RFP Title


Interior Coatings that Enable DIY Wall Restoration
RFP Description

NineSigma, representing a Global Consumer Coatings Company, invites proposals for materials and coatings formulations that behave as both a pre-treatment for minor defects, and as a primer base for a topcoat, in an interior wall paint.

The ideal solution would allow for a consumer-grade paint product to repair and smooth shallow scratches, nail holes, and other minor defects in an interior wall surface without having to apply a skim coat, spackling, or other pre-coating treatment.

The client is interested in approaches that allow for a product that can be brushed or rolled onto the wall surface, or otherwise applied using standard consumer-based painting implements (e.g. the resulting formulation will not require professional-grade or special application mechanisms).

The solution should also smooth out patchy, inconsistent light texture. Final finish after application should be a smooth (highly preferred) or very slightly textured (less preferred) uniform surface and require no post application treatment such as trowel finishing or sanding.

The repaired surface should be white or near-white and provide a primer base for top coating using common acrylic/latex paints. Light stain blocking of underlying household stains is a plus.

Solution providers should expect that typical cleaning preparation required for priming interior walls has been carried out by the DIY homeowner. The end-user has cleaned the damaged wall and it is free of dust, grease, wax, peeling paint, mold, mildew and wallpaper paste. If cleaning was executed, a non-soapy detergent or a TSP substitute was used, and the wall was rinsed well and allowed to dry. In addition, all loose paint and debris has been removed from the surface. If the starting surface was glossy, the user scuff-sanded and cleaned the surface prior to the application of the product.


Home buyers frequently buy older homes that need improvement and updating. The interior walls of these older homes often have multiple minor but unsightly dings, cracks, holes, and patchy, inconsistent surface appearances resulting from multiple prior repairs.

The new homeowners face the daunting task of restoring the interior wall to uniform appearance and frequently cannot afford professional wall restoration. At the same time, taking on a DIY wall restoration project can be very intimidating to the homeowners because of the time, experience, and skill required to make the repairs. Rehanging and finishing new drywall is not an option for the majority of these DIYers. Using a trowel to skim coat an entire wall with drywall plaster and then finishing by sanding the entire wall is often beyond the DIY owner’s ability or interest.

If untreated, a painted interior wall surface will reveal flaws such as nail holes, small cracks, scratches, and other imperfections. Paints and coatings may be able to fill small dents and holes, but upon curing, the receding surface will pull the coating formulation into its contours.

A simple and fast coating solution is needed that an inexperienced DIY homeowner can use to create a uniform finish on lightly damaged, previously painted home interior vertical drywall (plaster board/gypsum board) or plaster surfaces.

Key Success Criteria

The technology must:

  • Effectively eliminate the need for the consumer to prepare (by sanding, skim coating, nail patching, etc.) the surface to be painted. Please refer to the description, above, for more details.
  • Allow for surface preparation in one step, effectively eliminating visual contours once the product has completely cured.
    • The formulation must be able to smooth and fill minor scratches, uneven surfaces, nail holes, and small cracks.
    • The solution surface should require no post-application treatment such as sanding. The result should allow for the consumer to apply a topcoat or finish using common acrylic/latex interior paints.
  • Preferably not contain any compounds or agents that are toxic or hazardous for a typical interior consumer coating. The solution should have low VOC content (< 50 g/L).
  • In no more than two coats, the solution should repair hairline cracks up to 1/8” wide (3.2 mm) without cracking afterward and cover holes up to ¼” diameter (6.4 mm) without requiring prefilling of the cracks and holes.
  • Allow for the DIY user to apply the solution with a conventional paint roller and brush. The user should be able to apply two coats and be ready for top coating in 8 hours.
Possible Approaches

Possible approaches might include, but are not limited to:

  • Mechanisms, additives, or agents that enable a ‘thickening’ effect, or enable material expansion, to a liquid coating, after application/curing
  • Novel adhesives formulations or agents
  • Novel agents or additives to provide structure to a liquid coating matrix
  • Rheologic materials solutions, thixotropic liquid innovations
  • Advances in self-healing materials solutions and technologies, particularly those that can be incorporated into a liquid coating formulation
Approaches not of Interest

The following approaches are not of interest:

  • Water-based acrylics, or formulations for water-based acrylics unless the proposed approach is truly unique
  • Products that are formulated for professional use (e.g. require special handling)
Items to be Submitted

Your response should address the following:

  • Non-confidential description of proposed technology and working principle
  • Availability of technical data or evidence to support your approach, and its ability to address the key points listed in this RFP
  • Technical maturity of the approach (concept, reduced to practice, prototype, ready to commercialize, ready to implement, commercialized)
  • Pathway to commercial scale including timing, estimated budget, and capacity for manufacture
  • Position on intellectual property including patent references
  • Desired relationship with sponsor
  • Team description and related experience
