Q1. Why, after sealing, does the surface turn white? A1. The sealer is applied when the surface is wet. It appears to be        dry but still contains moisture in the stone or sand joints.        Water and Oil based sealers DO NOT MIX. A2. Over time an over-accumulation of sealer has built up a thick coat.        This thick coat does not allow moisture to escape causing the         moisture to trap between the surface and the sealer. A3. Chemical reaction between sealer and cleaning products that        have not been properly rinsed. A4. Drainage problem. Water or moisture is trapped beneath the        stone and base. This tainted water/moisture evaporates through        the brick causing a whitening of surface.	Q2. How do you solve this problem of whitening or blushing? S1. Obtain Seal King's Laquer Thinner. S2. Apply over tainted area with roller or pump sprayer. The        tainted sealer will disappear. Repeat process if necessary.        DO NOT USE WITH WATER. S3. If problem persists, then using a scrub brush, scrub Laquer       Thinner onto sealer and remove excess material with a rag,        shop vac or pressure washer. WARNING, using a pressure        washer may cause splashing or spilling onto other areas.
Q3. What is Efflorescence? A. Efflorescene is a bi-product of calcium oxide (lime) and water.  When     moisture evaporates the white haze of efflorescence becomes visable.     It is a condition in all cement based products and although the condition     may be minute or severe, it usually corrects itself overtime with exposure     to the environment.	Q4. How do you clean Efflorescence? A. Use Seal King's Efflorescence cleaner and follow     directions as printed on the product label.
Q5. Can I apply Seal King products over other sealers? A. Yes. It can be applied over other sealers but please remember water      based sealers cannot be applied over oil based sealers. Always test      sealer compatibility in an inconspicuous area prior to application.	Q6. What temperature can I apply sealer? A. Ideally temperature should be above 7º celsius.
