Wall Finishespages 245-257 in "Interior Construction and Detailing"

Wall finishes include:

those applied as a single, thin decorative covering, such as paint,

wallpaper, and vinyl wallcovering,

and those composed of several construction elements that can addsubstantial thickness to a wall, such as ceramic tile or stone panels.

Brendan Clarke of Maharam, presented a good variety of wall

coverings, including fabrics, vinyls, and some metallic based sheet

products.

Acoustical panels

when a high degree of sound absorption is desired, acoustical

panels can be a good choice.

Two primary decisions regarding acoustical panels:

fabric type

core material


4/68

fabric for acoustical panels must be permeable, to allow for sound

energy to pass through.

this also means that the fabric should not have a backing.

fabrics for acoustical panels should be 'hydrophobic' which means

that they do not hold and absorb moisture.


5/68

Acoustical panels: expanded polypropylene:moisture resistant, impact resistant, tackable, lightweight, indoor-outdoor


6/68

High impact fabric covered panels:compressed figerglass core, class A fire rated, chemically hardened edges

8/68

For acoustical panel covering, it is important to use fabric that

does not absorb and retain moisture.

Hydrophobic fabrics do not absorb and retain moisture.

These include polyester, acetates, nylon.

Hydrophillic fabrics absorb and retain moisture.

These include cotton, wool, and silk.

Stone used as a wall finish

typical stone used for wall finishes include:

granite, marble, limestone, slate, sandstone.

manmade products, such as cast stone, can mimic the visual andmaterial qualities of natural stone.


10/68

Stone tiles and panels

stone tiles, and panels, used as wall finish materials have definite

size constraints.

the term tile means a small, (generally no larger than 12x12) thin,

modular piece of material. tiles can be made of metal, glass, wood,leather, plastic, ceramics, cork, and nearly any other material.

tile does not always mean ceramic.

the table on page 252 of "Interior Construction and Detailing" lists avariety of stone types and size limitations or requirements.


11/68

details in stone wall finish installation

stone used as a finished wall surface can be achieved using two

different approaches:

tiles: thin, small, modular, pieces, typically no larger than 12" x 12".

panels/slabs: 3/4" up to 4" thick.


12/68

Stone tiles:granite, quartzite, multi colored slate, black slate, green slate, multi-colored

ceramic tile


34/68

ceramic tile

Ceramic tile is especially useful in kitchens and bathrooms because

it is water-resistant and easy to clean and extremely durable.

Made from a mixture of clays and fired at high temperatures, tile is

used for wall coverings, floors, showers, countertops, bathsurrounds, and more.

Tiles used on walls and counters are generally glazed


35/68

Grout, a kind of mortar, is spread between

tiles to lock them in place and fill the joints

between them. Grout may be white or

colored with pigment.


36/68

Ceramic tile may be applied directly over

drywallif the room is likely to be damp,

special moisture-resistant drywall should

be used. Or tile may be applied to a mortarbed or a backer board made of a ceramic

aggregate core that is coated with a thin

fiberglass mesh.

Paints and Coatings

What is paint?

Paints are made up of four components:

pigment, binder, solvent/liquid carrier, and

additives.

Varnishes, which form transparent or semi-

transparent films, are made up of the last three

components, with colored varnishes containing

small amounts of pigment.


46/68

Paint is manufactured to meet specific needs


47/68

Types of Paint

water base paint

solvent base paint

these are the two basic types of paint generally available.

paint may have physical or chemical characteristics such as:

matte surface, semi gloss surface, high gloss surface

non-drip paint, primer, undercoats, anti-condensation,

fire retardant paint (intumescent), metallic, concrete floorpaint, porch paint, anti-fungus paint, heat resistant paint


48/68

Pigments, which give color and

opacity/covering power, are finely

dispersed solid particles. In some cases

they can be used to impart certainprotective properties, eg rust prevention,

and to control gloss levels


49/68

The binder is the material that forms the

film, giving protection to the substrate and

keeping the pigment in place and evenly

dispersed. It may be made up of a single,or a combination of polymers. The binder

may be dissolved in a solvent, or in the

form of an emulsion or colloidal dispersionin water. This results in solvent-borne and

water-borne paints, respectively.


50/68

The solvent/liquid carrier is used to effect

application of the coating. It may be water or an

organic solvent, or a mixture of both, and thins

the paint or varnish, allowing it to be brushed,sprayed, dipped or rolled.

Once on the substrate, the solvent evaporates,

leaving the dry film coating. The term 'liquid

carrier' is preferable because the liquid may notbe a true solvent for the binder.


51/68

Additives are used, in small amounts, to

modify the film or paint. Examples are

driers, which promote the drying time of

some coatings; flow-control agents, whichgive a smooth surface; defoamers, which

prevent the formation of bubbles that could

dry in the film; and anti-skinning agents toprevent the paint from forming a 'skin' in

the can


52/68

Water Base Vs. Solvent Base

Water-based: non-flammable, clean up

with water, quick drying in good

conditions, low VOC content, low odor,

non-yellowing

Solvent-based: better drying in cold,

damp conditions, better low-temperaturestorage, no can corrosion problems, less

wood-grain raising, higher gloss


53/68


54/68

Fire retardant and fire resistant coatings

flame retardant paints slow the rate of flame spread

intumescent coatings bubble up, or expand, when exposed

to extremely high heat

fire resistant paints are not as effective at controlling the

spread of flames as intumescent, or fire retardant paints.

fire resistant paint does not burn, but it also does not helpcontrol the spread of the flames

Wallcoverings

Wallcoverings offer improved durability over

typical paint finishes while providing texture and

pattern to the wall surface.

The most widely used wallcoverings forcommercial use are vinyls.

There is a classification system used to compare

all types of commercial wallcovering.

This is the ASTM F793 Standard Classification

of Wallcoverings by Durability Characteristics.


59/68

Wallcovering Classification

Category 1: decorative only

Category 2: decorative with medium

serviceability

Category 3: decorative with high serviceability Category 4: Type I Commercial serviceability

Category 5: Type II Commercial serviceability

Category 6: Type III Commercial serviceability


60/68

Vinyl Wallcoverings

There is a special standard that describes

vinyl wallcovering as:

Type I: light duty, with a minimum weight of 7

oz/sq. yard

Type II: medium duty, with a minimum weight of

13 oz/sq. yard Type III: heavy duty, with a minimum weight of

22 oz/sq. yard


61/68

Materials & Backings

Vinyl: scrim, a loosely woven fabric backing used on Type I

vinyls

Osnaburg, a loose open weave fabric used on Type IIvinyls

Drill, a dense woven fabric with good dimensional

stability used on Type II and Type III vinyls

Nonwoven, a paperlike backing used on Type I vinyls.


62/68

Surface Materials for Walls

Wood Veneer: bonding wood veneer (about 1/64"thick) to a woven backing material.

Textiles: paper backing or a latex coating

Fiberglass: a fiberglass fabric that is applied to abacking. Fiberglass wallcoverings must be painted after

they are installed.

Wallpaper: paper wallcoverings are generallyrestricted to residential use because of fragility and poor

wear resistance.

Upholstered Wall Systems

site constructed coverings that stretch

fabric taut over a frame and infill material.

the frame material is typically either a

plastic extrusion, or a wood frame.

Ceiling Finishes

Ceilings are central in defining the volume

of a space and shape the diffusion of

sound and light within a space.

Ceilings also typically conceal an array ofsystems components, in a plenum space.

Ceilings in a space can be:

suspended

exposed

tightly attached
