MADRAS - SIGILLATERRAZZI Kit + Concentrated Buffered Acid | Terrace and Balcony Waterproofing | Cleaning and Protection
Clean, seal, and protect in a single professional kit. The MADRAS SIGILLATERRAZZI Kit + Concentrated Buffered Acid combines the two essential products for the complete treatment of balconies, terraces, and suspended floors: first, limescale and efflorescence are removed with the Inhibited Concentrated Buffered Acid (safe, fume-free), then the surface is deeply waterproofed with SIGILLATERRAZZI, a solution based on silanes, siloxanes, and organic polymers that seals macroporosity and cracks up to 1 mm, eliminating water infiltration.
- Product 1: SIGILLATERRAZZI — deep-penetrating water-repellent waterproofing agent
- Product 2: Concentrated Buffered Acid — anti-efflorescence and anti-limescale cleaner
- SIGILLATERRAZZI chemical base: silanes, siloxanes, and organic polymers in dearomatized solvents
- Treatable cracks: up to 1 mm
- Acid: inhibited, fume-free, with a slowed reaction
- Applications: balconies, terraces, suspended floors, indoor and outdoor floors
- SKU: 1SGT1X12+1AT2X12
- EAN: 8022939665107
Product 1 — SIGILLATERRAZZI: Deep-Penetrating Water-Repellent Waterproofing Agent
- Formula based on silanes, siloxanes, and organic polymers: penetrates deep into the porous structure of the material, creating a long-lasting water-repellent barrier from within
- Seals macroporosity and cracks up to 1 mm: eliminates water infiltration routes without altering the surface's appearance
- Dearomatized solvents: low environmental and olfactory impact formulation compared to traditional products based on aromatic solvents
- Deep waterproofing: does not form a surface film prone to peeling, but consolidates the material from within
- Ideal for balconies and suspended terraces: protects the underlying structures from infiltration and moisture damage
Product 2 — MADRAS Concentrated Buffered Acid: Anti-Efflorescence and Anti-Limescale Cleaner
- Inhibited and buffered acid: does not produce irritating fumes, safe to use in enclosed and semi-enclosed spaces compared to common muriatic acid
- Slowed reaction: greater control during application, reduces the risk of damage to adjacent surfaces
- Removes efflorescence and limescale: essential for cleaning the floor before any protective or waterproofing treatment
- Replaces common muriatic acid: same effectiveness with greater safety for the operator
- Suitable for ordinary and extraordinary cleaning: for preparing the substrate before treatment with SIGILLATERRAZZI and other MADRAS products
- Never use undiluted: always dilute according to the manufacturer's instructions before use
