General Guidelines for the Application of SURTREAT System
SURTREAT materials are applied to clean substrate surfaces (stone, composite, brick, block ,or concrete).
Surface preparation - Cleaning
Surface preparation can be accomplished in a variety of ways depending on substrate composition, condition, presence of windows, stairwells, other openings, building surroundings such as plant life, walking areas, etc.
Acceptable methods include water cleaning with varying pressure/no pressure, abrasive cleaning, or chemical cleaning depending on the type of substrate and condition. A variety of appropriate cleaning solutions from very mild to rigorous are available from SURTREAT Holding.

SURTREAT Application
SURTREAT application is usually achieved by spraying with low pressure equipment. Less vigorous application methods such as rolling or brushing of the liquid onto the surface can be used.
SURTREAT corrosion inhibitors are applied first in cases where corrosion of metal components is suspected.
SURTREAT reactive penetrants are used to combine with available reactive sites inside stone or composite materials. Please consult your local distributor or Surtreat Holding, LLC for additional instructions and coverage rates.
Additionally transparent penetrating UV resistant sealer can be used for further extend weather barrier where appropriate.
SURTREAT materials are easy to apply, non-toxic, environmentally safe.

Restoration of a Statuary Complex and Church in Duquesne, PA, USA
From 1996 Surtreat Holding, LLC completed a number of preservation projects including Statuary Complex restoration at St. Hedwig Cemetery in Duquesne PA.
The project included application of proprietary SURTREAT chemical materials to monuments and statues and stone components of the nearby St Joseph's Church.
Brief Description of the Problem
The church fascia was composed of locally available sandstone;. cemetery monuments statue foundations were Indiana limestone; statues were composite wire reinforced cement based material. All showed signs of deterioration due to impact of the environment.
Outward visible signs of deterioration were erosion of the substrate surface, cracking, and signs of corrosion of the reinforcing wire and other metal components of the statues.
Objectives
To protect against further deterioration it was necessary to inhibit water penetration and restrict access of airborne pollutants to the reactive sites inside the substrates, to strengthen the substrates' surface so to prevent further erosion, and inhibit corrosion of steel reinforcement inside the composite statues.
Work Performed
All surfaces were cleaned using slightly pressurized water spray or mild non-ionic detergent where appropriate. Cleaning is important as it removes contamination from the surfaces to allow for subsequent application of SURTREAT materials to penetrate more easily.
Application of SURTREAT corrosion inhibitor was performed on the sections of the statues where corrosion of the imbedded reinforcement was visible or suspected. SURTREAT TPS XII penetrates porous reinforced substrates easily as gas and deposit on steel components. By application of TPS XII corrosion of steel inside the reinforced structure is inhibited.
SURTREAT TPS II was then applied to all stone and composite surfaces. SURTREAT TPS II penetrates as liquid and combines with the reactive sites of substrates to strengthen the surface, prevent further deterioration and erosion as well as inhibit moisture and contaminants penetration. SURTREAT TPS II is also known to reduce the penetration of gaseous substances by reducing substrate porosity. Treated surface becomes resistant to attack and penetration by various environmental pollutants in effect becoming more chemically inert. SURTREAT TPS II does not exist on the surface of the substrate following the application. All chemical and physical improvements in substrates properties are internal to the structure.
An appropriate version of SURTREAT REPEL water barrier was applied as final treatment to further protect substrates against coming in contact with atmospheric contaminants in liquid form. Although SURTREAT REPEL exists close to or on the surface of the substrate.it's advanced chemistry produces completely invisible layer of protection which does not change color or degrade in the environment or when exposed to UV rays.
Project Results
The total effect of the combined application of SURTREAT materials to the substrates is described as providing for more chemically inert, more durable (harder) substrate surfaces resistant to water and airborne pollutants penetration. The protection becomes a completely transparent, invisible, and internal part of the structures.
The quantifiable part of the SURTREAT effect is also described in the study performed by Raba Kistner laboratories during preservation projects on buildings composed of Texas limestone.
