CHRISTMAS CLOSURE 24/25: We’re closing from 1pm on the 20th December 2024, until 6th January 2025. Read our blog for full details!
Newton 603 is a High Quality, 3mm Stud Flooring Damp Proofing Membrane suitable for use above new and existing floors. The 3mm studs allow for pressure equalisation of dampness within the floor below, allowing for dissipation at the room perimeter and subsequent drying of the floor.
Supplied in (W) 2.0M x (L) 20M - (40M²) Rolls.

Newton 603 is a high quality flooring damp proofing membrane suitable for use above new and existing floors. The 3mm studs allow for pressure equalisation of dampness within the floor below, allowing for dissipation at the room perimeter and subsequent drying of the floor.
The studs also give slight compression to footfall, making the floor very responsive, comfortable and ideal as the floor membrane for performance sports floors.
Newton 603 Damp Proofing Membrane uncouples the floor finish from the substrate so that movement is not transferred to the floor finish above.
This Newton Membrane also bridges small cracks, allowing for quick floor installation above less than ideal substrate.
This Newton Membrane is guaranteed against deterioration for 30 years, and has a life expectancy of at least 50 years (DIN 9001:2000) and is inert with high compressive loading stability. It is highly resistant to water, alkalies, saline solutions and organic acids, and it is not affected by minerals. It is also resistant to bacteria, fungi and other small organisms.
Newton damp proofing Membranes can be finished over with screed, 18mm or 22mm T&G chipboard or partical board. Laminate and timber flooring should be installed over a layer of 18mm or 22mm T&G chipboard

Can be used as the flooring membrane within a Basement Waterproofing specification if specified by a trained waterproofing surveyor
Starting at one side of the room, unroll the membrane with the studs down and cut to fit the room as one would a carpet.
Newton 603 does not have a flange, so a butted joint is used.
Starting at one side of the room, unroll the membrane with the studs down. The next membrane width is rolled out so that edges of the two rolls meet at a ‘butt joint’. Clean both edges.
Newton Overtape (150mm wide) is then applied above the butted joint to join the two widths of membrane. Newton Overtape has a split backing paper, and it is easier to apply the Overtape to one roll and then the other by removing half the backing paper at a time. This process is repeated until all areas are covered.
Apply more pressure with the palm of your hand to further seal the whole of the joint. A Hot Air Gun should be used to help sealing, especially in cold or damp conditions.
Where the floor membrane is required to be jointed to horizontal DPC’s, such as DPC Roll, through internal and external walls, these joints should be sealed with Newton Waterseal Tape. Ensure both surfaces are clean and dry before attempting to make these joints.
If there are any services through the floor, the membrane can be cut and trimmed around them, and the gap filled and sealed using a high quality MS or SMX Polymer Adhesive. If necessary, a patch of membrane or Damp Proof Course (DPC) is laid over and sealed to the service with Waterseal Rope, and around its perimeter with Waterseal Tape. It should be noted that protrusions through the floor slab / raft should be avoided wherever possible as they create weaknesses that allow unnecessary water ingress.
The specified floor finish can now be laid directly over the floor membrane, which must not be punctured by any fixings through the floor. When a timber floor finish is preferred you must allow an expansion gap around the wall edge.
Speak to the supplier of the floor finish to confirm the correct size of this expansion gap.
