Uses
The high elasticity, excellent bond and low water permeability of RAK Proof-FB makes it ideal for a wide range of water/vapour proofing applications such as foundations, basements, tunnels, ground floors, suspended floors, car decks, roof terraces, balconies, patios, bridges, precincts, inspection pits, water retaining structures( not potable water), sewage works, inverted roofs , toilets, bathrooms, kitchens etc. The excellent chemical resistance of RAK Proof-FB makes it particularly suitable for tanking applications in areas where agressive ground water conditions prevail.
Shelf Life
Must be protected between 5°C and 30°C. 12 months in unopened airtight containers.
Cleaning
Clean all tools with water after use.
Application
The support must be clean, free of dust, dirt, oil, grease and loose particles. When applying on metal surfaces,remove rust and contamination for best results. Apply with brush, roller or an approximate spray. Apply a primer coat of RAK Proof-FB (80% RAK Proof-FB + 20% water) with brush, roller or spray. Once the primer coat has completely dried, apply minimum two coats of undiluted RAK Proof-FB. It is important to ensure that coat has totally cured(i.e-min 6 hours at 30°C).
Health & Safety
As with all chemical products, caution should always be exercised. Protective clothing such as gloves and googles should be worn (see packaging for specific instructions). Treat any splashes to the skin or eyes with fresh water immediately. Should any of the products be accidently swallowed do not inducce vomiting, but call for medical assistance instructions and content details.Reseal all containers after use and ensure product is stored as instructed on the safety section of the labelling immediately.
