PAINTING AND RECOATING Parex USA Finishes are generally beautiful for many years of service. However, if desired, Parex USA acrylic finishes can be recoated with Parex USA DPR Coating or Elastomeric Coating. Coatings will change the texture and shine of the original finish. Recoat Gel is not meant to change the texture. This is especially crucial to consider if the coating will cover existing sand or sand fine finish. Some of the texture in these finishes may be lost due to the aggregate size. It is advised that a physical sample be utilized to match the color of an existing Parex USA finish because existing aged finishes may have changed significantly from the original hue.

The existing finish should be clean and dry. Parex USA Coatings can be applied with a brush, roller, or suitable spray equipment (follow the product data sheet for application). In general, coatings provide high surface coverage in single applications over existing finishes. However, depending on the texture and/or color of the current finish, it may be necessary to apply two coats. When using a roller, apply the coating in vertical strokes, overlapping each stroke by half a roller width. For two coats, apply the first coat in horizontal passes and allow to dry. The second coat should be applied at a right angle to the first coat in the same manner as a single application.

RESURFACING AND REFINISHING If the finish material must be closely color matched to the existing work, a physical sample should be submitted to the Parex USA Color Department for analysis and matching. Even so, the new finish may appear slightly different than the original finish due to age or a change in the texturing technique of the applicators. If a wall surface must be resurfaced, it may produce a more acceptable appearance to resurface a panel or larger section to an existing break or termination rather than a smaller patch area.

According to Patching and Repairing, refinishing should be left to an applicator with prior experience with Parex USA Materials. The area must first be cleansed using one of the ways indicated above. Second, on the clean and dry existing finish, a skim coat of Parex USA base coat (Cementitious/Acrylic type) should be troweled onto the surface with a stainless steel trowel to a consistent thickness to entirely fill the voids caused by the original texture. If increased impact resistance is desired or reinforcing mesh is required to repair additional places, embed reinforcing mesh if specified into the wet base coat using installation instructions from the Parex USA EIFS application Guide. If primer was used on the previous job, use Parex USA Primer to increase the color consistency and trowelability of the new finish.

Follow the instructions in the Parex USA Product Data Sheet for the precise finish and texture desired while applying the new finish. Flashing and Sealants The first sign of water entering the building should highlight a problem, which should be addressed as quickly as feasible. EIFS systems, like other wall claddings, rely on flashing and sealants to prevent moisture from entering behind the face of the cladding.

As a result, it’s a good idea to inspect the installation at these crucial points on a regular basis:

  • Window and door frames.
  • Expansion joints
  • Abutments to different materials
  • Penetrations, such as those surrounding fixtures, hose bibs, outlets, scuppers, and so on.
  • Top and bottom wall terminations
  • Intersections of the sidewalls with the roof line Repairs to sealant joints may necessitate their removal and replacement.
