Introducing Rapid Set Tru - the self-levelling polished concrete floor overlay - P Mac Dublin

We are very excited at P Mac about the introduction of our latest contemporary flooring solution, Rapid Set Tru® self-levelling polished concrete floor overlay. A bit of a mouthful, we agree! However, this product does exactly what it says on the tin. This modern flooring solution allows you to have an attractive, hard-wearing and contemporary polished concrete floor within days, from start to finish! It is the perfect solution for fit-outs and retro renovations.

Fast high-quality concrete flooring with Rapid Set Tru®

Rapid Set Tru® is the answer when time is a constraint and you don’t have the option to lay a 75 mm concrete slab (which is the minimum requirement for a polished concrete floor). It provides you with a beautiful, strong and enduring polished concrete floor in only a few days. With a classic polished concrete floor, you need a minimum of 4 weeks curing time before you can grind and polish. However, with Rapid Set Tru® you’re good to go after only one day.

How does Rapid Set Tru® work?

With Rapid Set Tru®, the concrete screed is made up of advanced hydraulic cement-based, self-levelling topping resurfacer and underlayment. It can be used both indoors and outdoors. As a self-levelling screed, it finds its own level which guarantees a smooth, even and strong surface. It remains workable for 20 minutes, so time is of the essence! The minimum thickness we recommend is to bring up your level to 7 mm and to a maximum thickness of 12 mm. If you require more depth than this, for cost implications, we recommend bringing your floor up to the desired level with a regular self-levelling screed first.



Keeping that in mind, the substrate or sub-floor has to be in fairly good shape. The substrate must be even, solid and load-bearing. Any pipes must be buried and covered. Before application, the substrate must be swept clean of any contaminants or rubble. Another reason for burying your pipes is to avoid any heat inconsistencies in the sub-floor because this can leave tracks on your finished polished floor. Like a classic polished concrete floor, Rapid Set Tru® is ideal for underfloor heating and the same rules apply. Once cured, make sure to turn on your underfloor heating very gradually over two weeks.

Expansion joints need to be inserted every 36 m2 to help prevent cracking. If there are expansion joints in the subfloor, these must be mirrored on the finished floor. Due to the short working time of the mix, your floor will be laid in one day. The curing time is extremely fast and reaches a strength of 20 N in just 4 hours, rendering your floor ready for foot traffic after 4 hours. After 24 hours, the floor reaches a strength of 45 N and is now ready for grinding and polishing. In fact, it must be polished the following day as the longer it is left the stronger it becomes and after 3 days it will be too hard to polish.

Installing Rapid Set Tru

On day 2, the floor is ground and polished to bring it up to a stunning, smooth and durable high shine finish. Additives and colours can be added to change the appearance of the finished floor. If you desire a more Terrazzo like finish, your chosen aggregate can be added to the mix. Rapid Set Tru® comes in a selection of colours and additional dyes can be added at the pour stage to give you the desired finish. It is ideal for embedding logos and designs into your floor! You could really let your imagination run wild if you’ve got the budget.


The advantages of using Rapid Set Tru®


Rapid Set Tru® is very comparable in price to a stone or solid wood floor. Your Rapid Set Tru® floor is a floor for life and it doesn’t require cyclical maintenance costs. It provides you with a continuous smooth finish which means there are no nasty grout joints to keep clean!


Rapid Set Tru® is suitable for indoor and outdoor use. It is also ideal for bathrooms and wet rooms. We would advise applying an anti-slip coating if a lot of water will be present. However, Rapid Set Tru® is only suitable for horizontal surfaces, as it is self-levelling it will not work on steps or upright surfaces. You would need to consider Microtopping if this is required, or a combination of both looks really well.


Rapid Set Tru® is an extremely hard-wearing and durable flooring solution. The finished floor is sealed with a penetrating seal which heightens its resistance to staining. A Rapid Set Tru® floor is maintained the same way as a stone or polished concrete floor. Regular cleaning with pH-neutral soap and the installation of entrance mats will keep it in tip-top shape. The beauty of a concrete or stone floor is, of course, that it can be revived and brought back to new every few years if it begins to lacklustre.


As we’ve already explained, Rapid Set Tru® is able to provide you with a super-fast polished concrete floor after just one day! In this respect, Rapid Set Tru® far exceeds the classic polished concrete floor.
