Ceresit CT34 is a Smooth White color Mineral Plaster made by 'German experts' used to make smooth surfaces on reinforced layers in complex thermal insulation systems.

Smooth Render can be used to repairing traditional and cement-lime plasters inside and outside the buildings. 

CT34 is mainly used for smooth mineral substrates on reinforced EWI (External Wall Insulation) systems.

It may be applied both to fill deep losses (e.g. chases after installation work) and to smooth the plaster surface as well.

The properties of CT34 make it possible to apply thin layers on the walls and ceilings, to cover rough and uneven cement and cement-lime plaster surfaces.

The plaster can be painted after 24 hours - when the layer will be dry, using acrylic paint CT42 or silicone paint CT48 and CT49.

Assumed consumption of CT34 Render - approximately 1.0 kg/m2 per each mm of thickness (approx. coverage 8m2 per bag)

Thickness of complete plaster layer must be up to 5mm!


Key Points:

 · Flexible

 · Hydrophobic

 · Easy to apply

 · Good adhesion

 · Vapour permeable (breathable)

 · Resistant to weather conditions

 · Reinforced with micro-fibres



The whole content of the packaging should be poured to the previously measured amount of clean, cold water and mixed by means of the drill with the mixer until the homogenous mass without lumps is obtained. 

Wait for 5 min. and mix one more time - add a small amount of water if it is needed.

The plaster should be applied and smoothed with the metal long float.

When the material becomes thicker (after 90 min.) it may be structured with the Styrofoam long float.

The time can be shorter or longer it depends on thickness of layer or weather conditions. 



Application should be performed in dry conditions with the substrate and ambient temperature from +5°C to +25°C. 

All the data refer to the temperature of +20°C and relative air humidity of 65%. 

Faster or slower material hardening can occur in different conditions.

CT34 contains cement and while mixed with water it shows alkaline reaction. 

Therefore skin and eyes should be protected. 

In case of contact with eyes they should be rinsed with water and the medical practitioner should be consulted.

No matter whether you choose a local installer or a national company, there’s a few tips to help you find the right installer for your home insulation improvements, such as asking for recommendations and making sure that they’re part of a certification scheme. This makes sure that they have the right skills and standards of workmanship to carry out the installation, and you can be sure that they know exactly what they are doing.


1. Thermal inspection picture in portfolio

It’s worth seeing a installer’s previous work. There’s no harm asking if you can see any properties nearby that they’ve installed insulation in. Best way would be to see Infrared Thermal Imaging Inspections. Thermal cameras spot small, but key changes in temperature in different areas of a house, identifying problematic areas that the human eye never could and some that a visual inspection could only hypothesize.

2. Reviews

Along with checking recommendations and previous work, finding reviews online can often be a great way to find out if they provide a good service or not. However, it’s best not to solely rely on reviews you may find or review websites, as there’s no controlling who writes them.

3. Compare prices

Comparing prices will also ensure companies can’t take advantage of you and give you a fair price. 

4. Word of Mouth

The best way to find a great insulation installer is through recommendations. Make sure you ask friends and family. They will most likely give you their honest opinion and can tell you from first hand experience.


Whether you require a wall, cladding, external wall, loft or floor insulation fitted, you can find and hire your local insulation installers from popular UK web pages. A simple internet search will return thousands of potential installers near your area.
