PREFACE

The following report contains a record of the observations and conclusions reached in a study of an unusual problem of paint deterioration on housing projects in

Vancouverp British Columbiao

This study was carried out at the request of the Central Mortgage and Housing Corpora= tion and is an example of the research into the technical aspects of house construction which the Division of Building Research of the National Research Council looks forward to carrying out for the Corporationo

The Division of Building Research is

most grateful to Dro ｃ｡ｭ｢ｲｯｮｾ Assistant

Director of the Division of Chemistryp for his kind interest in the problem and to Dr o Hopkins of his staff for his active and expert assistance in the investigation and in the preparation of this reporto

The report represents the first step in what will probably be a long-range study of

paint problems and for this reasonp should be

regarded essentially as a statement of progress 0

REPORT ON THE EXAMINATION OF PAINT ON THE EXTERIOR OF HOUSES

IN THE VANCOUVER AREA

(Prepared for the Central Mortgage and Housing Corporation)

The failure of exterior paints on wartime houses under the con= trol of the Central Mortgage and Housing Corporation has presented

a serious maintenance problem for several years o Blistering and

peeling of the paint has taken place within one year after its ｡ｰｰｬｩｾ

cat Lon, This has occurred on houses of new c onst.ru etion and al so on

older houses that have been painted a second and third timeo ｔｾ･

failure of the paint is not localized but rather it is country=wideo Some locations are worse than others but this is also true for ad=

jacent housesp the paint on one deteriorating sooner and to a greater

extent than the paint on the house next to ito

At the request of the Central Mortgage and Housing ｃｯｲｰｯｲ｡ｴｩｯｮｾ

Mr.

National Research Councilp visited the sites of several wartime

houses in Vancouver while at the west coast in ｊｵｮ･ｾ 19480 From his

initial observations made at that timep methods were instituted

immediately upon his return to Ottawa for a thorough study of the pr-obLem, to ascertain the causes for the failure of the pal nt 0

A meeting was held on June 30th at the National Research Council which was attended by Dr. Ao Cambron and Dro Co Yo Hopkins of the

Division of Chemistryp Mr. 1 0 Eo Ashfield of the Central Mortgage m d

Housing Corporation and

Mr

the Division of Building Researeho After discussion of the problem

at this meeting it was proposed that Dro ｈｯｰｫｾｮｳ and Mro Eo Vo Gibbons

visit the houses in the Vancouver area and meke a detailed survey of

their condition during the latter part of July0 As a result of such

a surveyp recommendations would then be made to prevent failure

upon repainting and inClude suggestions for new construction to pre= vent recurrence of the paint failureo

10 Examination of Houses in Vancouver and North Vancouver

Several housing projects under the control of the Central

Mortgage and Housing Corporation at Vancouver and Victoriap British

Columbiap were examined during the period July 19th to 27thp 19480

Peeling of exterior paint on wood siding had occurred on a conSiderable number of these houseso

Particular attention was paid

No records are avaiJable of the date p weather and condition of the wood at the time of painting of any particular house or

group of houses 0 Information supplied indicates that the wood

siding was green at the time the first paint was appliedo During

the period of repainting some houses were wainted under unfavourable

weather conditions o However11 since the failure is prevalent on all

the wood siding houses in this area and since the greater number

were painted under favourable conditionsg this can only be considered

a secondary cause for failureo All painting operations are re=

ported to have been done by spray methodso

Houses located at Sea ｉｳｬ｡ｮ､ｾ Victoria and Esquimalt were also

examined" Some blistering and peeling of the paint had occurred

in each location but not to the extent that i t had in North Vancouver 0

In most instances failure is confined to the lower area of the walls near the floor-line or immediately below the windows

Although the site at Sea Island is low, the drainage is better

Montreal

Five houses of the Central Mortgage and Housing Corporation

located at 14009 1401, 1415, 1425 and 1435 Jolicoeur Avenue in

Montreal were examined on July l7tho These houses were painted

by spraying with one coat of the Abbott Company IS No. 188 paint

The houses are wood frame construction9 set on concrete

foundations 0 A full basement has been provided but no concrete

floors have been placed in them0 Three of the houses are

finished with narrow cedar siding and the other two are finished with wood shingle s Ld Lng , The houses are type ｈｾＱＵ

and H=16o The attics in all of the houses are vented in the

gable endso

The houses were painted during the period June 22=290 The

condi tion of the paint on the wood shingle d houses was very goo d

while the paint on the cedar siding houses was pocr-, 'I'her e were

numer-ous bl isters and breaks on walls of the house with cedar

siding0 This may be due to improper preparation before painting

(by not removing all loose p af.rrt ) , Adhesion of the paint was

good' when the under--oca t ·was' firm arid vilere bare wood was

painted" As the se houses had been painted less than a month

previous to this exsmf nati on, it is too early to exj.res s an

opinion on weathering properties 0 It is suggested that the

paint be observed periodically during the first year o 40 Miscellaneous Factors ａｦｦ･｣ｴｩｮｂＭｐｾｅｴｩｮｧ

She｡ｴｨｩｾｐ｡ｰ er s

Samples of the sheathing paper were obtained from severaL

houses in each projecto In many instances" it was observed that

where wet spots (24 per cent moisture) were present in the

sidingj) the ,outer side next to the sheathing paper was very damp

while the side next to the' sheathing was dr-y , No damp at.uddf.ng ,

sheathing, or gyproc wall board was f'o und , It has been ascertained

that the bUilding papers are suitable for the use that has been

made of them₉ although some are more resistant to the transfer

of moisture vapour than otihe r-s ,

No samples of the sheathing papers obtained can be classed

Quality of Paints Used

Samples of the paint coating were taken from two houses

in North Vancouvero On ｡ｮ｡ｬｹｳｩｳｾ the pigments were found to

consist of a lead=zinc-inert mixture but the content of inert ingredients was higher than is usually considered de-sirable in a first grade painto

As these houses had been painted ｴｷｩ｣･ｾ the samples taken

of the coating represented the sum of the constituents of tWJ

different paintso There was no record available of the source

of these paint.s or of any previous inspection or ar&ysiso

Accordingl" no advantage was seen in foDbwing up the matter of

composition of paints already usedo It may be saidp ｨｯｾ･ｶ･ｲＹ

that a higher quality pigment mixture would be desirable for use under the adverse conditions prevailing in this area o

ｾｩ｣｡ｴｩｯｮ of Paint

The paint coatings examined had been applied by spray and

were reasonably unifor.m and smootho Some runs and sags were

ohserved p these are difficult to avoid entirely in spraying ell :'.int0

The thickness of the coatings was measured and found to

be greater than normalo Sample 9995 was 13 mils thick and

sample 9996 was 9 mils thicko Normal dry film thickness is

about 2 mils per single coato A coating 13 mils thick is

considerably ｡ｾｶ･ the optimum for satisfactory serviceo

Mildew

Many of the houses showed a patchy discoloration over large areas of the exterior walls Which is suspected to be the result of mildew (fungus growth) 'on or underneath the paint

filmo Mildew is a common trouble on exterior painted surfaces

in very damp climateso It is objectionablep not only because

of the appearance₉ but ｢ｾ｣｡ｵｳ･ it may cause cracking or peeling

of the painto ｃｯｮｳｩ､･ｲ｡ｴｾｯｮ shoQld be given to methods of

mildew prevention when formulating paints for this regiono 50 Summary and IO':'£.1'!!;.;.endations

The basic cause of peeling in this case is jUdged to have been the presence of large quantities of moisture under the sidine sometime after paintingo

ｾ 21 "'"'

It i8 believed ｴ｢ｾｴ the moisture came ｦｾｯｭ at least two

source"g vizo (a)' from damp ground and ground waters> aggr

a-vated by rain water lying ｵｮ､･ｾ the house-and (b) from

cookingg washing and other sources within the house o This

factor is intensified by the presence of a relatively large

number of personss> includIng children in houses of small volumeo

A possible third souroe of moisture ｩｾ penetration of

rain through the joints in the sidingo This probably acqounts

for the severest peeling on the ｾ｡ｳｴ sides> which is said to be

subject to the prevailing windso

While anyone of these sources of moisture might be

in-sufficient to cause the damage ｯ｢ｳ･ｲｶ･､ｾ the accumulated

moisture from all sources is believed to be responsibleo

A secondary cause is probably the application of the paint

on damp siding in wet weathero Various persons stated that

painting had been done under such unfavourable condition on these Projects0 '

In some cases examineds> the paint coating was fcund to exceed the thickness usually recommendedo

ｾｴ･ｲｮ｡ｴｩｶ･ Solutions

In order to overcome the difficulty of paint peeling on existing housess> the following alternatives are possibleg

(a) Cover the side walls with shingles and treat with

stain or painto

(b) Remove the siding Sld replace by rough siding;

treat with staino

(c) Correct conditions leading to moisture accumulation

(as far as possible) and repaint while dryo

If alternative (c) is chosens> the following recommendations are

ｯｦｲ･ｲ･､ｾ

10 Structural ｡ｬｴｾｲ｡ｴｩｯｮｳ

(a) Install additional ventilators in the crawl space

beneath the houses> to provide a minimum of four

8- by l4-inch openingso

The openings should be close to the corners rather than at the centres o

.,,22=

(b) Install attic vents. one in each Igable en d ,

close to the :r:eak, The total area of the

opening s should be not LesS than ,2 square

feet for each house o

(c) Arrange a drain to divert the water from the

downspouts away from the house,

(d) Install a damp course or wea tne r--c ap between

the 2- by Lo-Tncn gr-ourid board and the boar-ds

above 0

(e) He-nail any pieces of siding which do not mal.e

tieht joints wi til the adja cent boards, This is

to prevent rain from entering th e wall thr-ough

the jointso

(f) Level the earth in the crawl space and eliminate

any conditions which would prevent ground water

from draining away0

(g) Maintain or improve surface drainage so that

ground water cannot remain under or near the hous eo

20 Details of painting:

(a) Use paint from a supplier on the approved list,

(b) Remove all Loc s e and scaling paint, preferably

by the use of a blow torcho

(c) Make sure that the siding is dry before paint ing

Determine the moisture content by means of the

electric moisture meter, testing at least four

places on each wallo If the moisture content is

14 per cent or lesss the wood is ready for painting0

(d) Apply the first coat on bare wood by br-ush , The

second co at may be a pp Lfe d by brush or spray The

second coat must be applied under dry conditions

as described in paragraph 2 (c/o

(e) Apply coats of normal thickness, that is,. appr-oxl«

mutely 2 mils per single coat (1 mil == 1/1000 inch;"

Avoid bu Ll.d.i ng up undUly thick co at Ing s 0

R,commendations for New Construction

ｾ･ following recommendations are offered for adoption in

future ｣ｯｮｳｴｲｵ｣ｴｩｯｮｾ

10 That a minimum of 1 square foot of opening per 15 lineal

feet of surrounding wall be provided for crawl sPace ven= tilationo

20, That a minimum. of 50 square inches per 100 square feet of

ceiling area be provided for attic ventilation"

30' The earth 1n the crawl space should be levelled and covered

ｷｾｴｨ 2 to 3 inches of loose fillo

40 A damp course be placed between sills and concrete

founda-tion o This is also recommended for hcuses that will have

concrete foundations put under them in the futureo

50 That the rainwater from downspouts be diverted from the

foundation by drains or splash blocks 0 The ground surrounding

the basements should be sloped a quarter of an inch per foot

for a distance from ato 10 feet from the wallo

60 That a vapour barrier be placed on the inner side of the

framing of exterior wallso

70 Paper applied between sheathing Sldsiding should be

ordinary building paperj) permeable to water vapour ,

80 That the siding should be applied with particular attention

in getting tight joints in order to exclude wind=driven

raino Tongued and grooved siding may be preferableo

90 Projecting eaves are desirable as they protect the wall

to some extent from sun and rain and add to the durability of the paint0
