Quarry tile: glazed or unglazed, typically 6 insq facial area, and made by the extrusion process from natural clay
Porcelain: similar to ceramic but uses lighter and denser clay, and fired at a high temperature. The firing process removes almost all water from tile, making for a tile more dense and harder that ceramic

26
Q

What are nonvitreous tiles

Nonvitreous tile: has a water absorption rate more than 7%

27
Q

impervious tile has

A

28
Q

semivitreous tile has

A

has water absorption between 0.5% and 7%

29
Q

hat are the 2 most common methods of laying a tile floor?

A

Thin-set: tiles laid on a suitable substrate with a thin coating of dry-set or latex-portland cement mortar and grouted
Full mortar bed: tile and reinforced mortar are separated from the structural floor with a cleavage membrane to allow the two floors to move independently

30
Q

When should tiles be installed with a thin-set method or full mortar bed method?

A

Thin-set methods must be used only on level sub-floor that won’t deflect or move in anyway. If these conditions can not be met, full mortar method should be used.

31
Q

When are expansion joints required in ceramic tile floors?

A

For large expanses of tile and where tile abuts restraining surfaces, like at colcums

32
Q

ASTM D2047

Q

ASTM C1028

A

SCF of ceramic tile (Both dry and wet)

34
Q

ASTM F609

A

TEST using a horizontal pull simmeter COF of footweat

35
Q

A

SAFTEY SPEC OF SLIP RESISTANCE BATHING FACILITIES (SOAPY WATER)

36
Q

What is laminate flooring/what is it composed of?

A

Composed of a clear wearing sheet over melamine -impregnated decorative printed sheet with core layers of phenolic- impregnated kraft paper, these sheets are laminate to a high density fibreboard core under heat and pressure and covered with a water resistant backing sheet.

37
Q

What are advantages and disadvantages of laminate flooring?

A

Advantages: decorative print / endless possibilities, durable, stain resistant, easy to install, low cost

Disadvantages; not natural / environmental factors, not suitable for wet areas

38
Q

What is seamless flooring?

A

Mixture of resin matrix, fillers, decorative materials applied in a liquid form that cures into a hard seamless floor.

39
Q

What is “coefficent of friction” (COF)

A

Measurement of the degree of slip resistance on a floor surface between 0-1. The higher the COF , the less slippery the surface

40
Q

What protocol is used to measure COF on a flooring material ?

A

DCOF AcuTest - which is contained in ANSI A137

41
Q

What are the 4 components of paint?

Additives: components added to the paint to impart certain attributes

42
Q

Venetian blinds: horizontal slats whose angle can be adjusted with a control cord and varying levels with another cord

Mini blinds: same as Venetian except slats are mini and angle controlled with rod

Vertical blinds: slats on a vertical top track and can pull to the side to reveal window

48
Q

49
Q

What are the 4 types of drapery pleats?

A

Pinch pleat, stack pleat, roll pleat, accordion pleat

50
Q

How is the amout of carpet needed calculated?

A

tep 1: add all lengths of each carpet roll needed
Step2: multiply total length by (1yd ÷ 3ft) = (0.333333) to convert total length into yards
Step 3: multiply total yard length by 4yds (which is 12ft, which is roll width )
Step 4: round up to nearest whole yard

51
Q

How is amount of wallpaper needed calculated with the square footage method for rolls less than 54 inches wide?

A

Step 1: calculate perimeter of the room
Step 2: multiply perimeter by ceiling height to get total sqft
Step 3: add a 20% waste factor to total sqft (multiply sqft by 0.2)
Step 4: calculate the area not being covered I.e. doors (15sqft) windows (15sqft for 2 windows)
Step 5: subtract area not being covered from total sqft
Step 6: divide the area per roll (27in roll has 36sqft - double roll has 72sqft) by step 5 sqft total , round up to nearest whole number

52
Q

How is the amount of wallpaper with a pattern repeat installed with a half.drop match

A

Use the same steps as the sqft method for rolls less that 54” but use a modified Cri,ing height based on the repeat dimension

Step 1: divide the height of wall in inches by distance it the pattern repeat in inches, round to nearest whole number
Step 2: multiply step 1 by distance of the pattern repeat in inches to get the modified ceiling height
Step 3: multiply modified ceiling height by room perimeter
Step 4: add 20 percent waste factor (step 3 x 0.2)
Step 5: calculate area not covered
Step 6: subtract area not covered from total area
Step 7: divide area per roll of wallpaper into the area found in step 6
