Stucco Seta

A pearlescent finish reminescent of precious silk

It is slightly rough and matte, but with a soft iridescent pearl effect, visible when rays of light hit the wall. It has the chiaroscuro effect and the smooth touch typical of silk.

Seta in Italian means silk. Its look is due to the high quantity of metallic pearl particles it contains.

Description

This is one of the most elegant lime-based wall finishes. It’s slightly rough and matte, but with a soft iridescent pearl effect visible when rays of light hit the wall. It has the typical chiaroscuro effect of the silk. Seta in Italian means silk. Its look is obtained by adding a high quantity of metallic pearl particles in the material.

Seta mimics this soft, natural fabric’s ability to reflect “shades of luminosity”. The feel of silk is also enhanced by its soft and cool, slicky touch.

Color

The product is white and can be tinted in any color without Color System.


Application

The application is very similar to that of Marmorino Velvet.

Tools necessary for application: a normal big trowel, a good big trowel, a plastic trowel, a sponge float.

Before the application

Don’t apply in temperatures below 6°C / 43°F.

Protecting the work area: Apply masking tape and protective material over the baseboards and around windows and doors.

Primer application: One coat of Primer Quartz is applied with roller or brush to a uniformly smooth, clean surface and allowed to dry completely (3-5 hours). It is necessary to apply the primer on all surfaces with the exception of plasters made of lime and sand. These have a similar composition to marmorino.

Preparation of the Seta material: After opening the container of Seta, remove any water on the surface, and mix for about 30 seconds using an electric mixer until homogenized. Add the coloring pigment and mix until the color is completely uniform. To correctly choose and mix the color read “General Rules for Correct Color Mixing” described in our Color System. Remember that lime loses its viscosity once shaken. If the material, after mixing, is too loose wait it resting 6 to 8 hours before using.

Application

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 other sources of light come from such as the 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.

During application be sure the work area isn’t too damp or warm to avoid problems with application times.

  1. Apply a thin, even coat of ‘Seta’ over the entire surface with a metal trowel. Avoid making too many ridges and allow it to dry completely (6-8 hours). The first coat can be white even if you plan to have a colored finish. If the final color will be dark, it is best to remove the masking tape from around doors, windows and baseboards and reapply it; otherwise, a strip of white may be visible when the tape is finally removed. Therefore, remove the tape and replace it approximately 1/16” distant from the original position of the tape.
  2. Second coat: if you apply the second coat as evenly as possible with a metal trowel you will get little or no chiaroscuro effect, but if you apply it “badly”, that is, with areas with more material close to areas with less, you will get more chiaroscuro effects, especially with dark colours.
    To do this coat make sure the blade-edge of the trowel is always clean and free of imperfections.
    Usually the second coat is applied over the entire surface before applying the third coat. But on large surfaces in hot, dry conditions it might be necessary to have a second person begin to apply the third coat while the first completes the second coat.
  3. The third coat should be applied before the second coat has dried completely. To recognize when this is, you should observe that the water that was on the surface has been absorbed, but the plaster still appears slightly damp. The second coat should have almost completed the shrinking process that typically occurs with lime-based products. With ideal room temperatures, this occurs after about 15 minutes, the time it usually takes to apply the second coat to a medium-sized wall.
  4. The third coat will be applied over this even surface. No specific care need be taken when applying it since this final layer will be smoothed out almost immediately with a dry sponge float. It is difficult to say how much time you need to wait before using the sponge float because it depends on how absorbent the wall is and what the temperature is. You’ll know if is too soon because you will see small ridges forming as you use the sponge float. Generally the plaster should be damp enough to be able to smooth the surface moving the sponge float in opposite sweeping directions several times. This will fill in pits and flatten ridges without leaving marks on the wall.
  5. The sponge float will need to be cleaned from time to time of excess material which has accumulated on its surface. To do this, gently scrape the surface of the sponge float on the edge of a metal trowel, and then scrape the excess marmorino into a container to be reused later.
  6. Before it dries completely, go over the wall with a plastic trowel which has smooth, rounded edges. As when using the sponge float, you will know when to perform this phase of the smoothing process by observation. It is too early to use the plastic trowel when you leave small ridges in the plaster and too late when you are unable to smooth out the roughness left from using the sponge float.
  7. The plastic trowel should be pressed almost flat on the wall (with a 25-30° angle) moving it in opposite sweeping directions to avoid making ridges. It is advisable to use a strong light source parallel to the walls when smoothing out the surface to detect imperfections you may create while moving the trowel over the surface. The wall will be finished when it appears almost shiny when viewed against the light. You will observe – especially with darker colors – that the smoothest parts appear the darkest.
  8. Remove all tape and protective material before the plaster is completely dried to avoid chipping and cracking along the taped edge. In fact, the tape can be removed right before the last phase where you use the plastic trowel.

Application variations

This versatile material can achieve a number of special effects:

Note that with our wax and colorants, you can always change the color even with the passing of time. To make the wax lighter, all you have to do is add our “White Dye”; to make it darker, tint it with the color of your choice. It is always advisable to try out the color on a sample board or on part of the wall which is not so visible.

Our metallic glitter or pearlescent waxes can also be used to get veiled effects.

Damasque effect

A Damasque effect can be obtained by applying a very thick second coat of Seta material and passing over it immediately with a completely flat, metal trowel always moving in the same direction (horizontally or vertically). Ridges will be formed in this way which should then be pressed down lightly with a plastic or metal trowel before drying.

Other effects

You can use a metal trowel instead of a plastic one in the final phase of the smoothing process to leave dark marks on the finished surface. These are transferred from the metal trowel to the smoothest areas. This effect is used mostly on dark finishes.


Protection and maintenance

Apply our acrylic wax for EpoFloor which guarantees waterproofing and protection against all types of dirt. There are three kinds available: Flat, Semi-gloss and Glossy, but we suggest you use the Flat (Matte) one, since the shinier wax reduces the contrast between the brightness of the metallic pearl powder and the rest of material that is naturally matte. Apply it, diluted up to 100%, preferably with a spray bottle or with a brush.

To clean natural finishes with no protection: The most practical way to clean this type of finish is with a white rubber eraser or sand paper (P 220-320). It’s very easy to clean most dirty areas by simply using sand paper and dusting off the powder residue.

The soft reflection of the light moves from one side to the other depending on your point of view and on the source of the light.
