INTRODUCTION Hardboard (not to be confused with hardwood), also called high-density

fiberboard (HDF), is a type of fiberboard, which is an engineered wood

product. This product is also known under Isorel or asonite brand

na!es.

It is si!ilar to particle board and !ediu!-density fiberboard, but is

denser and !uch stronger and harder because it is !ade out of

e"ploded wood fibers that ha#e been highly co!pressed.

$onse%uently, the density of hardboard is &' lbs. or !ore per cubic foot

( kg*!+) and is usually about - lbs. per cubic foot ('/kg*!+).

It differs fro! particle board in that the bonding of the wood fibers

re%uires no additional !aterials, although resin is often added.

The hardboard #ariety is !ade without resin. The HDF #ersion is !ade

with resin. 0nlike particle board, it will not split or crack. HDF is a !uch stronger board co!pared to DF and it gi#es a

s!ooth and unifor! surface where#er it is applied. HDF does

not ha#e any grain and it can be finished by applying paint on it.

If you want wood grain finishing then you would need to put a

#eneer or teak ply on the HDF board

MANUFACTURE

The process of manufacturing fiberboard combines natural wood

fibers with synthetic polymer resins for bonding purposes. These

materials are mixed and then molded together in a dry environment

using high temperature and pressure to bond and shape the mixture

into individual panels. This method of manufacture in a dry process

helps to bond the elements together in a more uniform density that

retains its composite structure

USES

0nlike solid wood, hardboard has no grain.

1 wood #eneer can be glued onto it to gi#e the appearance of

solid wood.

7ther o#erlays include For!ica, la!inated papers, cera!ics, and

#inyl.

It has !any uses, such as a substrate. It is used in construction,

flooring, furniture, ho!e appliances, auto!obiles and cabinetry,

and is popular a!ong acrylic and oil painters as a painting

surface due to its econo!ical price (though it !ust be coated

with gesso or can#as before use).

Hardboard has often been used as the surface !aterial in

clipboards, especially older !odels. It is also used as the final layer in !any skateboard ra!ps and

the half-pipe.

MAINTENANCE

To protect "! the steps below should be ta#en.

$a#e sure that the board does not get in touch with water as it can

damage it.

%lean the board with a clean soft cloth to remove the dust.

o not mop with damp cloth.

&nce you finish the "! with paint or veneer wood then the

maintenance steps for those finishes should be followed accordingly.

HDF is High density board has !ore strength co!pared to DF

and 5article board

>reat solution for indoor and outdoor furniture, wall panelling,

furniture, roo! partitions, and doors.

Disad#antages

HDF is e"pensi#e when co!pared with particle board and DF. 4till a lot of carpenters prefer wood block board co!pared to

HDF as they are !ore confident about the nail holding

capabilities of natural wood whose blocks are used to build the

block board
