AFTERCARE & MAINTENANCE
General Maintenance
& Cleaning of WBS Silicone & Acrylic Renders
|
Small
Dust Marks
Mild soapy water may remove small areas of cement dust
etc however it must be stressed that this action may
also worsen the problem due to possible staining on
dark colours. |
|
Minor
Damaged Areas
If there are only a few splashes/marks then very carefully
mechanically remove (with knife or similar sharp instrument)
the splashes, care should be taken not to damage the
render. Make good with silicone or acrylic paint to
match. |
|
Large
Damaged Areas
If there are larger areas affected and the splashes
can be removed without damaging the render (and/or change
texture) then paint the entire area with a silicone
or acrylic paint to match. |
|
Severely
Damaged Areas
If the splashes cannot be removed without damaging the
render/texture then the whole area will need to be re-coated
by using a base coat with mesh followed by the primer
and silicone finish.
N.B. When using very dark colours it may not be possible
to supply silicone paint due to the pigments used, therefore
it may be necessary to paint the affected area with
an acrylic paint finish.
Please consult with WBS Technical staff for further
details. |

Addition
of Metalwork
Any metalwork to be added to the building such as clothes
lines, hooks, etc, should be well painted or otherwise
protected if they are made from a ferrous metal. Attachment
to the building should be made with fixings, which penetrate
through the system and into the substrate, for example,
sleeved bolts or extended length fixings. These should
be sealed at their abutment with the system using a
good quality acrylic sealant. |
|
Waste
Pipes
Any additional waste pipes, etc, which penetrate the
system should be passed through holes cut a maximum
of ¼“ (6mm approx.) larger than the pipe
diameter, which can then be sealed between pipe and
system, using good quality acrylic sealant. |
|
Property
Extensions
Any additions to the property, for example, outhouses,
lean-to’s, should be sealed where it abuts the
addition using a good quality acrylic sealant. |
|
Graffiti
Removal
If graffiti vandalism is a problem, then specialist
anti-graffiti treatments are available, details of which
may be obtained from WBS. |
|
Garden
& Plant Considerations
Keep garden soil levels as far below the system level
as possible as soil splashing will soon discolour the
base of the system.
Plants, trees and creepers can cause staining of lightly
coloured finishes and care should therefore be taken
in the positioning of them.
Climbing plants, provided they have a properly fixed
trellis available for them will not cause any damage
to the system. However, they may cause some staining
of lightly coloured finishes. |

Satellite
Dish Installation
If fitting a satellite dish or receiver to completed
areas of External Wall Insulation, either of the 2 methods
outlined here should be adopted:
i) Drill out appropriately sized holes through the system
back to the wall surface and insert cylindrical non-corrosive
tension spacers at the relevant dish fixing points.
The support bracket for the dish may then be installed
as normal but should be tightened against the spacers
and not the system. Silicone sealant must be neatly
applied around the spacers to ensure water penetration
is prohibited.
ii) Obtained suitably sized treated timber blocks that
are at least 15mm thicker than the overall system thickness
and will safely accommodate the dish bracket.
Use these blocks as a stencil and neatly cut out the
system at appropriate fixing points back to the original
surface. Insert the blocks and secure to the structure
with non-corrosive mechanical fixings. Apply silicone
sealant between the blocks and the surrounding system
finish to prevent water ingress.
The dish’s brackets may then be screw fixed to
the timber blocks. |
