Cleaning myths

Sealing a surface with a SealX impregnating sealer will make the surface water and stain resistant, but not dirt resistant. The sealed surface should be cleaned as regularly as a non-sealed surface. If a problematic substance such as sticky tree gum falls on the surface, it will still be difficult to clean off, but should not permanently stain the surface.

How can i get a maintenance free surface?

Even an impregnating sealed surface will mark. To obtain a maintance free surface you will need to use an epoxy or polyurethane surface topical coating or use a vitreous tile. However, surface topical coatings do have a number of draw backs including; they do not breathe and so trap unsightly water vapor under the surface, they have to be removed when recoating, eventually peel, are often very expensive to install and they significantly change the look of the surface.

CAN't I JUST USE BLeACH?

Cleaners that have the strongest smell include sodium hypochlorite bleach based cleaners. Sodium hypochlorite, a liquid bleach with several uses such as chlorinating pools and purifying drinking water (depending on the dilution), is a corrosive chemical that can cause skin and eye irritation and burns upon contact. It can also produce corrosive gases if mixed with other household products such as toilet cleaners. According to a study published in the American Journal of Respiratory and Critical Care Medicine, frequent use of common household cleaning sprays (at least once a week) may be an important risk factor for adult asthma. In addition, research published in the British Medical Journal's Occupational and Environmental Medicine found the process of cleaning with bleach could generate volatile or airborne compounds that could damage the lining of lung cells, sparking inflammation and making it easier for infections to take hold. They also suggested bleach could suppress the immune system. Fortunately, SealX offers effective cleaners that do not contain any traces of chlorinated bleach.

I ALREADY HAVe A SEALER CAN I APPLY ANOTHER ONE OvER IT?

Yes, but you will need to wash the surface with solvent such as methylated spirits or better still acetone and use a solvent-based surface sealer. The reason for this is because only a solvent-based surface sealer will adhere to an impregnated surface

WHY IS IT EXPENSIVE?

The price reflects their high active content (i.e. the chemicals that do the work) - in some cases up to 100% is active - and the cost and high quality of the ingredients. When economics is the overriding factor of choice then we can offer some less expensive Sealx sealant, yet its performance is outstanding. We understand that our sealers may not suit everyone but whether you use our products or some other reputable business - please make sure you seal!

HOW DO I CALCULATE HOW MUCH I NEED?

To determine how much sealer you'll need, measure the length and width of the area to be sealed. The amount of sealer used will depend on the particular material being sealed. For example, to seal a wet-poured cement-based paver you will need 1 litre per 7 sq.m. (1 quart per 70 sq.ft. per quart) and for sandstone you will need 1 litre per 4 sq.m. (1 quart per 40 sq.ft. per quart). Typical total application rate.

CAN A SURFACE BE SEALED UNDER WATER?

Our products are not recommended for surfaces constantly underwater. The reason is that they work by stopping capillary suction and under constant water pressure the repellency is overcome and water penetrates via permeation and diffusion. The time it takes to overcome the repellency depends on the pore size of the stone and the water pressure. With a one metre pressure head it could take treated concrete 18 months but with 3 inches of water over porous bricks it could be days. Having said all that, if the stone is exposed to the air and allowed to dry regularly the repellency will be restored and the 'clock' starts again.

An alternative is a clear epoxy coating, although epoxies have a lot of other problems.

WILL IT STAIN AFTER SEALING?

This sometimes occurs when excess sealer has been left on the surface. If the sealer is less than a few days old the residue can be removed by applying some of the sealer to a dry white cotton towel and polishing the residue until the surface is clean. This should dissolve the residue. If the residue has dried then applying some of paint stripper to a dry white towel and polish the residue until the surface is clean. A nylon-scouring pad may also help remove really stubborn residue.

WHAT MAINTENANCE IS reQUIRED?

The long-term good looks of a sealed surface will depend on maintenance. Removing spills immediately, using diluted bleach to remove marks and routine cleaning and scrubbing of the surface will keep surfaces looking good for longer.
