5.	No primer required. 2 coat system on bare masonry.
6.	Moisture vapor diffusion provides a breathable finish.

A penetrating, low pigment or translucent finish when diluted with Design Dilution or Design Base. Can be used as an opaque, thin-layer protective coating.

a.	Protects concrete from weather and prevents atmospheric pollutants penetration. Surface textures of the concrete, such as board-formed textures, are fully retained and never "filled-in". The surface is natural mineral matte in appearance. At various dilutions with Dilution (Fixativ) or Base, different low-pigment finishes may be achieved or optical problems, such as stains or color differences can be corrected.

e.	Cracked and Irregular Aged Mineral Surfaces:
1)	Substrates that have been patched or have textural differences or hairline cracks may be pre-treated with Romanit mixed in a ratio of 2:1with KEIM Romanit-Slurry-Additive as the base coat. (2 parts Romanit to 1-part Romanit-Slurry-Additive) This is best applied by brush; worked into surface voids, cracks, and irregularities, and will equalize the variable texture of the surface filling in hairline cracks.
f.	Mixing: Stir Romanit before use with an electric drill and paddle attachment to ensure a homogenous mixture and color. Stirring by hand is not adequate because of the heavy bodied nature of the Romanit. Diluted Romanit must be stirred thoroughly to ensure a uniform color, and during application as pigment may settle during application. We recommend dilution of 1-part Limewash and 1 part water as a starting point, and it can be further diluted to create a "wash" or stain effect.

3.	Product: Soldalit ME Photo Catalytic Sol-Silicate Self Cleaning Finish
a.	Application:
1)	Air and surface temperature: 41 to 86 degrees F with relative humidity below 80 percent. Extremely humid or damp conditions will retard the drying times substantially and can lead to problems with early exposure to rain, dew, or other water sources.
2)	Apply only to dry surfaces and in dry weather where rain is not forecast for 24 hours. 
a)	Do not apply in direct sun or to sun-heated substrates or in strong wind. 
b)	Surfaces must be protected after application from rain, wind, and direct sun until they are completely cured or a minimum of 24 hours.
3)	Apply by brush, roller, or airless spray.
a)	Brush: Use a nylon/polyester brush.
b)	Roller Use a 1/2 to 3/4 inch nap synthetic roller cover.
c)	Airless Spray:
1)	Pressure: 3000 psi, minimum.
2)	Tip: 0.035 inch.
3)	Remove filters from gun and pump, use 30 mesh filter on siphon tube.
d)	Translucent Metallic Applications:
1)	Metallic Mineral Finish may be diluted in any ratio with Design Dilution/Thinner depending on the desired translucency. It is recommended to coat trial areas to determine the desired dilution ratio and opacity. Keep diluted Metallic Mineral Finish well stirred before and during use as metallic pigment will settle quickly. Do not add water. It is important to work swiftly using wet-on-wet application to maintain a wet edge to a corner or architectural feature. Never stop applications in the middle of a wall. Various metallic techniques can be achieved and should be tested before starting.
e)	Opaque Coating:
1)	Two coats of Metallic Mineral Finish can be applied as an opaque metallic finish while retaining the texture of the surface. In this application the first coat should be diluted 10 to 25 percent with Design Dilution and the second coat applied undiluted by brush, roll or spray, keeping a wet edge. It is important to work swiftly wet-on-wet and to maintain a wet edge to a corner or architectural feature. For economy, a first coat of Soldalit All Surface Paint or Innostar Mineral Wall Paint, in a complimentary color, can be used to create a uniform surface for application of the metallic finish.

1.	Application:
a.	Product may be applied by brush, roller, or airless spray.

3)	Airless Spray:
a)	Pressure: 3000 psi, minimum.
b)	Tip: .031 in.
b.	Opaque Finish:
1)	Romanit is typically applied in multiple coats which are needed to develop the unique patina of Romanit. Application techniques will also impact the final appearance of the finish. It is not typically desired to apply Romanit in a smooth and uniform manner, but rather, using random painting technique that results in an imperfect finish. This will add to the "patina" that is often desired from lime finishes.
2)	Application of the first coat by spray, brush or roller can ensure faster and full coverage. Be sure to work the first coat of Romanit into the surface to ensure proper penetration of rough and textured surfaces. For best results out-doors, thin or dilute Romanit with water up to 50 percent. More dilution up to 100 percent of additional coats will add to patina effect.
3)	Subsequent coats can be applied using any application equipment or methods and should be matched to the aesthetic outcome de-sired. Romanit is an "artistic" type of finish with end results dramatically affected by the equipment and methods employed.
4)	For the finish coat it is important to maintain a wet edge by working swiftly across the facade and avoiding lap marks. Do not stop mid-wall and always paint to a natural stopping point at panel edges, corners or other architectural features that break up the facade.
c.	Slurry Application
1)	To apply Romanit as a slurry finish, mix 2 parts Romanit with 1-part Romanit Slurry-Additive to create a heavy slurry mixture. Apply with a wide bristle brush, working the slurry into the surface. Brush marks will remain in the slurry finish, and it will not flow and level to a smooth surface. The slurry finish is used to level out as much, or little of the original surface texture as desired.
d.	Lime Wash Translucent Finish
1)	To achieve a more uniform washed effect, Romanit may be further diluted with water, up to 100% to create a more transparent stain-like finish. Field trials will determine the ultimate dilution ratio, number of layers needed and application equipment and techniques to im-part the desired washed effect. Multiple colors of Romanit may also be blended together, wet-on-wet on the surface in a color-washing technique as desired.
e.	Distressed or Wash Away Finish
1)	Apply a first coat of Romanit as prescribed in the Opaque Finish previously. Once the first coat is dry to touch, or after about 1 hour un-der normal drying conditions, apply a second layer of Romanit. At this point the surface will be completely covered. Allow the second coat to begin drying and immediately distress or wash-away the finish as desired. You may use a garden hose with sprayer nozzle, power washer with low pressure and wide fan nozzle, wet towels, rags, or plastic bristle brush to dis-tress the finish. Remove as much, or as little, of the Romanit as desired. Plan the distressed areas to follow natural water flow on the facade to emulate a natural "aged and weathered" appearance (i.e. distress more around downspouts, corners, at window sills, etc.). If more Romanit is removed than desired, allow surface to dry and reapply Romanit as desired. be applied to emulate the antiqued or dis-tressed lime finishes of old Europe on new or renovation projects, especially on brick and stone masonry.
