurfacing layer for indoor floors in light industrial, commercial, retail and residential spaces, including light vehicle traffic. Fine with occasional water. Goes over new (28-day cured) or existing sound concrete. 1/2" to 2" (12 to 50 mm) neat, or up to 5" (125 mm) extended with pea gravel. Polish in as soon as 24 hours; it can typically be stained, sealed or coated after 24 hours. The concrete needs a CSP 3 profile and a coat of Primer SN with a full sand broadcast first.
Not for: Do-it-yourself jobs: Mapei says it is for professional concrete polishers only, and a sizeable mock-up is required first. Outdoors, chemical environments, heavy manufacturing, or steel-wheeled and hard, small-wheeled traffic. Unrepaired cracks and joints will show through, so joints must be carried up through the topping. Slabs over 5 lbs MVER need a Mapei moisture barrier first. Use between 10°C and 32°C and keep it there for 72 hours; no rolling loads for 48 hours.
Use instead: Levelling a floor that will be covered with flooring: Ultraplan 1 Plus. Resurfacing worn concrete inside or out: Concrete Renew.
Want a polished concrete floor over an existing slab? Ultratop PC is a self-levelling, cement-based topping engineered to be extremely dense, hard and durable, and it can be polished in as little as 24 hours. Pour it 1/2" to 2" thick neat, or up to 5" extended with pea gravel.
It goes over new (28-day cured) or existing sound concrete in homes, shops, retail and light industrial spaces, and takes light vehicle traffic. The concrete must be ground to CSP 3 and primed with Primer SN with a full sand broadcast; Mapei does not warrant Ultratop PC without it.
22.7 kg (50 lb) bag · Coverage: about 10.6 sq ft at 1/2" · Polish in 24 hours · Indoor use
For professional concrete polishers only, per Mapei. Plan a sizeable mock-up before the full pour.
