| Efflorescence is a water soluble salt that appears on the face of all
types of masonry products. It is caused from water that has penetrated the
wall, and is evaporating back through the face. Rogue River Stone has had
very little problem with efflorescence. But if it does occur, it can be
removed easily after the stone is dry. Using clean water and a scrub brush,
(never use a wire brush on veneer stone) scrub vigorously, then rinse with
clean water. If this does not remove all of it, try mixing 1 part white
vinegar to 4 parts water, scrub and rinse again. If this doesn’t work see
your local dealer. Remember that anytime you are using anything other than
water to clean, wet the wall first. |

| Cracking sometimes occurs in veneer stone. This is usually caused from
settling. Settling does not always mean that the foundation is sinking, but
just the wood framing itself. Quite often the stone is installed on
buildings as soon as they are framed, before the roofing and sheetrocking is
completed. As these things are completed the added weight will sometimes
cause the framing to settle a little which can cause the stone to crack.
This occurs more often when OSB is used so we recommend that these be
completed before the stone is installed. Also, make sure that you follow the
manufacturer’s installation instructions of the stone. Cracking occurs most
often on corners when they are not double wrapped. |

| Occasionally you may have stone that does not look the same as the
sample when you are installing it. Most of the time it is because the sample
board is cured completely and the stone is still curing. It takes about 30
days for the stone to cure if the weather is good, up to 120 days if the
weather is damp or cold. If you want to make sure that the colors will be
the same put a couple of the stones near a heater or in your oven at 150
degrees for about 8 hours. Setting it out in the sun will not always dry it
quick enough. |

| If you are having problems with the stone not sticking to the wall it is
normally because your mortar is too dry. Try wetting the mortar a little
more. If the stone wants to slide down when you take your hands away the
mortar is too wet. If you are drystacking the stone we recommend you add a
bonding agent to your mortar. |

| If the grout is drying too fast you may need to add more water to the
mix, grout a smaller area, or dampen the wall a little. If the grout is
drying too slowly you may need to put a heater in front of the area, enclose
the area with tarps, or add something like fast set to make it dry quicker.
Ask your local dealer for his recommendation. |

| If you are having problems getting stone to stick when you are applying
them upside-down, make your scratch coat in that area smooth, then only
apply mortar to the outside edge of the stone leaving a hole in the middle.
This will create a suction and should help. Again, this only applies to
stone you are installing upside down. For all other applications follow the
regular installation instructions. |
