Description

Ecologic™ LithoStep
For the surface repair of brick & stone treads and high-density brick, stone, and concrete substrates

Description:

Ecologic™ LithoStep is a specially formulated repair mortar for Cast Concrete Repair that is derived from Saint-Astier® Lithomex, a vertical Brick and Stone surface repair material. Ecologic™ LithoStep is a modified version of Lithomex and it is useful for horizontal brick or stone tread repairs. Ecologic™ LithoStep can be used either as the base coat or for multiple lift build-ups in second and subsequent coats.

Heavier applications of Ecologic™ LithoStep are required where there is a need to build up a repair in lifts to take up deep material loss. Ecologic™ LithoStep can be built up in 1” lifts daily, including pointing of Cast Stone joints, or in 2” lift increments daily when a stainless steel armature is first anchored into the substrate to support the Ecologic™ LithoStep lift installation.

It is recommended when recreating the final lift over Ecologic™ LithoStep in applications at either the vertical faces of Cast Stone or where there will be no foot traffic but still have high exposure, such as on top of a Cast Stone coping to use Ecologic™ “LithoCast.” Ecologic™ LithoCast, which is also a modified version of Saint-Astier® Lithomex, is used to fully cast missing brick and stone elements or to better recreate a match to the texture and tooling of surrounding Cast Stone when it is applied in the final ¾” -1” coat over Cast Stone facing. See separate Cut Sheet on Ecologic™ LithoCast for its full range of benefits.

Benefits:

Ecologic™ LithoStep has unique qualities that allow it to be shaped immediately or carved using stone carving tools or sanded with PermaGrit® sanding blocks about a week after the final set, depending upon weather and final curing.

For surface repairs to be successful the materials used for the repair need to have certain characteristics. They should:

  • Have a similar but slightly lesser compression strength and tensile strength to that of the original masonry material being repaired.
  • Have adequate bond strength.
  • Have a good modulus of elasticity.
  • Have good vapor permeability.
  • Remain durable.
  • Be capable of being dressed to a similar profile as the original masonry.
  • Remain workable long enough to allow details to be created before an initial set.
  • Simulate the color of the surrounding masonry.
  • Simulate the texture of the surrounding masonry when properly tooled.
  • Be reversible.

Mixing:

Ecologic™ LithoStep can be mixed manually or be mixed mechanically using a drill and paddle mortar mixer, adding approximately 1.1 gallons of water per 55 lb of Ecologic™ LithoStep. For smaller batches mix approximately 64 Milliliters of water to one dry cup of Ecologic™ LithoStep. Mix well for 3-5 minutes. Adjust final water content carefully to the consistency required.* For small quantities mixed by hand, add just sufficient water to make a semi-dry crumbly consistency, beat vigorously for a few minutes, and carefully add a few drops of water at a time until desired consistency is achieved. (8 oz water to 3lbs Ecologic™ LithoStep)

LithoStep Color

Ecologic™ LithoStep is neutral white in color or can be custom colored.

LithoStep Available Sizes

Ecologic™ LithoStep is supplied in 55 lb (25kg) pails to which only mixing water is added. It is also available in units of 3 lbs or 15 lbs containers.
