Surface Products

Are thick coats of surface products better than thin coats?

Thin coats are always better than thick coats. This will promote better adhesion of the product.

Why are little blisters or bubbles appearing on the concrete surface where a sealer was applied?

Blisters or bubbles appear on the concrete surface when the Cure & Seal dries too fast and does not have a chance to permeate into the concrete surface before premature drying occurs. Premature drying of the Cure & Seal product does not allow proper cohesion characteristics to form between the concrete surface and the Cure & Seal product. High ambient temperatures and wind can cause this to happen. Try to apply Cure & Seal when ambient temperatures are lower with little or no wind. If necessary, diluting Cure & Seal with Russolve 100 at a 1:1 ratio will assist you in applying the Cure & Seal during high ambient temperatures. Blisters or bubbles on the surface can also be remedied by rolling Russolve 100 on the concrete surface where blisters or bubbles are present, then allowing it to dry again.

Why are there white milky-looking spots on the concrete surface where a sealer was applied?

These spots are the result of moisture present in the concrete that has mixed with the Cure & Seal. Always make sure concrete surfaces have dried for a minimum of 24 hours before applying Cure & Seal. This problem can be remedied by rolling Russolve 100 on the surface and letting it dry.

Why is the Cure & Seal cracking, flaking up, or curling?

When concrete surfaces have too many layers of Cure & Seal, the layers will begin to delaminate. This condition can also be caused by previous layers with poor adhesion. Sometimes rolling on Russolve 100 or a 50% dilution of Russolve 100 and Cure & Seal will remedy this situation. If this doesn’t remedy the problem, all the Cure & Seal must be removed before recoating.

Why has the Cure & Seal coating turned yellow?

This usually occurs when coating has been put on too thick. This problem can be remedied by rolling Russolve 100 on the surface and letting it dry.

Can I put RussTech sealer over an old sealer?

Cure & Seal products can be recoated with the same product after proper surface preparation. If recoating with a different product or brand, the old coating must be removed before application or tested to be sure the old coating is gone.

What is the best possible protection for a concrete surface with RussTech surface products?

The best system for surface protection is one coat of Silicaseal-W followed by two coats of Stampseal 30.

What is the longest lasting Cure & Seal supplied by RussTech?

How long does normal Cure & Seal last?

Usually 12-18 months. They dissipate over this time from exposure to UV rays.

What can I do to arrest a concrete surface that is dusting?

Apply several coats of Silicaseal-W. Let it dry between coats.

Does RussTech have a penetrating sealer?

Yes. SilicaSeal-W is a penetrating sealer.

What is the correct procedure for recoating Cure & Seal on an old surface?

When is the correct time to apply Cure & Seal on newly placed concrete?

On new concrete surfaces, apply when surface water glazing or sheen has disappeared and finishing is complete.

What can I do if the concrete surface is slippery?

Incorporate RussTech Nonskid Grit with the Cure & Seal application.

How can I prevent crusting and drying shrinkage cracks from occurring while finishing concrete?

EVRT, evaporation retardant, is ready to use and will reduce or eliminate surface evaporation which causes crusting and drying shrinkage cracks.

How do I remove an old Cure & Seal coating?

This is an unpleasantly tedious process. Russolve 100 or SealerStrip 200 must be used to soften the old coating, then power washed off in small areas at a time while old coating is soft.
