Product title: Renderpol

Valid from: 13th January 2000

Last reviewed: May 2019

Type: A general-purpose two or three pack epoxy filler, type: a two-pack cold cured
polyester screed, filler and repair compound.

Suggested use

As a re-surfacer and repair compound for concrete, brick
and metallic substrates. The product may be used with
reinforcementmesh where necessary to ensure the integrity
of severely damaged components and as an aid to bonding.
Typical areas of work include pit filling, drain interceptors,
gullies etc.


Not suitable for immersion in some highly polar solvents,
demineralized water,extremes of pH values orimmersion
temperatures above 122°F (50°C).

Health & safety

Before handling or using this product, the material safety data
sheets should be read, and all precautions observed.

Surface preparation

Dependent upon application and usage: Concrete substrates
should generally be prepared in accordance with data sheet
SP5 but other methods may be applicable, please consult
Corrocoat USA. For best results on metallic substrates,
these should be grit blasted to SSPC-SP10 (IS0 8501-1 Sa
2½) or equivalent with a minimum 2 mil (50micron) profile
and primed. This product should preferably be applied over
PPA primer or the first coat of other Corroglass/ Polyglass
series material.
Where normal preparation procedures are not practical and
bonded reinforcement mesh can be used, it is acceptable to
apply the Renderpol directly on to the surface provided the
surface is clean, free from water and dust. This is typical of
interceptor work where in effect, a tank within a tank is built

Application equipment

Stiff Brush or trowel or scraper blade.


Weigh out only the proportion of material that can be used
within the pot life and place into a mixing container. Measure
the correct proportion of catalyst for the amount of base
and carefully add this to the base using a suitable clean
implement. Mix thoroughly then add dye if required and mix
to an even color. After stirring it is essential to remove the
contents from the mixing container into a shallow receptacle
and remix.

Catalyst type

Use catalyst P2 or below 50°F (10°C) for best results use
catalyst P4.


Using a trowelor stiffbrush, the catalyzed material should be
vigorously worked into the surface profile, ensuring that the
maximum possible surface areais wetted out.Following wet
out, the coating thickness may be built up using a stiff brush
or trowel.The material may be applied at DFT’sof up to 6mm
withoutsagging ona vertical surface.Materialmaybeapplied
up to 20mm when used as a grouting compound at and below
68°F (20°C).Wire mesh should be used as reinforcementin
severely damaged areas or when rebuildingwork is required,
laminating or otherreinforcementtechniques maybe used as

Pot life

55-65 Minutes at 68°F (20°C). Pot life will be shorter at
higher temperatures and longer at lower temperatures.

99.8%. Regular surfaces, e.g. new steel – 25 sf per gal at 40 mils
DFT (1.9kg/m² @ 1mm DFT). Irregular surfaces, e.g.
pitted steel – 15 sf per gal at 40 mils DFT (3kg/m² @ 1mm

May take place as soon as the previous coat has gelled
sufficiently to resist movement of next application and while
still tacky.Maximum overcoating without treatment is 4 days
at 68°F (20°C) (shorter at ambient temperatures above
86°F (30°C).

Cure time

At 68°F (20°C), 90% cure will be attained in 8 hours. Full
cure for chemical resistance will require 6 days at 6°F
(20°C). Cure times may be shortened, and the degree of
final cure improved by post curing at elevated.
