1 L tub of NeutralySalt Primer, a clear anti-salt treatment for walls with salt efflorescence, by Humix Paint

Para qué sirve

Stop salts crystallising on the surface.

A clear liquid treatment applied before painting on mineral walls with salts. It stops soluble salts migrating and crystallising at the surface, without affecting how the wall breathes. It holds back salt bloom, but it doesn't stop damp rising from the ground.

  • Acts on salts

    Chelating action on nitrates, chlorides and sulphates, the salts that form the white powder.

  • Lets the wall breathe

    Doesn't affect how the surface breathes.

  • Solvent-free

    Free of solvents. For mineral walls: lime, clay, brick, stone and renders.

  • Neat, no mixing

    Applied as it comes, with a brush, roller or sprayer.

Dónde se aplica

  • Lime and clay
  • Ceramic brick
  • Natural stone
  • Mineral renders
  • Mineral stuccos

Para qué no

Not for synthetic or varnished surfaces.

Primero, la causa. NeutralySalt holds back salt bloom at the surface, but it doesn't stop water rising from the ground. If the wall stays damp or the stain grows, rising damp has to be treated first.

Composition

What's inside

According to its technical data sheet:

  1. 1
    GLDA chelating agent

    Binds to soluble salts and holds back their crystallisation at the surface.

  2. 2
    Solvent-free

    Free of solvents and synthetic additives. Neutral odour.

In the box: the sealed container in the size you choose (1 L or 5 L).

How to apply it

5 steps, in this order

Important. Avoid contact with the eyes; if it happens, rinse with plenty of water. May be corrosive to metals: keep it only in its original container. Do not expose to temperatures below 0 °C.

  1. Step 1: Remove loose salt

    Scrape off salt crusts by hand and brush away the white powder. Leave the surface free of dust, grease, mould and loose material.

    • Time: 30 min
    • Tools: Stiff brush

  2. Step 2: Shake the container

    Use it neat, without diluting or mixing it with anything.

    • Time: 1 min

  3. Step 3: Apply 1 or 2 coats

    With a brush, roller or sprayer, wet on wet depending on how absorbent the wall is. Don't rinse afterwards.

    • Time: Depends on the area
    • Tools: Brush, roller or sprayer

  4. Step 4: Wait 24 hours

    At least, before any render or finish. Drying can vary with temperature and humidity.

    • Time: 24 h

  5. Step 5: Finish

    If the wall had algae or mould, one coat of Sellador Total L44 before the finish. If not, straight on with the finish (for example, MATE5000).

    • Time: After 24 h
    • Tools: MATE5000
