We’ve reached the last industrial design finish under the Konstrukt Lunar Series—the Kohl Finish.

As a recap, this series features 9 different decorative finishes that can all be achieved by using standard Konstrukt products. Yes, while Konstrukt is known for its surface preparation materials, the same items can actually also be used as a decorative finish on your walls. If you haven’t caught up on the previous posts yet, you can read about them all here.

The Kohl finish is the finer-textured cousin of the Kanyon finish. They pretty much have the same application procedure. The only difference is that for the Kohl finish, you should spray the product on thinly to achieve a more subdued, or less textured, finish.

This look can be applied to both interior and exterior spaces. Its subtle grainy texture makes it a unique alternative to normal latex paint. Pair the finish with striking furniture because this backdrop can really highlight the feature piece.

Like the other Konstrukt Lunar Series designs, it’s best to have a professional create this look in your home.

The Project Checklist

To recreate this look, you’ll need the following products:

  1. Konstrukt Permaplast K-202 High-Performance Acrylic Render
  2. Ordinary Portland Cement

To protect your finish, you have the following options:

  1. Boysen Acrytex Sealer B-1708
  2. Boysen Matte Shield B-4600
  3. Any Boysen water-based primer for concrete

Aside from the usual items like rags and tools like ladders, you’ll need these as well:

Prepping the Surface

Always prep the surface properly before starting on any renovation project. This saves you from a lot of headaches. Remove any honeycomb and loose concrete. Check and repair all surface defects such as cracks or gaps with corrective civil works. Waterproof as necessary. Dust off any dirt and make sure that the surface is dry. Check your weather app and do this project when the weather is nice and sunny. It helps the product’s cure time and is good for ventilation during the renovation. Take note that these products should only be applied over bare concrete.

Level the Concrete Walls

Stir Konstrukt Permaplast K-202 High-Performance Acrylic Render using a mechanical mixing device to obtain proper consistency. Transfer the mixture into a clean container and mix in Portland cement at a 1:1 ratio using the mixing device until it’s free from any clumps.

 Apply a thin layer of the mixture on the surface by pressing the edge of the steel trowel firmly on the concrete until all areas are covered. The applied mixture should be between 3mm to 5mm thick. Let it dry for at least half an hour before the spray application of the fine-textured finish.

Apply the Textured Finish

Use a mixing device to blend another batch of Konstrukt Permaplast K-202 High-Performance Acrylic Render until it’s lump-free. Transfer the mixture into another clean container and mix in Ordinary Portland cement using the mixing device until it becomes sprayable in consistency. Spray the mixture on the substrate by using a mortar gun until you get the fine texture that you want. Let the whole system cure for at least 7 days before applying anything else onto the substrate.

Protect your Kohl Finish

You can paint over the Kohl finish if you want a pop of color in your space. Just brush over a coat of any water-based primer like Boysen Permacoat Flat Latex B-701 and 2 coats of latex paint such as Permacoat, Healthy Home, or Virtuoso, depending on whether the finish is inside or outside your home.

However, if you want to maintain the bare cement color of the Kohl finish, just brush over a coat of Boysen Acrytex Sealer B-1708 on the design. Let the sealer dry for at least 2 hours then apply 2 coats of Boysen Matte Shield B-4600 to give it a low-luster finish.

We get it, Konstrukt Lunar Series can seem complicated. If you have any further questions on how to achieve this look, our in-house Konstrukt team will do their best to assist you. Just send us an email at ask@myboysen.com and we’ll let them know!
