BioCement GM 1.5 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. BioCement GM 1.5 can be applied to all types of portland cement surfaces, cementitious boards, MGO mineral boards, and almost any type of masonry surface prepared correctly.

BioCement GM 1.5 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.


BioCement GM 1.5 is a historical slaked lime plaster, ideal for interior and exterior surfaces, applied on masonry or sheetrock surfaces to provide a classical stucco finish with chromatic color variability. BioCement GM 1.5 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. BioCement GM 1.5 has been formulated to form to a slow set to permit application on large surfaces without “freezing” or setting prematurely. BioCement GM 1.5 can be applied for exterior finishes without the risk of damage from freeze/thaw, water, or damage from UV. BioCement GM 1.5 finish provides a flat, opaque finish with sublime shades of color, or with a rough finish using a sponge trowel. 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.

BioCement GM 1.5 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. BioCement GM 1.5 is an organic paint material as described in the Bio Category description.


Slaked lime coating according to UNI 8681 with no organic stabilizers.




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



1ST COAT     Prepare surfaces for non-mineral bases or portland cement bases by applying a mineral primer with BioGrip Primer Medium (see instructions). Apply one (1) coat of BioCement GF 1.0 on primed base, applying in an even finish. Allow to dry for 8 – 12 hours. Apply one (1)-coat of BioCement GM 1.5, applying an even finish. Allow product to set and finish with a sponge trowel. For a travertine finish, provide same finish as with a sponge trowel then pass over with a metal trowel and flatten surface at 0° – 5° angle. Burnish surface to desired finish.

2ND COAT     In most cases a 2nd coat is not required.

SKIPPED TROWEL     For a skipped trowel effect, apply one (1)-coat of BioCement GM 1.5 as indicated for a 1st coat, then re-apply additional material using a steel trowel and apply irregular amounts of product, in a sporadic fashion, onto 1st coat base. Application should be made in a 360° pattern, always random, observing periodically from a slight distance to adjust hand movement so that irregular surface finish has a harmonious finish. Allow product to completely dry.

BRUSH APPLICATIONS     In some instances for very specific applications techniques, using a base of BioCement GM 1.5 with either a skipped trowel or sponge finish, visibly dry, use a wet brush to smooth down the rough surface. Allow product to completely dry.

Roller Applications

This product is not recommended for roller applications.

GRAIN SIZE     1.5 mm


Apply with a stainless steel trowel designed specifically for stucco plaster finishes.


Prior to utilizing ready-to-use masonry products from new buckets, it is highly recommended to mix product with a drill and masonry paddle to prep material for easier removal and application. Mixing masonry products with a drill properly mixes water content and heats up the material so it renders it more pliable.


Allow a drying time for the 1st coat of BioCement GM 1.5 of 8 – 12 hours for any decorative finishes using potassium silicate or lime paints. Typical application is one (1)-coat.

Do not apply BioCement GM 1.5 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 BioCement GF during the initial carbonization period in the case of rain and subsequent rapid cooling on semi-dried Marmorino.

It is advised not to apply mineral paints or plasters in direct sun with temperatures over 75°F – 80°F / 20°C – 24°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 1st coat of plaster, or if significant time has passed between 1st coat of base application and the initiating of the 2nd coat. 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.


Approximately 75 ft2 / 7 mt2 – 150 ft2 / 14mt2 depending on absorption and type of base. Determine exact consumption by performing a test on the surface to be treated.


Plastic buckets of 1, 5 and 15 liters.


Make sure base is solid, dry and well cleaned, prepared with skill. It is recommended to observe the rule VOB DIN 18 363, Part C, paragraph 3.

New Sheetrock

Virgin sheetrock surfaces must be primed or consolidated prior to application of plaster anchor coat and lime plasters. Sheetrock types are varied and types can affect final results depending on type of sheetrock.

Standard Gray sheetrock ½”- ¾”fire rated and non fire rated

Sheetrock finish should be completed to a Level 3 – 4.

Apply one (1)-coat of EcoForte Consolidator diluted with water 200% and apply to all surfaces with a brush, roller or sprayer. Apply a 2nd coat of EcoForte Consolidator diluted with water 50% and re-apply only on sheetrock compound plaster wherever visible. Allow to dry for 8 – 12 hours.

Other recommendations


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 parallel line, and use wedges or shims to correct discrepancies on the finished stud wall, so that during the application of BioCement GM 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 GM 1.0 (typically 1/16″ thick millage) can be used to fine tune discrepancy’s, 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. Apply BioCement GM 1.5 for desired finish as indicated in instructions above, eliminating a 2nd coat of GF 1.0.


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. Allow product 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 2nd coat of BioCement GM 1.5 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 must be primed with an anchor coat of BioGrip Primer 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 Primer Medium diluted with water 40% and apply to all surfaces with a brush, roller or sprayer. Allow to dry for 8 – 12 hours.

Apply BioCement GF and GM as indicated in instructions above.


Prepare butt joints with manufacturer’s recommendations for tile backer boards as may apply using mesh tape and modified acrylic mortar or thin-set as directed.

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

Apply BioCement GF and GM as indicated in instructions above.


BioCement GM 1.5 cannot be used on Portland Cement based floors, sidewalk or driveways.

New Cement Stuccos


New portland cement should not be painted for about 21 – 28 days to ensure proper anchoring and drying. Apply 1 coat of BioGrip Micro or Medium diluted 30% with water, 4.5 liters water to one (1)-bucket 15-liters of product; allow to dry for at least 12 hours. Apply BioCement GF and GM as indicated in instructions above.

NHL 3.5 & 5.0 CEMENT

NHL 3.5 and NHL 5.0 natural cements do not require the use of a primer when applying BioCement GF 1.0 and GM 1.5. Apply BioCement GF and GM as indicated in instructions above.


Chalking surfaces, which could prevent the proper anchoring of the cement coating must be removed and pressure washed. Apply Potassium Silicate Concentrate, diluted 100% with water (1:1) on all damaged surfaces, applying 2 – 3 coats in rapid succession and allow to dry for at least 12 hours. Allow to dry for at least 12 hours. Apply 1 coat of BioGrip Micro or Medium diluted 30% with water, 4.5 liters water to one (1)-bucket 15 liters of product; allow to dry for at least 12 hours. Apply BioCement GF and GM as indicated in instructions above.


Cement surfaces showing efflorescence should be removed with acid and thoroughly rinsed with water. Apply Potassium Silicate Concentrate, diluted 100% with water (1:1) on all damaged surfaces, applying 2 – 3 coats in rapid succession and allow to dry for at least 12 hours. Apply 1 coat of BioGrip Micro or Medium diluted 30% with water, 4.5 liters water to one (1)-bucket 15 liters of product; allow to dry for at least 12 hours. Apply BioCement GF and GM as indicated in instructions above.

For coatings on surfaces damaged by the saltpeter or efflorescence no guarantees can be provided.


When new stucco repairs are performed on older cement stuccos, apply EcoForte Consolidator diluted 50% with water (2:1), to older surfaces prior to applying new cement stucco. Dirty and/or contaminated surfaces should be cleaned and any attached algae removed manually or by mechanical means, i.e., with a high-pressure washer. Stucco damaged by algae or mold should be treated with EcoDis. Apply EcoForte Consolidator to any new stucco repairs with the same dilution. Apply 1 coat of BioGrip Micro or Medium diluted 30% with water, 4.5 liters water to one (1)-bucket 15 liters of product; allow to dry for at least 12 hours.
