Where ACTFLEX 747 TC is used
Use it for
- UV top coat over ACTFLEX 737 PU and other FORSPEC polyurea coatings
- Exposed concrete roofs and roof decks
- Metal and colour-steel tile roofing
- Podiums, balconies, walkways and plant decks left exposed
- Floor top coat: garages, workshops, warehouses and showrooms
- Water storage and sewage tanks and treatment structures, not potable
Know before you start
- Not for potable water contact
- Not straight onto a bare surface: prime first with ACTFLEX 727 SEP
- Not below 5°C or above 35°C, in rain, or in the evening or overnight in winter
- Not over silicone, bitumen or coatings that are not sound and fully bonded
How to apply ACTFLEX 747 TC
- 01
Prepare
Surface flat, hard, dry and clean. Concrete cured 28 days, ground or captive-blasted to an open profile and vacuumed. Render and screed cured 7 days. Abrade and degrease metal and existing coatings.
- 02
Prime
Over ACTFLEX 737 PU inside its 12 hour overcoat window, no primer. Everywhere else, and beyond that window, prime with ACTFLEX 727 SEP at 0.3–0.35 kg/m² and top coat within 24 hours of full dry.
- 03
Mix
Weigh Part A and Part B at 1 : 1 by weight. Mix by machine at low speed until uniform, scraping the sides and base. High speed traps air and causes pinholes. Use within 30 to 40 minutes.
- 04
First coat
Brush, roll or spray at 0.30 to 0.40 kg/m². Lay it off in one direction with full, even coverage and no misses, runs or ponding.
- 05
Second coat
Once the first coat is tack free, 2 to 3 hours at 25°C and 50% RH, lay the second coat off at right angles to the first. Total dry film is 0.4 to 0.5 mm.
- 06
Cure
Light foot traffic 24 hours after the final coat. Full cure and full performance take 4 to 7 days, longer below 10°C. Water immersion only after full cure.

ACTFLEX 747 TC questions
Is ACTFLEX 747 TC a roof or a floor top coat?
Both. It is the UV top coat over FORSPEC polyurea roof and deck systems, and a colour-stable top coat for floors such as garages, workshops, warehouses and showrooms, over primed concrete or a sound FORSPEC floor coating.
How much do I need?
Allow 0.30 to 0.40 kg/m² per coat, in two coats. In practice a 40 kg set covers 45 m² at 0.40, 51 m² at 0.35 and 60 m² at 0.30 kg/m² per coat, with 10% allowed for wastage. The 0.4 to 0.5 mm dry film is what counts.
Do I need a primer?
Not over ACTFLEX 737 PU inside its 12 hour overcoat window. On concrete, render, masonry, metal and sound existing coatings, or once that window has passed, prime with ACTFLEX 727 SEP first.
How long between coats, and when can I walk on it?
Recoat after 2 to 3 hours at 25°C and 50% RH, once the first coat is tack free, so both coats go on the same day. Light foot traffic is 24 hours after the final coat. Full cure is 4 to 7 days.
Is it UV stable?
Yes. It is an aliphatic polyaspartic made for permanent exposure. After 1500 hours of accelerated weathering it recorded powdering level 0 and discolouration level 1, with no blistering and no cracking. Typical FORSPEC R&D values.
How long does it keep?
Shelf life is 6 months unopened, shorter than the rest of the range, so order to the programme. It may crystallise in cold storage. Warm the drums with heating belts until uniform, never by direct flame.
