Sovereign SX70 Reviver

Health & Safety Recommendations

When handling and applying Sovereign SX70 Reviver, appropriate Personal Protective Equipment (PPE) should be worn, including gloves, goggles, and a suitable mask when sanding. Avoid inhaling fumes and ensure adequate ventilation during application and drying. Keep away from open flames, heat sources, and direct sunlight.

Children and animals must be kept away from the treatment area until the product has dried completely. Always read the product label and consult the Material Safety Data Sheet (MSDS) before use.

Substrate Suitability

Sovereign SX70 Reviver is specifically designed for application over previously coated timber that has been treated with Sovereign SX70 Wood Stain. It is suitable for both interior and exterior wood surfaces, providing additional protection while enhancing the sheen of the stained wood.

The timber must have a moisture content of less than 18% to ensure optimal adhesion and performance. This product is not suitable for use on decking, as it is not designed to withstand heavy foot traffic.

Surface Preparation

All surfaces must be sound, clean, and dry before application. Any dirt, grease, loose paint, or other surface contaminants must be removed to allow proper adhesion. If applying to timber that has been recently coated with Sovereign SX70 Wood Stain, ensure that the stain has been allowed to dry for a minimum of 24 hours. If more than 72 hours have passed, lightly sand the surface with inter-coat sandpaper before application to promote adhesion. When sanding, a face mask should be worn to prevent inhalation of dust particles.

For previously stained but weathered timber, thoroughly clean the surface and allow it to dry before applying SX70 Reviver. Any mould or algae growth should be treated with Green Gone Moss & Algae Cleaner, ensuring all growths are removed before the wood is left to dry. It is essential to conduct a test patch in an inconspicuous area before full application. Allow 24 hours for the test area to dry and assess for any unwanted changes in appearance.

Application Method

Stir the product thoroughly before and during use to ensure uniform consistency. Do not use directly from the tin—decant a small amount into a separate container for application. Avoid returning any used product to the tin to prevent contamination.

SX70 Reviver should be applied using a high-quality wood stain brush, following the direction of the wood grain for the best finish. Apply with minimal brush strokes to achieve an even coat. End grains should be sealed, and special attention should be given to vulnerable areas such as the tops and bottoms of doors and the underside of sills. The backs of beads and rebates should also be coated to ensure full protection.

The first coat should be allowed to dry thoroughly before assessing whether a second coat is required. In optimal conditions, a second coat can be applied after 24 hours to achieve additional protection and a more pronounced sheen. Application should not be carried out in temperatures below +10°C, in damp conditions, or when rain is expected within the drying period.

Coverage

The coverage of Sovereign SX70 Reviver will depend on the substrate porosity and application technique. On average, it covers 10 to 12m² per litre per coat. Highly porous surfaces may require additional coats or heavier application.

Drying Time

Sovereign SX70 Reviver will be touch dry in 3 to 6 hours, depending on environmental conditions such as temperature and humidity. Full curing occurs within 24 hours, after which a second coat can be applied if necessary.

Cleaning

Immediately after application, clean brushes, tools, and equipment with white spirit to prevent hardening of any residual product. Remove as much product as possible before cleaning to minimise waste. Dispose of used materials and contaminated cleaning solutions in accordance with local environmental regulations.

Other Information

Sovereign SX70 Reviver is formulated to enhance the protection and longevity of SX70 Wood Stain and should not be used as a standalone coating. It is also not suitable for use directly over SX70 Basecoat, as it is designed to work in conjunction with a fully cured stain layer. Due to natural variations in timber composition, certain wood types may release solvent-soluble resins or water-soluble tannins, which can affect the final finish. If in doubt, a small test area should always be trialled before completing the full application.

For long-term storage, keep the product sealed in its original container in a cool, dry place at temperatures between +5°C and +25°C. Protect from frost and avoid prolonged exposure to heat. Proper storage conditions will maintain product performance and extend shelf life for up to 12 months from the date of manufacture.

Q) What is Sovereign SX70 Reviver used for?

A) Sovereign SX70 Reviver is a high-performance, solvent-based topcoat designed to restore and enhance timber surfaces that have been previously treated with Sovereign SX70 Wood Stains. Over time, exposure to UV radiation, moisture, and environmental conditions can cause wood stains to fade and deteriorate. This reviver replenishes the protective properties of the stain, reviving the appearance of the timber while providing an additional layer of defence against the elements. It delivers a semi-sheen finish that enhances durability without significantly altering the timber’s natural colour.

Q) How does Sovereign SX70 Reviver work?

A) Sovereign SX70 Reviver is formulated with a long oil alkyd resin base, which penetrates the wood surface to strengthen adhesion and provide long-lasting protection. It contains advanced UV inhibitors, preventing sun damage and fading, while its water-repellent properties help protect against moisture ingress, swelling, and rot. The inclusion of fungicidal additives also ensures resistance against mould, algae, and fungal growth, maintaining a clean and well-preserved finish.

Q) Can Sovereign SX70 Reviver be used on untreated timber?

A) No, Sovereign SX70 Reviver is specifically designed to be applied over previously stained timber that has been coated with Sovereign SX70 Wood Stain. It should not be used as a standalone wood treatment, as it relies on the existing stain layer to achieve optimal adhesion and performance. If treating bare timber, it should first be stained with Sovereign SX70 Wood Stain before applying the reviver.

Q) Is Sovereign SX70 Reviver suitable for both interior and exterior wood?

A) Yes, it is suitable for both interior and exterior applications, making it a versatile choice for doors, windows, cladding, fencing, garden furniture, and internal woodwork.
