Rubio Monocoat adds color and protection to your wood surface. It gives wood an improved look and feel. Thanks to its natural ingredients that form a molecular reaction with the exposed cellulose fibers of the wood, you get an even finish and easy application. We have compiled a guide on the application, effect, care, advantages and disadvantages.

Understanding the Application Process: how to apply rubio monocoat

A. Preparing the Surface

Choosing the right type of wood for Rubio Monocoat

Rubio works on fir, pine, and conifers as they bond to the wood and resist solvents and abrasion. This is what it would be on any other wood floor. Apply to all wood types, including both hardwoods and softwoods.

Sanding the surface for optimal adhesion

Sanding is the first part of finishing a piece of wood. Use a random orbital sander, and sand each grit from 80 grit, then 100 grit, then 120 grit, then 150 grit, then 180 grit, then 220 grit till satisfied. Do not skip grits in between to avoid tiny swirls or pigtails. 

Each grit will remove the micro sanding marks left by the previous grit. Grit progressions will take time but give a superior finish when completed. The higher you sand your piece, the more the wood pores close. Sand to 120 grit. Going above can close off the pores. Sand through the grits to 180. The oil binds more effectively at lower grits. 

Cleaning and removing dust and debris

After completing the sanding task, remove all the dust before applying your finish. Wipe away all excess dust with a dry rag, using mineral spirits or denatured alcohol to wipe down the sanded surfaces ( Let the wood dry for an hour or two. Leave the sanded wood raw and free of any lint, dust, or debris that would prevent the Rubio MonoCoat finish from getting enough molecular adhesion to the wood.

Step-by-Step Application Guide

A. Applying the Rubio Monocoat

Explaining the one-coat application principle

This wood oil protects and colors in one layer. The wood protector of Rubio Monocoat protects against stains, water, and heat without multiple layers. Monocoat is a single-coat finish.

How to properly mix the Rubio Monocoat product

Mix Part A and B components with a ratio of 3:1 of Part A to Part B. Mix and stir thoroughly. When using multiple cans, mix all cans. Mixing is done using a scale, plastic syringes, measuring spoons, or measuring cups. 

Techniques for applying the coat evenly

  • Sand lightly
  • After sanding at 120 grit, lightly spray the sanded surfaces with clean water
  • Remove excess oil with a cloth
  • Spread evenly using a lint-free cloth

B. Massaging and Wiping

Importance of massaging the coat into the wood

Massaging the coat into the wood penetrates wood finishes, giving a more natural look as they enter deep into the surface of the wood. Use a rag to add a protective layer of wood oils to ensure better sheen and surface penetration. 

Using lint-free cloths for wiping off excess oil

Shake the wood oil before applying an amount to a clean, dry cloth. Allow 15 to 20 minutes to absorb and remove excess oil with a lint-free cloth. Leave the furniture to dry overnight. For better results, treat 2-4 times.

Achieving a uniform finish through careful wiping

For a uniform finish, sand the bare wood with a 100-grit sponge or paper. Allow it to penetrate for 5-15 minutes, then wipe away the excess with a cloth. 

C. Allowing for Curing

Understanding the curing process of Rubio Monocoat

After 48 hours, the oiled furniture is almost 80% cured. A full cure takes place within five days. Ensure there is enough ventilation. Do not use any liquids or clean them before it cures. It cures quickly since it contains an accelerant, hardener, oil, and color. The Rubio Monocoat sample sizes can take up to 3 weeks to fully cure since they contain part A, the oil, and color without part B, which is the accelerant and hardener.

Recommended curing time for different environments

Under typical application and drying conditions, you may be ready to use the floor after approximately 24-36 hours. After 48 hours, the oiled floor is 80% cured. A full cure takes place within five days.

Avoiding contact and disturbances during curing

When curing lumber, enough air circulation and ventilation are required. Moisture buildup affects drying, creating the perfect environment for insects to thrive. Optimal ventilation around the lumber piles is a must. Avoid drying faults such as over-stacking, not using stickers or inadequate airflow.

Achieving Different Effects with Rubio Monocoat

A. Creating a Deep Color Effect

Using pigments to enhance wood color

Staining wood with the same color of pigment stain and dye stain enhances color. The dyed portions will look much more similar than the ones not dyed. 

Techniques for achieving rich and dark hues

  • Use glaze as a toner on the sealed surface, resulting in a deep, rich color and a uniform appearance. 
  • Brush it on and wipe it off. 
  • Blend uneven areas by varying the glaze you leave on the surface.

Blending different shades for a unique look

Different colors enrich the natural look and feel of wood. These can be mixed, providing an unlimited palette of options.

B. Enhancing Natural Wood Grain

Applying Rubio Monocoat to highlight grain patterns

Rubio Monocoat can enhance and highlight the natural and distinctive wood grain patterns. Sanding to higher grits closes the grain and reduces the protection offered by the oil.

Techniques for emphasizing the natural beauty of wood

  • Clean using Rubio Monocoat Soap or Surface Care Spray, removing all dirt and grease without leaving a film.
  • Staining leaves wood naturally.
  • Use the hand wiping technique.

Tips for working with different wood types

  • Make sure their undertones match
  • Study different types of wood before you purchase the material for your project
  • Do not use more than three different woods

Maintenance and Longevity

A. Cleaning and Regular Upkeep

Gentle cleaning methods to maintain the finish

Dust it every week using a slightly damp microfiber or other soft cloth. Buff the surface dry. Do not over-use furniture polish, but buff with a soft cloth to bring up the shine on dull furniture. For the cleanest version of wood, wipe down with a damp microfiber towel and a drop of dish soap, or even scrub down with Clean-A-Finish for the worst pieces.

Applying maintenance oil to revitalize the coat

Apply the first coat of maintenance oil with a brush as it soaks immediately into the wood as soon as it is applied. Apply a thin coat, leave it to react for 3-5 minutes, then wipe dry. Remove all excess.

Handling minor scratches and blemishes

A 1:1 mixture of cooking oil and white vinegar removes scratches from wood furniture. Rub out surface scratches in your wooden furniture.

B. Longevity of Rubio Monocoat Finish
