Hard bottoms

Hard bottoms

The term hard bottoms refers to a product used specifically for the preparation of wooden floors prior to the application of a finish, such as vitrification or oiling.

The hard sealer is designed to penetrate the wood fibres, strengthening its structure and making it more resistant. It also helps to limit excessive absorption of subsequent finishes, promoting better adhesion and even distribution of the finishing product over the floor surface.

Often used for :

1. Block rising tannins: Some types of wood contain natural tannins that can cause stains or undesirable chemical reactions with the finish. The hard sealer effectively blocks these rising tannins, preventing potential problems.

2. Uniform absorption: The hard sealer regulates the absorption of the wood, allowing the finish to be better distributed over the surface of the floor. This helps to avoid variations in absorption that could lead to differences in colour or gloss after the finish has been applied.

3. Reinforce the resistance of the wood: By penetrating the wood fibres, the hard sealer reinforces the structure of the floor, making it more durable and resistant to knocks, wear and stains.

It should be noted that the specifics of the hard sealer may vary depending on the specific product. It is therefore advisable to refer to the manufacturer's instructions for use and recommendations for the most precise information on the use of the hard sealer.

4 Water-repellent properties: Some hardbeds may have water-repellent properties, forming a protective barrier against rising damp and thus protecting the floor from the effect of water.
