20L Seal It One Liquid Membrane Coat Roofing Waterproof Hybrid Roof Barrier Grey

Description:
SEAL IT LIQUID MEMBRANE System comprises a highly reflective liquid applied hybrid coating formulated to a
solvent‐free, non‐flammable formulation for professional roofing applications. Used in conjunction with a primer,
accelerator and reinforcing mat, where required, the system gives the ultimate alternative to
bitumen based and GRP waterproofing roof membranes for all existing roof substrates.

Benefits:
l No specialist training required.
l Breathable.
l Adheres to all common building substrates.
l Solvent‐free and non‐flammable.
l Helps reduce energy costs.
l All weather application.
l Permanently flexible.
l Rain safe in 15 minutes.
l Withstands chemical attack.
l Simple application.
l Made in the UK.
l Can be used below 5o
C if used in conjunction with SEAL IT
ACCELERATOR.
Based on hybrid technology, SEAL IT LIQUID MEMBRANE has high
elasticity, even under climatic weather variations. It does not
harden under cold conditions and has very high stability to
temperature variations (from -500
C to +1200
C), to UV radiation and
to external chemical attack. Excellent resistance to ageing, ultraviolet and discolouration. It also provides water vapour
permeability, allowing the surface to breath. Under test
conditions, SEAL IT LIQUID MEMBRANE has superb thermal
properties and outperforms black bitumen by 36% at just 0.8mm
thickness, it is also 11.3% more efficient than solar reflective paint
which helps reduce energy costs.

Uses
Offering primerless adhesion on a wide variety of building and
roofing surfaces, such as metal, treated and untreated wood,
brick, stone, polyester, glass, lead, bitumen coating*, roof tiles,
plastics, polycarbonate, concrete, without heating or bonding.
Ideal for repairing flat roofs, pitch roofs (less than 10o
), leaking
flashing, guttering and roof lights and cracked roofing panels,
chimney stacks, corrugated or plate roofing materials, zinc, steel,
fibre-cement and façade panels creating an impermeable seal to
repel water damage and provide resistance to degradation from
natural weathering like rain, snow and sunlight. Also suitable for
zinc guttering, down pipes, ventilation ducts, etc.

Preparation
Protect any surfaces not requiring application to
avoid accidental damage or contamination, this is
especially important when applying the product by
spray. Protect any areas not to be treated with
masking tape or protection film, making sure it is
fully bonded so as not to cause any trip hazards. All surfaces
should be degreased, either with hot water or with a pad soaked
in solvent, followed by wiping with a clean cloth. All loose
materials must be removed by brushing, scraping or high pressure
water. New concrete and mortars must be at least 28 days old.
Any organic growth should be treated with Bond It MOULD STOP
fungicidal wash or equivalent.
Irregular masonry surfaces should be filled and levelled before
applying SEAL IT LIQUID MEMBRANE. Cracks greater than 2mm wide
should be filled prior to application. This can be done with SEAL IT
CRACKS & EDING SEALER or for larger gaps use the SEAL IT
REINFORCING MAT. *On bitumen/asphalt or roofing felt surfaces
SEAL IT LIQUID MEMBRANE must be used in conjunction with SEAL IT
PRIMER (refer to relevant datasheet for full instructions). Note: the
primer can only be applied when the outside temperature is
above 5oC.
This product can be applied to damp surfaces. If there is standing
water, brush this away and then apply SEAL IT LIQUID MEMBRANE to
the damp surface. Do not worry if it then rains and water pools on
top of the coating, it will not be affected and will continue to cure.
Once cured the membrane is resistant to temporary water
ponding, however, adequate drainage in the roof design is
required to ensure that no permanent ponding can occur.

Application
Remove all surplus packaging from inside the tin, including
dessicant and protective films. We would advise stirring the
coating thoroughly before use. Once container is opened and
product is exposed to the air it will start to cure so apply
immediately. It is also recommended that the full tub is used on
the installation otherwise there is the risk it could potentially skin
over and go lumpy if left in the tin for a period of time once it has
been exposed to air.

Do not dilute. Apply product to the surface with a brush (longer
bristle brushes are recommended on rough substrates), short pile
roller, trowel, spatula, squeegee or industrial spray equipment.
The coating should be evenly applied at a rate of approximately
1m² per 1L at 1mm thickness according to the porosity and
roughness of the surface to be treated, up to a minimum of 1mm
thickness. Some surfaces may require two coats. The second coat
should be applied after 8-24 hours, when the first coat is
sufficiently dry to walk on. It is recommended the coating is
extended beyond the substrate to create a self-terminating
flashing or use SEAL IT CRACKS & EDGING SEALER to seal edges. Take
care when conditions are windy and using spray method in
particular, avoid contact with substrates not requiring coating.
Product can be removed before it cures by acetone, Bond It WHITE
SPIRIT or Bond It MULTI-WIPES if unwanted contact is made to
surfaces.
We recommend a small discreet area approximately 1m2 is treated
with the SEAL IT LIQUID MEMBRANE prior to applying to the full
surface area for the purpose of identifying any adverse reaction
between product and the substrate.

Drying Times
Tack free after approximately 2 hours after application (@23oC
and a relative humidity of 50%). It is capable of resisting heavy
rain 3 hours after application. After application the surface should
be subjected to as little traffic as possible. Area should not be fully
trafficked for at least 72 hours to preserve integrity of coating.
Damage to the roof by other trades will not be the responsibility
of Bond It.

Colour
White to special request but
will be subject to a minimum order quantity. Please request
details.

Storage Conditions
Shelf life is 12 months from its date of manufacture when stored
at a temperature between +5oC and +30oC in its original unopened
packaging. Once opened this product will begin to cure and is
recommended that the full tub is used to avoid it skinning over.

Disposal of Containers
Do not leave empty containers where residue could be harmful to
children, animals or the environment. Replace lids and remove
any containers and waste material from site to a central disposal
point in accordance with local regulations.

Health & Safety
Please refer to separate material safety data sheet for full
handling, use and storage instructions. Keep out of reach of
children. It is the users responsibility to determine suitability for
use. If in doubt contact our Technical Department for advice.

Material Warranty
25 year material warranty, warrants the purchaser that SEAL IT
LIQUID MEMBRANE will be free from proven product defects for a
period of 25 years from date of application. This is provided the
material has been laid to the correct specification and all
application instructions have been followed and adhered to. For
further information please speak to the Bond It Technical team.

Coverage
Approximately 1 Litre of SEAL IT LIQUID MEMBRANE will cover
approximately 1m2 at 1mm thickness.

Cleaning Of Tools
Clean tools using Acetone, MEK or Bond It WHITE SPIRIT. Trowels
and squeegees can be easily wiped clean with the aid of Bond It
MULTI-WIPES. Cured material can only be removed mechanically
with a spatula or similar tool.

Limitations
Not recommended for use when temperatures of less than 5oC are
expected in the next 24 hours (unless using in conjunction with
the SEAL IT ACCELERATOR, please refer to relevant instructions). Not
suitable for use on low surface energy plastics such as PE, PP and
PTFE. Adhesion to EPDM sheets needs to be checked on a small
test area before proceeding. Do not use on surfaces that bleed oils
or plasticisers. Blistering can occur when MEMBRANE is applied
onto damp substrates that are not able to dry out from
underneath. If the minimum thickness is not achieved, cracks and
structural failure in the coating may occur. Only walk on roof
surfaces restored with SEAL IT LIQUID MEMBRANE for maintenance
purposes.
This is not a wearing surface and is not anti-slip and as such
should not be used as a pedestrian walkway, deck or frequently
trafficked area. Small chip aggregate can be added to the coating
to provide limited slip resistance if the area will be subject to light
and occasional foot traffic. It is also not recommended for areas
where there is low atmospheric moisture present as product will
not cure. It is essential that bitumens, roof felts, etc. are properly
and completely primed before SEAL IT LIQUID MEMBRANE
application or product failure WILL occur. Please note application
temperature limits for this system.
