- standard durability rollable or troweled deck coating
- what is type 3 nonskid?
- standard durability, rollable resilient deck coating
- where is type 3 nonskid used?
- this coating is used on
1)exterior wooden decks
3)metal decks where flexibilty is required and where increased weight is not a factor
- what is type 4 nonskid?
- standard durability, sprayable deck coating
- flight deck impact areas and catapult tracks (metal decks) aboard carriers require what type of nonskid?
- type 1 or 2, Comp L

- type 1 or 2, Comp G
- helipads (skid configured zones) aboard air capable ships require what type of nonskid?
- type 1, Comp G
- flight decks (metal decks) (excluding carriers) aboard air capable ships require what type of nonskid?
- type 1 or 2, Comp G
- all ships exterior passagewys and interior decks require what type of nonskid?
- type 3
- all vertical replenishment areas, weather decks, exterior passageways, and interior decks require what type of nonskid?
- type 1 or 2, Comp G
- the most effective method of removing nonskid systems, scale, rust, and contamination is by what method?
- centrifugal blasting
- what size profile should be left on the deck?
- 3-4.5 mil profile
- after an abrasive blast how is the surface profile determined?
- by using a replica tape system
- replica tape measurement readings of the surface profile are kept where?
- are kept as part of a permanent record of a nonskid job
- how is the replica of the surface profile measured?
- by the use of a micrometer
- controlling the standard mil profile is dependent on what?
- the size of shot in relation to the speed of the blasting machine
- for application of primer how should the surface appear?
- a near white metal blast cleaned surface is required
- how soon should the primer be applied after the metal is cleaned?
- to lessen the possibility of rusting or other surface contamination the primer should be applied 1 hour after the metal is cleaned
- what is the maxium time allowable to apply primer to cleaned metal?
- six hours
- if primer is not applied within six hours of being abrasive blasted what action should be taken?
- the surface must be brush blasted
- what is hydroblasting?
- the use of fresh water striking a surface to remove the existing coating
- what is the primary advantage of hydroblasting?
- 1)no dust pollution
2)less waste to dispose
4)less disruption of other ship work
- what amendments are the hydroblast facility required to comply with?
- 1)Clean Air Act
2)Clean Water Act
- high pressure hydroblasting operates at what pressures?
- between 680-1,700 bar (10,000 to 25,000PSI)
- what does Ultra High Pressure operate at?
- what are two types of surface prepartion power cleaning tools used for small nonskid repair areas?
- 1)the tennant
- how is it possible to remove old or worn coatings, profile the deck, and clean any residual contaminants by using the descobrder?
- through interchangeable heads
- when using the descobrader controlling the machine for removal of coatings and profiling is accomplished by what means?
- by a counterweight located on the top of the unit
- name two rotary descaler and deck peening apparatuses?
- the tennant and the descobrader
- where optimum slip resistance and heavy wear resistance is required how should the nonskid material be applied?
- roller or trowel
- how should the method of nonskid removal be determined?
- select the fastest method of removal that will cause the least damage to the underlying metal surface
- what is an indication that a area of nonskid surface sould be resurfaced?
- patches of the nonskid are easily removed by chipping or scraping
- what is the cure time of primer?
- generally between 6-12hours depending of the weather
- when repairing small area nonskip how far beyond the damaged area should the deck be scaled?
- 6-10 inches in undamaged nonskid area
- the primer should be mixed per the intructions of whom?
- the manufactuer
- when applying the primer by rolling how should the roller be outfitted?
- rollers should be outfitted with a nap range between 3/4" to 1"
- the target surface profile of properly cured nonskid should be what?
- betwwen 1/32"(minimum) to 1/16"(max)
- what is the typical traffic allowed in relation to the curring time of nonskid?
- 1)foot traffic=24hrs
3)fully cured=after 7 days
- how wide should wheel-stop coaming marking be?
- 12" wide
- bulkhead VLA markings are place how high from the deck and at what intervals?
- 14' up from the deck at 10 frame intervals
- where could you find the standard certification requirements and inspection procedures for VLA marking for aircraft carriers?
- Visual Landing Aids General Service Bulletin No.8
- standard certification requirements and inspection procedures for VLA marking for amphibious ships can be found where?
