Composition
Cream of slaked lime, aged 24 months, sifted through a sieve of 900 micro-stitches per cm/sq. bioPrimer is composed of micro-selected marble dust, natural earth colorants, natural resins, and natural binders.
Characteristics
bioPrimer is a natural mineral product that affords high adhesive capacity. It's highly breathable and acts as a natural biocide that resists bacterium, mildew, and molds.
bioPrimer serves as a base for all materials applied on top of it.
The high adhesive capacity of bioPrimer effectively binds to its permeable foundation, while allowing condensation, moisture, and even driving rain to evaporate from a building fabric. Moisture will never be trapped within a structure. In hot climates, bioPrimer will not trap the sun's heat, crack, fade, or lose its color characteristics.
Among its numerous benefits, bioPrimer is self-healing and features excellent elasticity. Over time, this affords flexibility in settling with the structure it is applied to.
bioPrimer is a solid surfacing product that offers exceptional characteristics for the bio-architecture and GreenBuild sectors, as well as serving as an indispensable product for preservation and restoration projects.
Use
bioPrimer is appropriate for both indoor and outdoor applications, and it's ideal for restoring existing buildings or in new construction to meet GreenBuild objectives.
bioPrimer is primarily used for making walls absorbent and aesthetically uniform before finishing them with bioPittura, bioTinta, or bioMarmo.
bioPrimer has two primary functions:
First, bioPrimer serves as a base-coat/primer prior to being finished with bio-ecological paint or plaster—(bioPittura, bioTinta, or bioMarmo.)
Second, for certain applications, you can directly color bioPrimer with the natural earth pigments of bioLime and achieve a single finishing solution.
Surface
It's important to apply bioPrimer on a porous foundation, so it has an adhesive base and also allows breathability through the wall system.
As for stone and rock surfaces, bioPrimer can be applied on drywall (gypsum board), rock board, wood, cork, straw, cob, or other natural support systems used in true GreenBuild applications.
Note:
If you're applying bioPrimer on existing surfaces previously finished with synthetic products, prepare the surface and remove the entire existing finish by sanding or grinding.
Glass and other non-porous surfaces provide no permeability of the wall system and no adhesive bonding characteristics; therefore, avoid applying bioPrimer to these surfaces.
Application
bioPrimer is appropriate for both indoor and outdoor use.
Note:
When applying bioPrimer, always use application tools that are high-quality stainless-steel. If non-stainless-steel or other iron tools are used, they may cause a potential chemical reaction with the natural lime by shedding particulates. This can potentially cause discoloration of the plaster after long periods of carbonation (drying.)
Using clean water, mist the surface. When sufficiently damp, uniformly apply bioPrimer with a stainless-steel trowel (or other stainless-steel tools, depending upon your desired finish). Always apply bioPrimer to a maximum thickness of 1/16 inch per coat. This allows maximum effectiveness during application, while working to achieve its ultimate intended purposes.
If desired, you can slightly sand the surface with fine sandpaper between each coat. Afterward, wipe the wall with a damp cloth or towel before applying additional coats.
Add as many additional coats as desired in order to achieve the desired uniform finish, always waiting until each layer is dry to the hand before applying another coat.
Warnings
Do not add cement to bioPrimer.
Do not apply bioPrimer on hot walls, under continuous direct sunlight or on a windy day.
This product (like all bioLime products) has an extensive shelf life—10 years—if stored correctly.
In order to store bioPrimer for long periods of time, add a layer of water that thinly coats the remaining bioPrimer in the bucket. Make sure to close the bucket tightly and keep in a cool, dry place.
