Description

Osmo End Grain sealer protects the ends of decking and other wood types. Ideal for interior and exterior use as it has excellent weather, water and dirt resistance which minimises swelling and shrinkage whilst protecting against cracks and preventing bleeding. This clear sealer has a microporous formulation which gives a breathable finish that does not peel, flake or crack. Safe for human, animal and plant once dry.

 

Key Features

  • Protects edge grain of decking against cracks
  • Prevents wood ingredients from bleeding
  • High weather resistance
  • Safe for human, animal and plant once dry
  • Very water and dirt resistant
  • Minimises wood swelling and shrinkage
  • Microporous, breathable finish which does not crack, peel or flake
  • Suitable for interior and exterior use

 

Application 

SURFACE PREPARATION

Wood surface must be clean, dry and frost-free (moisture content max. 20%).
Osmo End Grain Sealing Wax is ready to use. Do not thin. Stir well.
The finished surface is influenced by several factors, including the condition of wood. Therefore, a trial application is always required, especially for unfamiliar surfaces.

METHOD OF APPLICATION

With Osmo Flat Brush, apply generously to end grains.
To achieve an optimal protection for strongly absorbing end grains, we recommend applying the sealing wax two times wet-in-wet or after drying carry out a second coat.

NOTE

Osmo End Grain Sealing Wax is clear and therefore it can be applied universally.
Please only apply to end grains. Not for area treatment. Wipe away any excess wax from other surfaces with a cloth.
Oils enhance the natural tone of wood (permanent wet effect). After drying, we recommend coating the other wood surfaces with Osmo wood finishes (e.g. Bangkirai-Oil, Massaranduba-Oil, Country Colour or Natural Oil Woodstain).

Using power washers will severely decrease the coverage of the finish and general or multi-purpose cleaners will increase the frequency of maintenance and recoating.

OVERVIEW

Osmo End Grain Sealing Wax protects the end grain from cracks during all elements of weathering. Minimises the water absorption, as well as the seasoning of the end grains. The surface is water and dirt resistant. Swelling and shrinking as well as ‘bleeding’ of the contents of the wood will be reduced. It is clear and is therefore universally applicable.


FAQs

1. What is Osmo End Grain Sealing Wax?

Osmo End Grain Sealing Wax is a clear wood finish specifically formulated to protect the end grains of timber from weather-induced cracks and moisture ingress. It enhances the wood's durability by minimizing swelling, shrinkage, and the leaching of natural extractives.

2. What are the key benefits of using this product?

  • Crack Prevention: Protects end grains from cracking due to weather exposure.
  • Moisture Resistance: Reduces water absorption, decreasing the likelihood of swelling and shrinkage.
  • Dirt Resistance: Creates a surface that resists dirt accumulation.
  • Breathable Finish: Provides a microporous, breathable layer that prevents peeling, cracking, or flaking.
  • Universal Application: Suitable for both interior and exterior use on various wood types. OSMOUK

3. On which types of wood can I use Osmo End Grain Sealing Wax?

This sealing wax is ideal for both hardwoods and softwoods, including:

  • Bangkirai
  • Teak
  • Massaranduba
  • Garapa
  • Cumaru
  • Pine
  • Spruce
  • Douglas Fir
  • Larch
  • Cedar
  • Thermowood

It's particularly effective for end grains of decking, cladding, and roof soffits.

4. How do I apply Osmo End Grain Sealing Wax?

  • Surface Preparation: Ensure the wood surface is clean, dry, and free from frost, with a maximum moisture content of 20%.
  • Application: Stir the product well before use. Using an Osmo Flat Brush or a lint-free cloth, generously apply the sealing wax to the end grains.
  • Multiple Coats: For optimal protection on highly absorbent end grains, apply two coats wet-on-wet or allow the first coat to dry before applying the second.
  • Drying Time: Under normal climatic conditions (23°C and 50% relative humidity), the drying time is approximately 3-4 hours. Lower temperatures or higher humidity may extend the drying period. OSMOUK

5. Can I use this product on surfaces other than end grains?

Osmo End Grain Sealing Wax is specifically designed for application on end grains. It is not intended for broad surface treatments. Any excess product on other surfaces should be wiped away promptly with a cloth.

6. Is it safe for use around humans, animals, and plants?

Once dry, the product is safe for humans, animals, and plants, making it suitable for various environments.

7. How should I maintain surfaces treated with Osmo End Grain Sealing Wax?

  • Regular Cleaning: Use a damp cloth or mop with Osmo Decking Cleaner and the Osmo Decking Cleaning Brush for routine maintenance.
  • Intensive Cleaning: For deeper cleaning, consider using Osmo Wood Reviver Power Gel or Osmo Gard Clean as needed.
  • Reapplication: When signs of wear become visible, simply reapply one coat to the clean and dry end grain surface. OSMOUK

8. What coverage can I expect from a 375ml can?

A 375ml can covers approximately 250 decking boards, treating both ends. Coverage may vary based on wood type and condition.

9. How should I store Osmo End Grain Sealing Wax?

Store the can in a dry place with the lid tightly closed. If the product thickens due to frost, keep it at room temperature for 24-36 hours before use.
