Common Application Techniques

A step-by-step guide to preparing the wood surface

Use Exterior Wood Cleaner to clean wooden patios, fences, exterior doors, and carports before it is finished with a Rubio Monocoat exterior finish product. The cleaner removes grey discoloration, green deposits, and dirt. 

Application methods: hand application vs. machine application

Hand application involves mixing Part A and B components with a ratio of 3:1 of Part A to Part B. Clean the surface and let it dry. Spread out a small quantity of Oil Plus 2C with a Rubio Monocoat Scrubby Pad and let the oil absorb for a few minutes. Remove excess with Rubio Monocoat White Rags within 15 minutes per zone. When it comes to machine application, use a Rubio Monocoat white machine application pad with a diameter of 150 mm. Synthetic fibers are for the effective wiping and polishing of oils. 

The hand application method is straightforward and does not require the craftsman’s skills for professionally brushing or spraying a wood finish. Large electric floor buffers can also be used for the application process. Hand application is ideal for smaller projects. Larger surfaces require a smaller electric tool like a random orbit sander, small buffer, or a roller application.

Tips for achieving consistent and smooth results

  • For a sheen finish, sand to high grits before application or buffing afterward.
  • Give a final buff with a lint-free cloth.
  • Work in sections that allow you to apply the oil and remove the excess within 15 minutes.
  • Prepare the surface to achieve the desired result.

Exploring Rubio Monocoat Problems

A. Uneven Coloration and Streaking

Factors contributing to uneven coloring

  • Unequal sanding
  • Failure to remove excess oil
  • Failure to mix the finish well
  • Different patterns in the wood

Prevention and techniques for achieving even color distribution

  • Remove excess oil before drying
  • Mix well
  • Do not over-sand
  • Work along the grain

B. Adhesion Issues

Understanding reasons behind poor adhesion

The type of adhesive should be suitable for the application. Be aware of unexpected environmental changes that can cause the adhesive to fail. Heat, cold, and moisture affect adhesion. 

Proper wood surface preparation to enhance adhesion

Preparing wood surfaces for adhesives requires pretreatment. Dry the wood first before pretreatment. Dust, dirt, oil, and grease can contaminate your surface. Using alcohol will dissolve light grease and water, removing dirt and accumulated dust. Make sure the surface is dry before applying the adhesive.

C. Drying and Curing Challenges

Causes of prolonged drying and curing times

  • Cool temperatures
  • Higher relative humidity levels
  • Poor airflow

Temperature and humidity management for optimal results

Rubio monocoat is ideal for use in rooms with high humidity, such as bathrooms and kitchens. The wood surface must be dry and clean. Maximum moisture content should be 12 %.

D. Overcoming Application Imperfections

Dealing with drips, runs, and excess product

Apply the finish onto the dry area, leave it to react for 3-5 minutes, then wipe dry, removing all excess. Go over the whole surface and equalize the color and change pads. Spread it across the floor and penetrate the wood as it is buffed in.

Techniques for rectifying application mistakes

For small scratches, apply a small amount of oil onto the damaged area, and rub with a scotch pad or cloth. Leave for a minute and wipe any excess off with a dry cloth. For deep scratches, sand to remove the bulk of the scratch and apply two coats when sanding back to the bare wood surface. 

Addressing Long-Term Durability

Discussion on Rubio’s mono coat’s durability over time

A wood surface finished with Rubio Monocoat’s hard wax oil can last longer when cared for properly. Rubio Monocoat can withstand spills without leaving a stain or etching in the finish.

Protective measures to enhance product longevity

Remove any grit or dust by using an electrostatic dust mop. Clean the surface with a lint-free cloth, using minimal water on the surface. Look after your floor with the correct maintenance products. Hardwax oil floors will last longer and be easy to maintain.

Compatibility with Different Wood Types

Impact of wood species and grain on application results

The effects of wood types and grain direction of the grain angle determine your application results. It helps improve strength by cutting along the grain rather than against it. Choosing the correct grain direction gives smoother cuts.

Tailoring application techniques to specific wood characteristics

Finishes beautify wood by deepening its color and highlighting its grain patterns. Rubio monocoat protects the wood by controlling the rate at which moisture transfer takes place.

Comparing Rubio Monocoat to Alternative Finishes

Analysis of Rubio Monocoat vs. traditional polyurethane, varnish, and oils

Monocoat can fix small scratches and other wear and tear without refinishing the entire floor. A polyurethane floor looks best on the day it is refinished. Rubio monocoat does not add the familiar shine of polyurethane finishes and does not look as good the day it is applied. Over time, Rubio will become apparent as the natural beauty of the wood comes through.
