Remove all traces of plaster, paint, etc.

▪

Construction of the masonry must comply with BS

8000-3.

▪

On low suction substrates e.g. shuttered concrete or

high suction substrates e.g. lightweight aircrete or

clay blockwork, first apply a coat of ready-to use MI-

CRO GOBETIS 3000 or a MONOREX GF key- coat

made up by adding 0.5 L of 751 LANKOLATEX to the

mixing water volume for a 25 kg bag of MONOREX

GF.

▪

On wet or wet patchy substrates or where different

materials have been used it is advisable to apply a

key coat made up by exchanging 0.5 L of water for

0.5 L of 751 LANKOLATEX or FIXOPIERRE for the mix-

ing volume for a 25 kg bag of MONOREX GF. Allow

the key coat to fully dry a minimum of 48 hours be-

fore the application of the next coat. This suggestion

will assist against the effect of ‘block ghosting’ and

shade variation.

▪

TV10 MESH may also be required, dependent upon

substrate condition and project specification.

▪

Advisory note

Due to shrinkage differentials, avoid applying a thin

base coat and a thicker top coat application as the

shrinkage values of a thicker top coat could cause

the render to delaminate from the base coat. The

same effect is also caused by applying a very hard

render over a softer base coat.

▪

Always refer to the RAREX® mesh application details.

▪

To avoid shade variations always apply and finish the

render application to whole elevations at the same

time.

▪

APPLICATION

Refer to and comply with the Substrate Preparation

first.

▪

For very severe wind driven rain index locations, high

exposure or coastal zones please contact PAREX® for

additional guidance as the render thickness may

need to be increased and additional surface treat-

ment may be recommended.

▪

SUITABLE FOR

Machine or manual applications.

▪

Ensure the product is mixed correctly with the cor-

rect water content and do not allow the render to

cure too quickly as surface holes in the render could

occur.

▪

FOR WEATHERPROOFING APPLICATIONS TO CON-

CRETE BLOCKS, CLAY BLOCKS, LIGHTWEIGHT AIRCRETE

BLOCKS, BRICKS, ETC.

SPRAY TEXTURED & SMOOTH SPRAY TEXTURED

Apply a level, compact minimum 13 - 15 mm thick

first coat. Allow to dry and then spray the Textured

finish. The Smooth Textured appearance is obtained

by pressing a plastic or stainless-steel float over the

stiffened but not dry Textured finish.

▪

SCRAPED FINISH

Apply a level, ruled compact 18 mm thick coat, level

the surface with a straight edge, spatula or trowel

flat. Allow to dry (3-16 hours) and depending on the

substrate and drying conditions, scrape the surface

in small circular motions using a scraping tool, re-

moving no more than 3 mm from the surface.

▪

This scraping process must remove any slight imper-

fections and bring the application to the specified

finished thickness. Each elevation must be scraped at

the same stage, as early scraping will result in a

slightly darker shade and later scraping in a lighter

shade.The minimum finished thickness after scraping

is 15 mm.

▪

After scraping, any dust on the surface should be re-

moved by brushing with a clean soft bristle brush. Al-

ways stand back and examine the whole surface for

blemishes and unevenness. Errors must be corrected

at this stage as rectification later is not practical.

▪

FOR DECORATING WATERPROOF CONCRETE AND MA-

SONRY SUBSTRATES, I.E. COVERED WITH AN EXISTING

SOUND AND WEATHERPROOF RENDER.

SPRAY TEXTURED & SMOOTH SPRAY TEXTURED

Apply a level, ruled, lined, compact minimum 5 mm-

thick first coat. Allow to dry and then spray the Tex-

tured coat. The Smooth Textured appearance is ob-

tained by pressing a plastic or stainless-steel float

over the stiffened but not dry Textured coat.

▪

SCRAPED FINISH

Apply a level, ruled compact 13 mm thick coat, level

the surface with a straight edge, spatula or trowel

flat. Allow to dry (3-16 hours) and depending on the

substrate and drying conditions, scrape the surface

in small circular motions using a scraping tool, re-

moving no more than 3 mm from the surface.
