Epoxy Filler Compound
Application Instructions • Excellent surfacer for concrete and steel surfaces • Fills and seals most voids and air pockets in single application • Easily mixed and applied Characteristics Nu-Klad 114A is a 100% solids epoxy filler compound to fill holes, voids en surface discontinuities in concrete up to ± 20mm across as measured in the largest dimension. A single application will fill or seal most air pockets and holes. On concrete block surfaces, Nu-Klad 114A provides a smooth surface for applying coatings or Nu-Klad 100A spray-on epoxy cladding.
It is applied in nuclear facilities, fossil fuel plants, sewage and waste treatment plants, food and beverage plants, chemical processing plants, pulp and paper mills, textile mills, steel mills, and mining and metal finishing operations.

Coating performance, in general, is proportional to the degree of surface preparation. Prior to coating, all surfaces must be clean, undamaged, dry and free of all contaminants, including salt deposits. STEEL - Prepare surface in accordance with Application Instructions for specific primer being used. Concrete must cure a minimum of 14 days and must have attained 80 percent of its physical properties before application of Nu-Klad 114A. Formed surfaces (verticals and overheads) must be adequately vibrated to minimize air bubbles and holes. Select a form facing material which will produce a smooth, hard uniform texture on the concrete. Do not use form release agents, such as form oils, that will deposit a residue on the concrete surface. Use only film forming release agents that will not impart residues onto the surface. Repair all defects. All fins and projections must be completely removed. Air blast formed surfaces using high pressure 7 kg/cm² compressed air to open air bubbles or holes crusted over with a thin laitence layer. High pressure air line must be equipped with operating oil and moisture separators.
Apply Nu-Klad 114A epoxy filler compound to the surface using a short nap paint roller or trowel. Spread and work the filler compound across the surface filling the voids using a floor trowel or wide bladed putty knife. Continue working the filler compound across the surface, applying pressure to achieve a smooth finish. Leave only a slight film above the surface plane. The filler compound should appear somewhat transparent allowing the concrete surface or concrete block texture to remain visible. A single application will provide a suitable surface to receive Nu-Klad 100A epoxy surfacing or for application of a coating over concrete block. For complete filling and sealing of formed concrete surfaces to receive Amercoat protective coatings, a second application may be required. Allow overnight curing at 20°C/68ºF, or until first application is set. Do not exceed three days at 20°C/68ºF before the second application. When making second application, use only reasonable pressure to build the film thickness to approximately 125 to 250 µm above the surface plane, and at the same time remove ridges left during spreading of the filler compound by the application tool. Repair all holidays with Nu-Klad 114A before applying coating.
Like all high performance coatings, Nu-Klad 114A must be applied as recommended to obtain the maximum protection for which this product is formulated. If conditions exist that are not within the requirements or limitations described, consult your PPG representative. Application Data Substrate ........................... concrete, steel, masonry Application methods ......... squeegee, roller, trowel, spatula Environmental Conditions Optimum material and surface temperatures are between 18 and 27°C (64 and 81°F). Store material within this range prior to use. Below 18°C/64ºF workability is reduced and application more difficult. Above 27°C/81ºF the working time decreases. Nu-Klad 114A can be applied to surfaces that are as low as 10°C/50ºF; although curing will be retarded, typical properties of the cured Nu-Klad will not be affected. Application under direct sunlight and rising surface temperatures can result in bubbling of the filler compound due to release of air or moisture from the concrete. Shade concrete that has been exposed to direct sunlight for 24 hours prior to application of Nu-Klad 114A, and keep shaded until after initial set has taken place. Where surface temperatures are rising, it may be necessary to postpone application. Potlife (at 20°C/68ºF) ........ 2½ hours (ASTM C308) Potlife is dependent on temperature and quantities mixed. Initial setting time (at 20°C/68ºF) 18 hours (ASTM C308) Drying times (at 20°C/68ºF)(before topcoating) minimum ........................ 18 hours maximum with Nu-Klad 114A ................. 72 hours Nu-Klad 100A ................. 168 hours If maximum recoat time has been exceeded, roughen surfaces.

For solvent containing epoxy coatings the minimum curing time for Nu-Klad 114A is 18 hours and the maximum curing time is 6 months. For solvent free epoxy materials such as Nu-Klad 100 A the minimum curing time is 18 hours and the maximum curing time is 7 days for indoor exposure and 3 days for Nu-Klad 114A which has cured outdoors. If maximum time is exceeded the surfaces must be roughened by abrasive blasting or mechanical means.
Shelf life : ...................... 1 year from shipment date when stored indoors in unopened, original containers at 5 to 40°C (41 to 104°F).
Immediately after use, clean all mixing equipment and application tools with Amercoat 12.
