ERA STONE plaster is a textured finish with a rich history, tracing back to the Renaissance era when it was first utilised to recreate the appearance of marble. Nowadays, this versatile plaster is used to mimic various rough-hewn stones and produce an array of eye-catching decorative effects.
The final finish is often topped with decorative patinas such as our Velatura to enhance the natural variations in colour intensity typical of any lime plaster.

Application Instructions:
WARNINGS:Water on the surface of the material in the bucket is normal and should be removed before use or addition of colourants. All lime-based products lose their viscosity when mixed and need a period of 6/12 hours after mixing to regain their density. This product is dense, and ready for use; thus it may be necessary to use an appropriate drill attachment to stir for a few minutes to reduce viscosity. Choose the colour and add the toner additive to the container and continue mixing until a homogeneous shade is obtained. Let the product rest for about 5 hours before you begin to use it. We recommend using materials from the same production batch for the same project. If you must use different batches, we suggest mixing their material together to avoid any slight variations in shading. To ensure proper usage, dilution, and application of the products mentioned in these pages, please consult the corresponding technical data sheets. When preparing the surface and applying the materials, we advise using appropriate tools and personal protective equipment (PPE). During application and for the following 72 hours, protect the surfaces from sudden temperature change, direct sunlight, and water. Don’t apply in temperatures below 8°C or above 35°C. During application make sure that the work area isn’t too damp or warm to avoid problems with application times. Remember to have a strong light parallel to the wall and situated on only one of the two sides of the wall you are working on (usually on the same side as other sources of light such as windows). In this way the shadow of the trowel allows you to see the actual state of the finish. Every so often, during the second and third coat, the light should be moved so that the wall doesn’t dry out too much in one spot from the heat of the lamp.
APPLICATION:
Suitable Surfaces for ERA STONE:It can be applied on any surface including drywall or wood panelling as long as a primer is applied first. Suitable for interior and exterior surfaces.
Preparation of the Work Environment:Protect the floor, baseboards, and windows. Remember that alkaline products can leave marks on aluminium and some kinds of wood.
Applying the Primer:Apply the primer with a roller or brush. A primer containing quartz sand is recommended. Lime-based and sand plasters which are clean don’t need to be primed.
Colouring ERA STONE:After opening the container, pour out all the water on the surface, and mix well with an electric mixer for 30 seconds and then pour in all the necessary colorant. Mix well until the colour is homogeneous. During application, remember to always have strong illumination angled at the surface of the wall you are working on. If there is a window, put the light source on the same side as the window to have all the light coming from one side. If the lamp produces a lot of heat, it is best to move the lamp occasionally so that during the second and third coats, one part does not dry too quickly. It is best not to apply in temperatures below 5°C or with elevated humidity.
ERA STONE Romano – an Alternative Application:A more popular application is done using the “plastic grass brush” to draw the ERA STONE effect. Apply and smooth the second coat and create a pitted drawing pressing the surface. Smooth the surface again and if necessary, draw the effect once again with a plastic brush.
