El mejor quitamanchas y óxido del mundo (R&S)

El Mejor Quitamanchas y Óxido del Mundo (R&S) es una solución ácida tamponada, formulada por expertos para eliminar el óxido (óxido de hierro) y las manchas minerales de superficies de construcción, tanto porosas como no porosas. Este potente limpiador elimina eficazmente:

  • Fertilizantes, riego, agua de pozo o manchas de barro.
  • Manchas de ácido de batería
  • colorantes de calcio insolubles
  • Escorrentía de pintura oxidada de superficies porosas como hormigón y ladrillo

Características y beneficios:

  • Ecológico: Fórmula biodegradable y sin fosfatos.
  • Baja formación de espuma: diseñado para un enjuague fácil, dejando las superficies limpias sin residuos.
  • Limpieza potente: elimina eficazmente la grasa y la suciedad difíciles, garantizando resultados profesionales en todo momento.
  • Uso versátil: ideal para limpiar adoquines, maquinaria de hormigón, fábricas, restaurantes de comida rápida y cocinas.
  • Prepara superficies para pintar: limpia y desengrasa pisos de concreto manchados de aceite, dejándolos listos para pintar.

Instrucciones de uso del producto:

Para manchas de hormigón y ladrillo:

  1. Mezcle R&S Remover, generalmente en una dilución de 1 parte de agua por 2 partes de R&S Remover (se puede ajustar a una dilución de 1:1 hasta 1:4 según la gravedad de la mancha).
  2. Humedezca bien la superficie antes de aplicar.
  3. Aplique R&S Remover sobre la superficie húmeda usando un aerosol, cepillo o escoba, asegurándose de cubrir uniformemente el área afectada y las superficies circundantes.
  4. Deje actuar el producto hasta que la superficie se seque y luego enjuague con una hidrolavadora. Para manchas difíciles, repita el proceso según sea necesario.
  5. Nota: Las manchas profundas de óxido pueden hacerse visibles solo cuando están mojadas, así que deje que la superficie se seque antes de evaluar la eficacia del tratamiento.

Para superficies no porosas/no minerales (por ejemplo, paredes pintadas, estuco, vinilo):

  1. Primero enjuague la superficie con agua.
  2. Aplique la solución R&S sobre una superficie húmeda (que no gotee), generalmente diluida al menos 2:1, dependiendo de la gravedad de la mancha.
  3. No deje que el producto se seque. Enjuague bien una vez que la mancha haya desaparecido.

Pautas de cobertura:

Un galón de World's Best Rust and Stain Remover limpia aproximadamente de 250 a 800 pies cuadrados de concreto, dependiendo de la gravedad de la mancha, la dilución y la porosidad del sustrato.

Advertencia: Realice siempre una prueba en una zona pequeña antes de aplicarlo a gran escala. Este producto contiene ácido oxálico, que reacciona con el óxido de hierro para formar sales solubles en agua. Enjuague bien después de usar y considere frotar con un cepillo para obtener resultados óptimos. Para obtener los mejores resultados, rocíe ligeramente de la junta de control a la junta en lugar de concentrarse solo en el área manchada.
