2. TDS - WP - NF05 - 000_12/20 NEOSEAL FLEX CR is applied by brush or spray onto the dampened substrate. Apply the material in 2 coats at right angles; apply the second coat whilst the first is firm, but “green” – usually 3 - 4 hours after first coat (dependent on temperature). APPLICATION: Structures subject to water leakage or ingress must be carefully inspected to determine the cause. Any water present should be cleared away so that a thorough survey can be conducted. Static cracks over 1mm must be chased out, dampened down and repaired with a suitable cementitious repair mortar such as NEOCRETE FBR on a NEOSEAL FLEX CR slurry coat. Dynamic cracks must be formed into a watertight elastomeric movement joint. EXISTING STRUCTURES: As with all coating systems, surface preparation is of prime importance, the quality of substrate preparation directly affects the performance of the coatings. Surfaces to be treated must be free from dust, oil, grease, paint residual curing compound, moul d oil or any previous surface treatment that will impair adhesion of the NEOSEAL FLEX CR treatment, or inhibit penetration of the chemicals or water into the surface. These include polymer modified renders and those substrates treated with silicon or silan e water repellents. Remove any laitance and provide an open - pored, slightly rough surface sufficient to act as a mechanical key, essential for adequate adhesion of the NEOSEAL FLEX CR treatment. Areas of weak or honeycombed concrete must be repaired. Hol low, de - bonded renders must be removed and made good. Surfaces to be treated, if not already wet, should be saturated for a period of 24 hours before first application. NEOSEAL FLEX CR system technology requires the presence of water for the active chemica ls to migrate into the concrete. Crystalline development will usually extend to the depth of water penetration. SURFACE PREPARATION: NEOSEAL FLEX CR can be applied immediately after the formwork has been removed, as the water curing process required for NEOSEAL FLEX CR will also ensure full hydration of the concrete. If the treatment is to be exposed and an aesthetically pleasing finish is required, the NEOSEAL FLEX CR should receive a sand/cement render on which to apply the desired finish. Page 2 Always add water to NEOSEAL FLEX CR – not in reverse order. Mix 1 part of water to 2.25 - 2.5 parts NEOSEAL FLEX CR powder by volume. MIXING Leaks and holes drilled to relieve water pressure may be sealed permanently using plugging compound NEOPLUG. To plug leaks under pressure, chase out the area of the leak until water flow is free and insert a length of plastic hose. Seal around the plastic hose with plugging compound as above. Clean the cavity and apply a coat of NEOSEAL FLEX CR and when tacky, fill the cavity with a cementitious mortar containing the plugging compound. When surrounding waterproofing is complete, withdraw the hose and plug t he hole with plugging compound as above, using a gloved thumb to hold it in place until set (approximately 1 minute). Fill the remainder of the hole with NEOPLUG. When the mortar has set, complete the waterproofing, lapping slurry coats of NEOSEAL FLEX C R onto the concrete surrounding the hole. Holes under low pressure can be similarly sealed, but pipe insertion and removal is omitted. PLUGGING LEAKS: The NEOSEAL FLEX CR must be prevented from drying out too rapidly and should be kept damp for 5 - 7 days. Mist spraying with water and covering with polythene is effective when drying out would otherwise take place. Curing compounds are unsuitable for use with NEOSEAL FLEX CR s ystem technology. Protect from weathering, sun, frost and wind for a similar minimum period. Tanks and other water retaining structures may be filled 24 hours after final NEOSEAL FLEX CR application as crystal growth is accelerated by water pressure. N.B .: If a final coating is required over the NEOSEAL FLEX CR , consult your ROYAL WAY INDUSTRIES representative. If the coating is left uncovered, discoloration can occur but this has no effect on the performance of the waterproofing system. If discoloration occurs, grinding can be made to remove the coating. This will not affect the waterproofing properties of the N EOSEAL FLEX CR . CURING Clean tools and equipment immediately after use with water. Use of plastic or rubber containers is recommended. EQUIPEMENT CARE

1. TDS - WP - NF05 - 000_12/20 PROPRETIES C H AR A C TERISTICS The NEOSEAL FLEX CR is a waterproofing coating that ensures the total and permanent solution to water leakage, ingress or seepage in concrete structures or any cementitious substrate. The formation and development of insoluble crystals into water bearing capillaries effective ly blocks the further passage of water and ensures permanent water tightness for the life of the structure. NEOSEAL FLEX CR s upplied as a powder and mixed to a slurry consistency with water. NEOSEAL FLEX CR is applied directly to concrete, block work or cement renders in areas where general waterproofing is required. In powder form, the product may be used as a dry shake on horizontal construction joints.  Compressive Stren gth after 28 days (ASTM C579) > 20 N/mm  Bonding Strength to concrete after 28 days (EN 1542) > 1.0 N/mm2  Chloride Ion Content ≤ 0.03%  Water Pressure: Can resist up to 5 bar of water pressure  Resistanc e to fire (BS 476 - 7): Class 1 PROPERTIES NEOSEAL FLEX CR Surface applied, capillary waterproofing coating for concrete and mortar Page 1 NEOSEAL FLEX CR is effective against both negative and positive water and osmotic pressure and can be applied to the internal or external surface. Wherever possible, however, NEOSEAL FLEX CR should be applied to the surface with which the water is in direct contact. This will result in an accelerated rate of penetration and crystallization into the concrete structure. After the crystallization process has successfully waterproofed the structure, the NEOSEAL FLEX CR active chemicals remain dormant in the concrete. Any later contact with water will reactivate the sealing process.  Water tanks/ towers  Reservoirs  Swimming pools  Water treatment works  Dams  Canals  Harbors  Concrete pipes AREAS OF APPLICATION BS 1881 Part 124: 1988 The vast majority of leaking water - retaining (or excluding) structures constructed of sound dense concrete, leak only at construction or day work joints. Costly remedial work can be avoided by the use of NEOSEAL FLEX CR as a dry shake onto the horizontal s urfaces of joints or as a slurry application on vertical surfaces. In conditions of high water table, NEOSEAL FLEX CR may be applied as a slurry or dry shake over blinding concrete immediately prior to casting the slab. This will prevent ingress of groun d water preventing deterioration and dampness or flooding. Foundations should be treated on the external face wherever possible, as should the face of construction joints. DIRECTIONS FOR USE NEW CONSTRUCTION: STANDARD Moisture and free lime present in the substrate react with the active chemicals in NEOSEAL FLEX CR to create a continuous barrier of insoluble crystals. The crystal formation will penetrate deep into the capillary structure of the concrete, blocking capill aries from the passage of water, whilst permitting the transmission of air and water vapour, enabling the structure to breathe. Rate and penetration of crystalline development varies with the density and surface absorption of the concrete; but the crysta ls will penetrate to the depth to which water is present. Surface penetration sufficient to provide full waterproofing properties can be achieved after 5 - 7 days. METHOD OF APPLICATION
