Choosing the right product will depend on the type of roof you have and also the
intended application.
Heat fused torch on membranes
> Heat fused systems, also called torch on membranes,are generally used to
waterproof large flat roofs.Torch on is a specialized waterproofing product that
should only be applied by experienced applicators.
Cold applied systems
These types of products can specialized or available to the Mr. DIY roof repairer.
Here are some examples of products commonly found.
1.Acrylic
waterproofing systems
The benefit
of this type of product is that it is relatively cheap and easy
to use.On the other hand,because it is so simple in concept, most
D.I.Y enthusiasts and well meaning contractors don't follow the
instructions properly and therefore fail when trying to use this
type of product.
Another thing to consider
is that this can be very messy so its best not to test out your
new waterproofing skills on a piece of roof that's visible to the
public.You also
need to ensure that the surfaces you intend to applying too are
properly cleaned and prepared before application takes place.
2.Peel
and paste membranes
These systems come on
a roll much like double sided tape.Generally the rolls are about
300mm wide by 10m in length. These systems are cheap and readily
available but are difficult to mold onto. (even onto slightly rough
surfaces)You would first need to create a smooth surface onto which
you could more easily apply, and then you would still need to spend
tedious amounts of time working angles and corners.(Don't count
on getting this right first time)
3.Mastics
Mastic are sticky,
thick compounds that are good for plugging small holes.They are
your typical silicones, polyurethanes and other rubber goodies.
Try to use similar
products with each other. for example don't try to use a silicone
based mastic on a bitumen based waterproofing system....They won't
bond for very long.
5.
Liquid Based
Liquid waterproofing
systems range from the relatively cheap to the insanely expensive.
They are usually poured on or applied by means of a block brush.
Specialist applicators may use other means of applying this to larger
areas but the DIY applicator should stick to smaller areas. As with
all products 70% of the work lies in preparation. A well prepared,
clean substrate will result in a good bond.
