Curing, particularly within the first few hours after

concrete placement, is one of the most important

factors in manufacturing top quality precastconcrete products. Properly cured precast

concrete will achieve both superior early strength

and long-term strength. Properly cured precast

concrete products are also less permeable, more

durable and display greater surface hardness.

In addition to a good, high quality mix design,

proper curing is essential. Concrete hydration

occurs in stages. The first three phases occur

within the initial 10 to 20 hours, and involve a

releasing large amount of heat during the

hydration. Stage four will primarily occur over the

first few days, but continues for weeks. Actually,

as long as concrete has access to moisture, the

curing process of stage four will continue.

Concrete that is exposed to air at an earlier stage

will have a lower strength and an increasedporosity. The chart below shows how significant

this effect is.

UBOND Shield is a unique liquid penetrant

comprising a VOC free NANO SILICA base with an

extremely small and spherical molecular structure.

When applied via an airless sprayer UBOND Shield

to the surface of porous concrete it completely

fills the matrix capillaries and penetrates the freecement particles in the concrete to increase the

hydration of the concrete thus improving the

strength and surface hardness of the concrete

matrix.

In this way it provides a permanent moisture

barrier up to 200 mm deep, it prevents the ingress

of chloride ions that cause or continue rust in the

embedded steel, and when applied to a newly

poured green slab, it delivers a curing medium

equal to, or better than 28 day water ponding in

less than one day.

Unlike surface sealers or membranes, UBOND

Shield provides a permanent solution for the

curing, waterproofing, rust mitigation, immunityfrom salt and chemical attack, densification,

hardening and strengthening of concrete in one

application replacing traditional processes and

products associated

with the treatment of placed concrete slab floors,

walls and Portland cement based concrete

products.

Strengthening

When applied at the time of pour, the active

blocking of the capillaries and increased

hydration of the adjacent cement particlesincreases the flexural and compressive

strength of the concrete. As a result, the

effects of slab curl and edge curl are

eliminated

marine environments

Sea Water and salt air are major attack

elements on concrete - UBOND SHIELD

through its pore blocking action together with

surface hardening provides a lifetime

protection of concrete in these extreme

environments. Placed concrete or formwork,

bridge decks, poles etc can be single UBOND

SHIELD treated before immersion

prevents surface cracking

A major problem - especially in hot climates -

of placing new concrete is the surface cracks

caused by excess bleed water rapidly

escaping the concrete surface. Using UBOND

Shield at the time of pour eliminates surface

cracking as the "down and up" action of the

colloidal gel entering and filling the capillaries

forces the excess bleed water out as the gel

fills the capillary. In a very short time the

surface is dry. No more curing membranes to

apply and remove later on.

resistance to chemical attack

The effective and permanent pore blocker

nature of the UBOND SHIELD product also

protects the concrete from chemical attack -

including the ingress of chloride ions that canrust the embedded steel reinforcing in the

concrete matrix. When applied to concrete

with concrete cancer, it can arrest the spread

of corrosion of embedded steel hardening of

surface

UBOND SHIELD produces a colloidal gel

similar to the calcium silicate hydrate (CSH)

which makes the concrete surface harder

thus reducing the effects of dusting especially

seen with lower quality sidewalk concrete.

moisture can attack the polymer coatings bond

during the service life of the concrete. Left

untreated, moisture can cause the coatings to de-

bond from the concrete substrate.

When UB SHIELD is applied to the concrete, it

penetrates as deep as the surface capillaries will

allow. The moisture and high pH is sealed below

the concrete surface where it cannot affect the

coatings or adhesives. Trapping the high pH below

the surface is also beneficial for protecting

reinforcing steel from corrosion.

UB SHIELD deeply penetrates deep into the

concrete, reacts with free alkali in the concrete,

and forms a colloidal gel in the tiny concrete

pores. This results in waterproof concrete that has

been tested to withstand over 100-feet of Head

Pressure (30-meters).

To prevent failures due to moisture problems,

every coating or covering should have UB SHIELD

applied first.

UB SHIELD Benefits:

Normally requires one easy application

Coatings and/or floor coverings can

typically be applied after 24-hours

Odorless

VOC free Environmentally friendly

With new concrete, the pH level is around 12 or

higher - far too high for traditional adhesives and

coatings to work. Due to environmental

restrictions placed on the manufacturing of

adhesives, most will only tolerate a pH of around

9. Most traditional adhesives fail when the pH is

above 10.
