| |
| Q. How
long will it take to sand a medium-sized room? |
A medium sized
room takes approx 4 to 5 hours if it is old floorboards
which have not been sanded before. On previously finished
and hardwood or parquet floors, it should take a little
less.

| |
| Q.
Can
I use a big belt machine on parquet? |
Yes, because
our big belt machine is lever-operated so you can control
the raising and lowering of the drum. It won’t
damage the floor. |
| |
For best results, use a fine-finisher
to “table-top” finish afterwords.

| |
| Q.
Do
I need to punch the nails in below the surface of the
floor? |
Traditionally, because of poor-quality
paper-backed abrasives, this was necessary. However, with
our cloth abrasives, provided the nails are level with
the floor and not above them, you don’t need to
set the nails.

| |
| Q.
Why
is the cloth 24 grit abrasive expensive? |
We do 3 qualities
of the rough ‘clean-up’, or 24 grit grade
for the regular big belt machine. Although we stock it, we
don’t recommend the regular hire shop type paper,
as the abrasive is too soft for such a large, heavy-duty
grit, as this quality frequently breaks and blocks the
machine. Overall it is also more expensive! You use
3 or 4 sheets to every 1 of our silicone carbide cloth
belts. Our cloth belts are nylon-impregnated and also
have a superior glue holding the abrasive grit so they
last much longer.
The most efficient and fastest cutting of the lot is
our top-of-the range Zirconia sheet which lasts the
longest, easily 5 or 6 times longer than a normal hire
shop paper and cuts the fastest. The cloth is thicker
and the grit continually renews itself by splitting
and forming new sharp particles.

| |
| Q.
Can
the sanders get rid of paint, glue and carpet foam? |
Regular household
paint on a floor is not usually an issue, because of
our unique abrasives. Zirconia cloth belts should definitely
be used to remove regular household paint from a floor.
The black bitumen-type paint which frequently ‘picture-frames’
floors in old houses, usually about a metre all round
the edge, can be more of a challenge.
However, with the zirconia abrasive, and the instructions
in our book on how to get rid of it, you should get
it all off. It will take a little longer, however, you
will be rewarded with a particularly attractive floor
at the end, because usually the quality of wood was
superior when this finish was put around the edges.
(The first few coats of that the “bitumen”
would have been put on as a tint for the wood grain
to show through. Traditionally, the tint matched the
tiles in the fireplace, but over many applications the
original colour would have been lost.)

| Q.
How
much will the abrasive cost for the big belt machine and edger? |
Approx £18-25 per medium-sized
room.

| Q.
How
do I get the bit right in the corners and behind radiators
clean? |
We sell a very useful item called
a Tungsten scraper for that.

| |
| Q.
Do
you provide goggles, gloves, masks and earmuffs? |
In short, "Yes"!
back to top |
| |
| Q.
Should
I decorate before or after sanding? |
Before is usually
best. It is much easier to touch up the odd scuff on
the skirting caused by the edger (although ours have
a protective Velcro strip on the front) than try to
protect your newly-varnished floor or re-do new lacquer
where it has been scratched by ladders or splashed with
paint.
Remember our machines are virtually dust-free, so any
small amount of dust can easily be got rid of.

| |
| Q.
What
kind of varnish should I use? |
We usually
recommend, and only stock, high-quality water-based
varnish products, as they are non-toxic, non-yellowing
and quick drying. Please note that this new, water-based
technology has only really matured in the last few years,
and some well-known and widely-sold products are not
very durable. They can need re-doing in under a year
in some cases, whereas our varnishes are designed to
last at least 5 years, some up to 20, subject to conditions
and regular maintenance, etc.

| Q.
How
many coats will I need? |
2 coats in
lightly-used areas like bedrooms, 3 coats in living
areas, and 4 coats in entrance halls, kitchens and bathrooms.

| |
| Q.
How
much water-based varnish will I need? |
Approximately 5L for 2 coats on
25 square metres.

| |
| Q.
I
can't decide whether to use gloss, satin or matt. |
Gloss as a
finish is not popular as it shows up any minor imperfections
in the floor. However, it is sometimes used effectively
on tropical/darker woods for a particular look. Satin,
which is between gloss and matt, is the popular contemporary
look. It has a sheen and reflects some light, and is
forgiving of the odd minor imperfection. Matt, although
still a small part of the market, gives a very natural
waxed look.

| |
| Q.
Which
wears better, gloss, satin or matt? |
In the 20th
century, when solvent-based polyurethanes were common,
gloss was harder wearing, because manufacturers used
additives which weaken the finish to achieve a satin
or matt look. However, with our range of water-based
varnishes, there is no difference in durability between
matt, satin and gloss finishes.

| |
| Q.
What's
the best way to apply the varnish? |
Professionals
use rollers. However, if you are doing one or two rooms,
you can achieve better results with a large inexpensive
floor brush, which we stock. If doing a hardwood floor
in a large area, it would be worth using a roller or
T-bar.

| |
| Q.
How
long does it take to dry? |
Around 1 hour
for the first coat, 2 hours for the second coat. On
a damp humid day, a little longer.

| |
| Q.
What's
the difference between varnishes, oils and waxes? |
Varnish coats
the top surface of the floor, and forms a hard surface
when it dries. This is the usual way of finishing wood
floors. |
| |
Oil is sometimes
used on hardwoods i.e. oak, walnut, tropical hardwoods
etc. It works by being absorbed into the timber and
relies on the natural inherent strength of the timber
itself to protect its surface. If oil is being used,
the floor should be fine-finished in preparation. With
pine floorboards and the softer hardwoods, oil finish
doesn’t seem to work as well. It is important
that you see an oiled finish with your type of wood
floor to see if this finish suits your floor style. |

Shellack and
wax finish: pre-1960’s, shellack, a French-polish
type varnish was used, which was then waxed over. This
system is very highmaintenance and not suitable at all
in kitchens and living rooms, as wax leaves white deposits
when in contact with water. It is also very slippery
when wet.
