SSR Flow Screed

Liquid Screeds

There are many benefits when it comes to using liquid screed instead of the more traditional sand and cement screed. These advantages apply in particular to its use with underfloor heating.

Benefits of liquid screed

  • Fast application
  • Reduced labour costs
  • Superb Thermal conductivity and retention
  • Level floors

Why choose our liquid screed?

Our screeds are very popular in both commercial and residential applications. Utilising our fast delivery system, our screeds can cover 1000 square metres every day, thus, avoiding very substantial labour costs and other issues that can arise, such as wheelbarrow damage to heating pipework and door frames.

Underfloor Heating

Underfloor heating may seem overly luxurious for many households and budgets and it can be a messy, difficult thing to install, however, there is no doubt that it is an effective alternative to traditional radiators or hot air heating systems, especially in rooms with traditionally cold floors made of stone or tile, so, if price is a factor for you it can be surprisingly affordable, especially if you are renovating.

Benefits of underfloor heating screed:

  • Lower energy bills
  • Lower running temperature, thus, reducing wear and tear on your boiler
  • Superb thermal conductivity and retention
  • Screed systems are versatile and green
  • No space hogging radiators
  • Natural, consistent heat flow from floor to ceiling
  • Lowered risks of dust mites
  • Heat is far easier to control

Laitance Removal

Laitance removal is essential with most floor screeds. Laitance is a weak, flaky layer that forms on the surface a few weeks after pouring. It can cause imperfections and problems for flooring contractors due to bad adhesion of new flooring products.

Laitance Removal should ideally be carried out whilst the screed is in the drying process, this minimises dust and mess.

SSR can sand your floors, simply ask for it to be added to your quotation.

Q: Can I still use flowing screed without underfloor heating?

A: Yes, flow screed is the best method to achieve a level floor

Q: Do all screeds need to be sanded and have laitance removed?

A: No, generally only gypsol flowing screeds require laitance removal.

Q: Do I HAVE to have insulation under the screed?

A: This is down to personal preference, if you have underfloor heating installed, then definitely yes. SSR will not screed over underfloor heating without insulation in place.

Q: Can you create an incline with floor screed?

A: Absolutely not, screed in its nature tries to level itself.

Q: Can you install screed in my car garage/port

A: We have a cement based screed available that can also be used with steel re-enforcements without reacting. We will not use anything that isn’t concrete based on garage floors.

Q: Do I have to use expansion edging?

A: Yes, the floor needs room to move, especially underneath your floor covering.

Q: Can I use anything other that damp proof membrane to lay over the floor?

A: No, 1000 gauge membrane is essential, it is strong and durable enough to prevent screed leaking out and lifting insulation off of the floor.

Q: Will screeded rooms need to be ventilated whilst drying?

A: Yes, very slight ventilation is good, wide open windows, doors and down droughts, however, will cause floors to crack.

Q: How long after pouring will I be able to walk on the floors?

A: This depends on which product you have installed, drying times are between 24 – 72 hours after installation

Q: Can I force dry my floors with underfloor heating?

A: Absolutely NOT! This will cause screed to crack resulting in catastrophic floor failure. You can however after 7 days with most screeds, leave the underfloor heating on its lowest setting.
