New concrete can be applied over Weld-Crete® when it is dry to the touch, usually within one hour, up to ten days later, provided that the Weld-Crete® film is kept clean.

Weld-Crete® can be applied by brush, roller, or spray. Do not dilute. When using spray equipment, the nozzle should permit a fog-type spray. Weld-Crete® should be applied in a thin, continuous, film. Do not permit Weld-Crete® to puddle in low areas.

Weld-Crete®, the original chemical bonding agent for concrete, is a safe, easy to use surface applied bonding agent that bonds new concrete to any clean, structurally sound surface. It has been specified and used by major architects, engineers and construction companies throughout the world since 1952.

Only the base coat is bonded to Weld-Crete®. The base coat should be a minimum of 3/8". The base coat must be allowed to dry 24 hours before the finish coat is applied to prevent flooding of the bond line.

The Engrave-A-Crete? process can be used walls, ceilings, and concrete steps including risers and treads.

Weld-Crete® is applied as a liquid and as it dries to a thin, flexible film, it forms a tenacious bond to the structural surface. The dry film is reactivated by the moisture and chemical reaction that occurs as the new concrete cures. Full bonding strength is achieved after the new concrete has completely cured.

Yes. Weld-Crete® becomes thicker in colder weather and coverage is reduced. Spraying becomes extremely difficult in cold weather. Do not apply in freezing weather. Do not apply over frozen surfaces.

Weld-Crete® may be applied to any clean, structurally sound surface. Weld-Crete® may be applied over painted surfaces provided the paint is clean and well secured to the substrate.

The surface must be clean and structurally sound. Dust, dirt, oil, grease, wax, loose paint, efflorescence, rust, mildew, and other foreign material must be completely removed. Weld-Crete® may be painted over painted surfaces provided the paint is still well secured to the substrate.

No. Weld-Crete® is freeze thaw stable; however, it is preferable to prevent freezing. Allow frozen Weld-Crete® to thaw at room temperature.

The general rule for DS is that it can be applied as soon as you can walk on the finished concrete without leaving a track. Generally, on concrete outside, the time required after finishing is usually about 12 to 24 hours. For concrete that is poured inside, as in a building or under roof, the time required may be longer than 12- 24 hours. Concrete that is poured inside takes longer for the excess water to come up out of the concrete.

Once the new concrete is fully cured, Weld-Crete® is unaffected by humidity or condensation. It is not intended for use as a water barrier. It is not recommended for use where hydrostatic pressure is present.

Wet Weld-Crete® is easily removed with hot water. Dried Weld-Crete® is much more difficult to remove. Chemical solvents such as acetone, methyl isobutyl ketone, or cyclohexanone may be used.

Yes, Decorative Concrete of Maryland’s overlays are applied to any stable concrete slab or wood substrate.

It's a coordinated action where the operator is guiding and propelling the engraver and in turn the engraver and the tracking system are guiding the operator. The pattern is cut into the concrete with a unique diamond saw blade mounted in the engraving machine.

Begin by grinding the repair area down to bare metal and cut the damaged or rusted metal completely away with a tin snips or air cutoff tool. Create a flange at the edge of the newly cut metal so the new panel will fit flush to the surface of the old metal. You can make a flange using a flanging tool or even a pliers. In many cases you can skip the flange and lay the new metal flat on top of the edge of the old metal. But for outer panels, a flange works best.

Color may be added to concrete by adding pigments-before or after concrete is place-and using white cement rather than conventional gray cement, by using chemical stains, or by exposing colorful aggregates at the surface. Textured finishes can vary from a smooth polish to the roughness of gravel. Geometric patterns can be scored, stamped, rolled, or inlaid into the concrete to resemble stone, brick or tile paving.

XYPEX is designed to penetrate and react with the mineral constituents of cement-based materials. It can be applied on concrete, concrete-block, cement stucco or the mortar between bricks.

Yes, XYPEX can be applied to concrete floors. Smooth floor surfaces should be roughened to "open" the porosity and permit the penetration of XYPEX's active ingredients.

A vast amount of water can be trapped by concrete floors below ground. Since the soil adjacent to the concrete can bring humidity to the floor, it is important to avoid direct contact between the laminate flooring and the concrete floor.
