Stain-Resistant Masonry Sealer

Resistain – brushed on in 30 minutes, stain-resistant for 15 years.

Resistain is a stain-resistant penetrating sealer for masonry materials.
It is a highly-advanced solvent that penetrates into masonry surfaces and renders them oil- and water-repellent. Resistain is optimised for use on all types of masonry surfaces, both indoors and outdoors, to reduce all forms of surface degradation.

Resistain provides excellent, hard-wearing resistance against staining liquids including oil, juice, coffee, ink and wine, whilst also protecting the treated surface from the effects of water exposure, including:
- Efflorescence
- Erosion and friability
- Mould
- Algae growth
- Concrete cancer
- Internal rebar corrosion.
The treatment will not change the appearance or texture of the surface and the surface will remain breathable.

You Will Need

Low pressure spray (ideal), or a clean brush or roller with tray

1L of Resistain covers 5 to 30m² depending on porosity of surface

Dry cloth to wipe excess Resistain

Preparation: Clean and repair the surface

The surface to be treated should be dry, firm and free from grime, oil and any previous coatings/sealers. All cracks should be filled and allowed to cure before application.

Application: Apply Resistain

  1. Use a low pressure spray or brush to evenly coat the surface with Resistain. The initial treated surface should have a mirror-like wet film appearance.
  2. After the first coat is absorbed by the surface or the surface becomes touch dry, apply the second coat.
  3. After ten minutes, wipe up any liquid that remains on the surface to ensure an even finish.

Two coats are enough for general substrates but more coatings may be required for very porous substrates.

After Application

The initial surface oil and water repellency will develop after the surface is completely dry. Full curing may take 24 hours or more. Avoid heavy traffic for 24 hours. The equipment can be washed in isopropanol or mineral turpentine.

Important Tips

  • Do not apply if adverse weather conditions are expected.
  • A test prior to application is strongly recommended to assess the suitability of the product to the purpose.
  • For smooth/polished surfaces, it may be necessary to polish the surface with a clean and white cloth to remove excess sealer residue to reveal the original surface finish. This may be done after surface becomes touch dry or within a few hours after application.
  • Moistening the cloth with Resistain may help to ease the polishing.
