Car-park decks face tyre wear, oil, water and, on the open top deck, sun and monsoon rain. A crack-bridging resin system with a UV-resistant seal coat and sealed joints protects the slab and the floors below.
General guidance based on the manufacturer data sheets. Site conditions differ: confirm the system with MCT before you start. Where we do not name a product, ask us and we will confirm the right one.

Use a UV-resistant seal coat: Sikafloor-359 SG is UV resistant and non-yellowing (p.1). Sikafloor-3240 on its own can change colour under UV and weathering (p.3).
Sikafloor-3240 takes light traffic after about 2 days at +20 °C (p.3); Sikafloor-18 Pronto reaches full cure in about 1 hour at +20 °C (p.3). Total closure depends on repairs. Ask us: it depends on site conditions.
Sikafloor-359 SG is watertight and is used over crack-bridging broadcast systems (p.1), and the joints must be sealed as well (Sikaflex PRO-3 p.1). Active cracks and joints are assessed first.
Sikafloor-3240 is not for slopes over 1 % (p.3). Ask us: it depends on site conditions.
