Application Guide: Conforming to 3.5 A. Application Guide. 2. Plan the work properly. a. Ensure entire surfaces are free of dust and debris before application. b. Apply to shaded surfaces in a timely manner working ahead and away from direct-facing sun during application. c. Avoid direct sun exposure onto wet plaster. d. Do not apply slurry onto surfaces above 90 degreesF, direct wind above 10 mph, or when temperature fluctuations exceed 50 degreesF differentials from day to night. e. Protect slurry surfaces from rain during application. f. In indoor/interior or enclosed areas, provide indirect well-distributed air circulation and ventilation with protective screens to deflect concentrated or forced air onto freshly applied slurry. g. Moist-cure completely dried plaster by flooding entire surfaces with clean water at 0 PSI (no pressure). 1) Begin curing procedure using "appearance-based determination" for each slurry layer. 2) As applied slurry dries, the appearance of the slurry changes from dark to light. When dark, it is visibly damp. As water evaporates from the layer, it becomes lighter in contrast to the damp areas. In mid-transition between damp and dry, the surface appears mottled. Once mottling disappears, additional moisture-curing cycles can begin. 3) Weather conditions and plaster layer thickness affect how quickly the slurry transitions from damp to dry. In dry weather, moisture-curing cycles might begin the day of application, while in humid weather the cycles might begin the following day. Appearance- based determination ensures proper sequencing of the moisture-curing coats for each applied layer of slurry. 4) Ensure complete coverage of all surfaces including terminations at soffits, inside and outside corners, and window/door returns. This constitutes the first (1st) moisture-curing cycle. Additional moisture-curing cycles continue for the stated number of days for each installed layer of slurry - 3 times over a 3 day period. 3. Application: a. Mixing Methods 1) Bucket Mixing Method: Mix slurry with clean water using helical mixing paddle on a heavy-duty mortar mixing drill motor (see Technical Data Sheet). a) Fill the slurry manufacturer's measuring bucket with clean water to the referenced product margin line. b) In a clean 6-gallon (23 L) plastic bucket, pour half of the measured water. c) While stirring the water at low RPM, add mortar from the bag at a rate to prevent clumping of the material. Continue adding water from the measuring bucket and dry mortar until bag is empty. d) Once the dry powder is wetted, mix for additional 3 minutes maximum. Allow 5 minutes rest to fully hydrate and then stir to relax the batch. Over-mixing mortar will cause loss of strength. Keep bucket covered to extend working time to about 1 hour. 2) Onsite Slurry Mixing Station Method: Follow equipment manufacturer's recommendations. Do not mix more water than recommended by the slurry product technical data sheet. 3) Auto-mixing and Spray Application Equipment: Follow equipment manufacturer's recommendations. Do not mix more water than recommended by the plaster product technical data sheet. b. Base Coat Slurry: 1) Review the BioLime Application Guide: https://biolime.com/pro/application-guide.com/ 2) Ensure surface is free of any dust and debris. 3) Surface Hydration: Dampen mineral-based surfaces relative to their absorbencyhighly absorbent surfaces require more hydration. Once water is absorbed from the surface, application may begin. 4) Apply slurry in one lift with even distribution to a minimum 1/8 inch (3 mm) layer thickness. 5) Brush surface smooth and level to the surface plane. Provide finish as directed by the Architect. 6) Moist cure for at least 3 days to ensure bond and proper mineral curing before applying Finish Coat. a) As slurry dries out, its surface develops a mottled appearance. b) Before the slurry dries completely out, mist with clean water to re-saturate the surface. c) Repeat as instructed in Application Guide. c. Finish Coat Slurry: 1) Review the BioLime Application Guide: https://biolime.com/pro/application-guide.com/ 2) Ensure surface is free of any dust and debris. 3) Surface Hydration: Do not saturate surface. Dampen the Base coat relative to its absorbency. Once water is absorbed from the surface, application may begin. 4) Apply slurry to 1/8 inch (3 mm) layer thickness. 5) Provide finish as directed by the Architect. 6) Moist cure for at least 3 days. (Review Curing Section in Application Guide). a) As slurry dries out, its surface develops a mottled appearance. b) Before the slurry dries completely out, mist with clean water to re-saturate the surface. c) Repeat as instructed in Application Guide. 4.

Download and attach the BioLime Application Guide for complete application procedures: 3.7 https://biolime.com/pro/appication-guide.com/. 3.8 The plaster applicator's acknowledgement of receipt is essential. A. Application Guide: Conform to all procedures listed in the BioLime Application Guide. Review product data sheets, manufacturer's written instructions, and provisions of the Contract Documents. B. Planning: 1. Plan the work properly. 2. Ensure entire surfaces are free of dust and debris before application. 3. Apply to shaded surfaces in a timely manner working ahead and away from direct-facing sun during application. 4. Avoid direct sun exposure onto wet plaster. 5. Do not apply plaster onto surfaces above 90 degrees F (32 degrees C), direct wind above 10 mph (16 km/h), or when temperature fluctuations exceed 50 degrees F (10 degrees C) differentials from day to night. 6. Protect plaster surfaces from rain during application. 7. In indoor/interior or enclosed areas, provide indirect well-distributed air circulation and ventilation with protective screens to deflect concentrated or forced air onto freshly applied plaster. 8. Moist-cure completely dried plaster by flooding entire surfaces with clean water at 0 PSI (0 Pa) (no pressure). a. Begin curing procedure using "appearance-based determination" for each plaster layer. b. As applied plaster dries, the appearance of the plaster changes from dark to light. When dark, it is visibly damp. As water evaporates from the layer, it becomes lighter in contrast to the damp areas. In mid-transition between damp and dry, the surface appears mottled. Once mottling disappears, additional moisture-curing cycles can begin. c. Weather conditions and plaster layer thickness affect how quickly the plaster transitions from damp to dry. In dry weather, moisture-curing cycles might begin the day of application, while in humid weather the cycles might begin the following day. Appearance- based determination ensures proper sequencing of the moisture-curing coats for each applied layer of plaster. d. Ensure complete coverage of all surfaces including terminations at soffits, inside and outside corners, and window/door returns. This constitutes the first moisture-curing cycle. Additional moisture-curing cycles continue for the stated number of days for each installed layer of plaster - 3 times over a 3 day period. C. Mixing Methods: 1. Bucket Mixing Method: Mix plaster with clean water using helical mixing paddle on a heavy-duty mortar mixing drill motor (see Technical Data Sheet). a. Fill the plaster manufacturer's measuring bucket with clean water to the referenced product margin line. b. In a clean 6-gallon (23 L) plastic bucket, pour half of the measured water. c. While stirring the water at low RPM, add plaster from the bag at a rate to prevent clumping of the material. Continue adding water from the measuring bucket and dry plaster until bag is empty. d. Once the dry powder is wetted, mix for additional 3 minutes maximum. Allow 5 minutes rest to fully hydrate and then stir to relax the batch. Over-mixing plaster will cause loss of strength. Keep bucket covered to extend working time to about 1 hour. 2. Onsite Plaster Mixing Station Method: Follow equipment manufacturer's recommendations. Do not mix more water than recommended by the plaster product technical data sheet. 3. Auto-mixing and Spray Application Equipment: Follow equipment manufacturer's recommendations. Do not mix more water than recommended by the plaster product technical data sheet. D. Base Coat Plaster: 1. Review the BioLime Application Guide: https://biolime.com/pro/application-guide.com/ 2.
