When mixed, HydroCoat 107 Elastic 2K is thixotropic to enable ease of application by brush or airless spray, providing an even finish with no sagging and excellent adhesion to prepared concrete and masonry substrates, even in vertical and overhead situations.
HydroCoat 107 Elastic 2K is reinforced over static joints and at details and changes of direction with Newton HydroCoat 912-RT Reinforcement Tape.
HydroCoat 107 Elastic 2K hydrates to form a durable, highly alkaline and permanently elastomeric coating which not only protects the concrete or other substrates from water penetration, but also accommodates slight movement in cracks and at correctly specified movement joints.
HydroCoat 107 Elastic 2K is also supported by BDA Agrément® BAB 18-026-P A-UK and is accepted by the NHBC as a suitable waterproofing system for Type A Waterproofing to Grades 1, 2 and 3 - BS 8102:2009 and to covered decks.

Take the usual labour hygiene into account.
PPE should be worn during application. See our Safety & PPE Products.
Consult label and material safety data sheet for more information.
The construction should conform with current Building Regulations, British Standards and relevant Codes of Practice.
New concrete to earth retaining structures should be designed by a Structural Engineer to EN 1992 (Formerly BS 8110). A shuttered finish to vertical surfaces is suitable for Newton HydroCoat 107 Elastic 2K.
Horizontal concrete surfaces should have a surface finish to at least Class of finish U3 and preferably to class U4 or U5 as documented in ‘General Specification for Civil Engineering Works’ section 14: ‘Formwork and Finishes to Concrete’, namely a 'Uniform, dense and smooth surface’. Float marks should be avoided as these will impact on the cost of correct surface preparation.
Newton HydroCoat 107 Elastic 2K can be applied to new concrete providing that:
The concrete is at least 20 N strong
The concrete can be prepared using conventional mechanical preparation methods to remove laitance to floors and release agents to walls
Walls should be designed by a Structural Engineer to withstand the load of the retained earth as well as the expected water pressure as defined by BS 8102:2009.
The mortar joints should be pointed flush to the surface of the wall.
Generally the surfaces to be waterproofed must be structurally stable, clean, dry and free from release agents, dust, laitance, oils, paints or other forms of contamination.
Substrate damage, deterioration, cracks, voids, and holes should be repaired and filled prior to installation of the waterproof membrane with Newton HydroCoat 203-RM Repair Mortar. Deep or structural cracks should be inspected to confirm if they are live or dormant. Suitable repair by qualified personnel is recommended.
Jet washing with minimum pressure of 2500 PSI should be used to remove release agents and surface contamination to concrete walls. Adding mild detergents to the jet wash water will improve effectiveness.
Fine surface cracks and blow-holes should be filled with sand/cement using a bag rubbing technique. Tie-Bolt holes should be filled with Newton HydroCoat 203-RM Repair Mortar.
Joints should be flush pointed. If they are not, re-point or apply a smoothing coat of sand/cement render with Newton HydroCoat 908-LB mixed into the gauging water at 1:2.
Porous block walls should be filled by bag-rubbing with sand/cement.
Existing walls of block or brick will require wall surface preparation such as grit blasting or scabbling to ensure all surface containments are removed and that a good‘key’ is achieved. Remove snots.
In all cases, concrete floors should be ground or sand blasted to remove laitance. Vacuum clean after. Large holes or indentations should be filled Newton HydroCoat 203-RM Repair Mortar.
Clean to remove surface contaminants and abrade to a slightly textured finish.
Reinforce static joints with Newton HydroCoat 912-RTReinforcement Tape. Over shrinkage joints, use 25mm wide masking tape to create delamination.
With movement joints, lap the HydroCoat 107 into the joint and then use the standard Newton 106 FlexProof movement joint detail.
Walls and Soffits: Prior to slurry tanking, porous substrates should be sealed with sand / cement using a bag rubbing technique.
Internal Slabs and Rafts: Porous substrates should be sealed with Newton HydroCoat 903 Primer.
External Decks: Should be primed with Newton HydroCoat 903 Primer.
Newton HydroCoat 107 Elastic 2K should be mixed with a high quality mixer & stirrer, such as a Collomix DLX Stirrer or Collomix KR Stirrer matched to a Collomix XO1 Hand Mixer or XO4 Hand Mixer.
Shake Part A (Bottle) thoroughly and pour into clean mixing vessel.
Add Part B (Powder) slowly whilst mixing slowly.
Mix for 5 minutes until smooth, entrapping as little air as possible.
Continuously scrape sides to prevent lumps forming and to ensure all of Part A is mixed with all of Part B.
Mix for a minimum of 5 minutes and use without delay.
✔ Squeegee ✔ Roller ✔ Pin Leveller ✔ Brush ✔ Trowel
The mixed slurry can be applied by Brush, Squeegee, Roller, Trowel or Pin Leveller.
Ensure that air is not entrapped into the surface of horizontal applications by using a spiked roller as soon as the product is placed.
With two coat applications, the second coat can be applied when the first coat is still ‘green’ and slightly tacky and up to five days after the first coat has been applied.
After five days, the first coat will need to be washed to remove dust. In addition, a primer of Newton HydroCoat 908-LB mixed 1:1 with water can be applied toenhance adhesion of the second coat to the first.
Approx 3.2 kg/m² per coat. Membrane Thickness - 2.0mm
Newton HydroCoat 107 Elastic 2Kis a two-part product and a chemical curing reaction starts as soon as the two parts are mixed.
Pot life is 45 minutes at 20ºC. Product must be used before it starts to go off / over thicken.
Newton HydroCoat 107 Elastic 2K is a cement-based product and so requires curing. Accelerated drying must be avoided.
If the conditions are hot, sunny and/or very windy the finished membrane must be protected from accelerated drying with the application of Newton HydroCoat 905-CM, a simple to apply liquid curing membrane.
In floor and deck applications, coloured sands or grit can be cast liberally onto the surface to provide effective curing, whilst also creating an abrasion and slip-resistant finish.
Curing must commence within 10-15 minutes of the completed application of the coating.
When specified, installed and protected in accordance with the Data Sheet, fully and permanently isolated from UV light and physical damage or wearing, and only to those substrates confirmed within, Newton HydroCoat 107 Elastic 2K has a service life that can be equal to the design life of the structure.
Newton 107F is guaranteed to resist weathering for up to 10 Years. The membrane is not UV colour stable and will slightly fade in colour over time, and it may take a few months for the colour to be consistent. Over time discolouration due to weathering may take place, but the membrane will be serviceable.
The membrane is not hard wearing and should be protected against wear.
Do not apply prior to rain - Please refer to information within the Curing Table on Page 2 of the Technical Data Sheet
Do not apply at temperatures lower than +5°C or higher than +30°C
Always use the correct preparation and priming of the support substrate as directed above
