8.2 Exposure Controls

As the use of adequate technical equipment must always take priority over personal protection equipment, make sure that the workplace is well aired through effective local aspiration or bad air vent. If such operations do not make it possible to keep the concentration of the product below the permitted workplace exposure thresholds a suitable respiratory tract protection must be used. See product label for hazard details during use. Ask your chemical substance suppliers for advice when choosing personal protection equipment. Personal protection equipment must comply with the rules in force indicated below.

HANDLING PROTECTION
Protect hands with category III (ref. Directive 89/686/EEC and standard EN 374) work gloves, such as those in PVA, butyl, fluoroelastomer or equivalent. The following should be considered when choosing work glove material: degradation, breakage times and permeation. Work glove resistance to preparations should be checked before use, as it can be unpredictable. Gloves` limit depends on the duration of exposure.

EYE PROTECTION
Wear hood visor or protective visor together with airtight goggles (ref. Standard EN 166).

SKIN PROTECTION
Wear category III professional long-sleeved overalls and safety footwear (ref. Directive 89/686/CEE and Standard EN 344). Wash body with soap and water after removing overalls.

RESPIRATORY PROTECTION
If the threshold value for one or more of the substances present in the preparation for daily exposure in the workplace or to a fraction established by the company`s prevention and protection service is exceeded, wear a mask with an A or universal filter, the class (1, 2 or 3) of which must be chosen according to the limit concentration of use (ref. standard EN 141).

The use of breathing protection equipment, such as masks with organic vapour and dust/mist cartridges, is necessary in the absence of technical measures limiting worker exposure. The protection provided by masks is in any case limited.

If the substance in question is odourless or its olfactory threshold is higher than the relative exposure limit and in the event of an emergency, or when exposure levels are unknown or the concentration of oxygen in the workplace is less than 17% volume, wear self-contained, open-circuit compressed air breathing apparatus (ref. Standard EN 137) or fresh air hose breathing apparatus for use with full face mask, half mask or mouthpiece (ref. Standard EN 138).

FIELDS OF APPLICATION

Grassello Bio Traditional (Venetian Plaster) is a high quality slaked lime plaster ideal for stucco finishes when applied to NHL cements and slaked lime stuccos, permitting endurance cycles that can last intact for centuries. BioGrassello Traditional can be applied to all types of portland cement surfaces, cementitious boards, MGO mineral boards, and almost any type of masonry surface prepared correctly.

Grassello Bio Traditional can be applied to directly to all interior walls surfaces composed of sheetrock, painted or non-painted, using an appropriate primer.

This plaster product is not oil proof, and can be damaged by foods, greases, body oils, color crayons or washable colored markers. Cleaning may damage or change the sheen of the paint.

PRODUCT FEATURES

Grassello Bio Traditional, a true Venetian Plaster, is a historical slaked lime plaster, ideal for interior and exterior surfaces, applied on masonry or sheetrock surfaces to provide a classical plaster finish with chromatic color variability. Grassello Bio Traditional is made in the ancient tradition, with the capabilities to carbonize to masonry surfaces providing decades of durability, withstanding most climatic conditions and not capitulate to environmental stress. Grassello Bio Traditional has been formulated with a high content of “lime putty”, which by its own nature is quick to set. The formula has been adjusted to form to a slow set, as is possible, to ease application. This formula has been created as a “filling” base and finish, with sufficient millage thickness to create a smooth 1st and 2nd coat on semi-smooth and smooth finishes. This is a professional product and requires a trained applicator to apply correctly. Grassello Bio Traditional can be applied for exterior finishes without the risk of damage from freeze/thaw, water, or damage from UV. Grassello Bio Traditional finish provides a gloss finish with slight translucent depth and sublime shades of color. A non-acrylic product that provides superior adhesion than typical gypsum lime plasters, with custom color matching available for most medium dark to light colors.

A 100% natural mineral product, completely permeable, breathable, absorbs CO2, provides good anchoring power with mineral surfaces by carbonization. Provides protection against the formation of bacteria that forms mold. Product is considered a natural organic product, ideal for use in homes, schools, and hospitals and work sensitive areas.

Grassello Bio Traditional is specifically designed to be tinted with natural oxide earth tints and 0% VOC colorants to increase esthetic color values with minimal impact to the environment and to provide toxic free air quality for indoors. Grassello Bio Traditional is an organic paint material as described in the Bio Category description.

TYPE OF PRODUCT

Slaked lime coating according to UNI 8681 with 3% organic stabilizers. No acrylic binders used.

SHEEN FINISH

Extra High Gloss

COLOR

White Base. Color tint up to 8% max with approved tints. Custom color tint matching is available.

APPLICATION CYCLE INSTRUCTIONS

TROWEL APPLICATIONS

1ST COAT     Prepare surfaces for non-mineral bases or Portland cement bases by applying a mineral primer with BioGrip Medium (see instructions). For best performance, durability, and proper carbonization, apply one (1)-coat of BioCement GF 1.0 on primed base and allow to dry for 8 – 12 hours. Surface should be smooth and even, or for decorative effects, BioCement GF 1.0 can be lightly skip toweled, or sponge finished, to heighten decorative effects with final coats of Grassello Bio Traditional.

2ND COAT     Apply a 2nd coat with BioMarmorino Flat or Satin, on the prepared base of BioCement GF 1.0. Use a round edge trowel specially designed for fine plaster applications. Apply a thin layer of product and cover entire surface and then remove excess by tilting trowel to approximately 30°. Once excess has been removed, smooth surface using a 30° angle, compressing plaster using the same angle, in arched trowel motions, with a forward and backward direction, to create a smooth surface as is possible and allow product to slightly set. Do not overwork surface with a trowel after the initial covering of the surface, but allow the moisture to be absorbed into the base, so as product appears to have slightly set. Then begin to compress setting coat of Marmorino, pushing gently with the weight of the trowel to create a perfectly smooth and flat surface. Allow moisture to reduce again, and continue with arched trowel motions, in a forward and backward direction, to compress surface to achieve a uniform, even, and glass like type surface. Do not continue to overwork surface with trowel motions, permitting sufficient time between compressions with a trowel for the plaster to dry naturally. Maintain a clean trowel at all times during finishes. At the last phase of drying and finishing, using a 5° – 15° angle on the finish trowel, burnish the Marmorino surface to achieve the desired sheen and decorative effect. Typical time lapse for this product to set between initial application and final burnishing is 1 – 2 hours when applied to a BioCement GF 1.0 or natural stucco base.

3rd COAT     Option 1     Apply Grassello Bio Traditional onto prepared base of BioMarmorino Flat or Satin, using the same technique as described above for BioMarmorino. Smooth the finish as much as is possible during the initial application process, as Grassello Bio Traditional will pull quickly. One (1)-coat of Grassello Bio Traditional may be sufficient depending on finish and type of decorative effect desired. Traditionally, and in most cases, it is strongly suggested to not complete the last phase of burnishing with a one (1)-coat application, but to apply a 2nd and 3rd coat. Once the Grassello Bio Traditional has visibly dried, repeat the last step again, applying less material than at the initial onset of applying and covering the surface. Apply only enough material as is necessary to cover a small surface area, pulling tightly and then compress. Continue this operation repeatedly until the entire surface has been covered. Trowel smooth as is possible to permit a continuum between short applications so to create a very smooth and flat surface. Follow burnishing instructions indicated above for 2nd Coat. After product has almost completely dried, burnish again with a polishing trowel, pressing with a firm 0° – 5° angle, and with a back and forth movement, polish Grassello Bio Traditional to the highest sheen possible. Typical time lapse for this product to set between initial application and final burnishing as a 4rd coat is 10 – 20 minutes.

Option 2     Follow instructions as indicated in Option 1 except substitute 2nd and 3rd application of Grassello Bio Traditional with Grassello Bio High Gloss. This product contains less calcium carbonates, thus less filling capacity, slightly semi-transparent, to permit more translucency and a higher shine or polish. Burnish final phase of finish as indicated above.

When situations require, final coat of Grassello Bio can be pre-diluted with a very small amount of water to permit a thinner coat application when applying multiple coat finishes. This technique should be avoided except when being applied by a master finisher.

Brush Applications

This product is not recommended for roller applications.

Roller Applications

In some instances for very specific applications techniques, using a rough base of BioCement GF or GM with either a skipped trowel or sponge finish, Grassello Bio Traditional can be slightly diluted with water and using a paint brush, applying in a crisscross pattern, can create an unusual, non-polished, durable painted masonry surface. For further visual interest, the paintbrush application can be flattened with a trowel and lightly burnished to enhance the over-all effect. This is a special effect and cannot be used for creating traditional smooth and polished surfaces as is typical with Marmorino. This is a master plasters application technique and should only be utilized by a master plasterer.

GRAIN SIZE     0.01 mm / 0 aggregate

TOOLS

Apply with a polishing trowel designed specifically for BioMarmorino or Grassello Bio plaster finishes. Use stainless steel or plastic trowels as may be needed.

DRYING TIME

Allow a drying time for the 1st coat of BioCement GF 1.0 or any of the BioMarmorino’s for at least 8 – 12 hours, and with successive coats time will vary greatly depending on thickness and type of finish desired. With lower temperature and humidity more time may be needed between coats.

Do not apply Grassello Bio Traditional on the exterior if there is a risk of thunderstorms or showers during the 12-hour drying time needed for product to dry and carbonize correctly. If this risk could occur and the surface is essentially visibly dry and hard to the touch, wet surface quickly and evenly with water, starting from the bottom of the wall moving upward, without using force or sharp water directional spraying, and allow to dry. This process will help protect against flashing or water damages to the Grassello Bio during the initial carbonization period in the case of rain and subsequent rapid cooling on semi-dried Grassello Bio.

It is advised not to apply mineral paints or plasters in direct sun with temperatures over 75°F – 80°F / 24 – 20°C, using shaded sides of walls for applications. Extremely hot and dry climates may require the masonry base coat to be thoroughly dampened prior to application of 2nd coat of BioMarmorino or Grassello Bio Traditional on BioCement GF 1.0, or if significant time has passed between 1st coat of base application of BioCement GF 1.0 and the initiating of the 2nd coat applications. It is advised to not apply any mineral paints or plasters in temperatures over 88°F / 31°C. Never allow mineral paints or plasters to be stored or placed, with or without lids, directly in the path of the sun. Always keep lids on as is possible during work cycles to prevent the absorption of air, as most mineral products will carbonize in the presence of CO2.

CONSUMPTION/COVERAGE

Approximately 500 ft2 / 46 mt2 – 800 ft2 / 74 mt2 depending on absorption and type of base. Determine exact consumption by performing a test on the surface to be treated.

Other recommendations

SCREED BOARD USE

For crown or baseboard installations which require true straight wall finishes where caulk or paint is not an option for finishes, it is recommended to install a screed board, both for crown and/or base, to extend 1/8″ beyond surface of sheetrock, using a string to create a that during the application of BioCement GF 1.0, the material can be used to correct any uneven surfaces resulting in dips or concave surfaces so as to produce a straight wall. The BioCement GF 1.0 (typically 1/16″ thick millage) can be used to fine tune discrepancies, not applying more than 3/16″ material at a single time, otherwise cracks may form during drying period. Several coats may be required to correct overly deep wall distortions.

TRIM & FLOOR SCHEDULES

It is suggested for all plaster finishes that where possible, window, door, and finish trim, should not be installed until application of 1st coat of BioCement GF 1.0, and 2nd coat of BioMarmorino Flat or Satin. Allow finish to dry for 8 – 12 hours before installing trim.

Prep, prime, paint or varnish trim with all coats with the exception of the last finish coat. Complete application of 1st and 2nd coat of Grassello Bio Traditional and allow to dry for 24 – 48 hours before continuing applying final application of finishes for trim. Finished trim edges adjacent to plaster walls should be taped with an appropriate removable type to reduce damage to a minimum to trim finishes after completion of plaster applications.

Floor finishes should also be completed to the same condition as is typical for trim schedule indicated above. It is recommended that final coat of floor varnish finish be applied after all plaster and paint schedules have been completed. Trim and floor applicators will have to perform due diligence when applying final finishes as all plaster finishes may be damaged if paints or varnishes are applied in error onto finished plaster walls.

PAINTED SHEETROCK

Painted sheetrock must be primed with an anchor coat of BioGrip Medium diluted with water at 40% and allow to dry for 8 – 12 hours. Any repairs or patches made with sheetrock compound or similar material must be consolidated with EcoForte Consolidator or BioDomus SuperFlat both diluted with water 25%, and apply to all surfaces with a brush, roller or sprayer. Allow to dry for 8 – 12 hours. It is advised to tape-off all trim areas before the application of any aggregated paints or plasters.

Apply one (1)-coat of BioGrip Medium diluted with water 40% and apply to all surfaces with a brush, roller or sprayer. Allow to dry for 8 – 12 hours.

Apply one (1)-coat of BioCement GF 1.0 as a base plaster coat, applying with a steel trowel to desired finish as a base. Allow to dry for 8 – 12 hours.
