Home Slicker Stone & Stucco, our newest Home Slicker product, is the only vertically channeled rainscreen that has been specifically designed for use with manufactured stone, natural stone, stucco, and masonry applications. Each roll contains the patented Home Slicker three-dimensional matrix bonded to a fabric which prevents mortar from entering the wall cavity during cladding installation.

Leading building scientists recommend rainscreen systems be used in areas prone to wind-driven rain and/or areas that have an average annual rainfall of 40 inches or more. Refer to our Whitepaper, Managing Moisture in Residential Building Envelopes, that can be found in the Tips and Training section of our Building Professionals area.

Wind-driven rain from the outside and moisture vapor from the home’s interior, often remain trapped in the sidewall assembly. Left alone, this moisture can promote the growth of mold and undermine the structural integrity of the sheer wall. Prior to the introduction of Home Slicker Stone & Stucco, metal lath was applied directly to building paper providing opportunity for potential moisture problems.

No. Home Slicker Stone & Stucco is used in conjunction with a high quality housewrap or building paper as part of a comprehensive approach to moisture management.

Home Slicker Stone & Stucco solves the moisture problem by effectively draining and venting moisture from behind manufactured stone, natural stone, stucco, and masonry applications.

1. Drainable housewraps are only adequate in regions where wind-driven rain is not a concern and in areas that receive less than 40 inches of rain a year. However, structures being constructed in areas that do receive 40+ inches of rain a year, or are susceptible to wind-driven rain, should use Home Slicker Stone & Stucco to create a rainscreen system.

2.Drainable housewraps are only 18 mils thick at the highest point. Because water can span gaps up to a 1/8 inch [125 mils], drainable housewraps do not provide the necessary capillary break needed to prevent water from bridging at the back of the cladding onto the housewrap. Only a true rainscreen system can accomplish this.

Home Slicker Stone & Stucco should be installed over the window flange after windows have been properly installed.

Home Slicker Stone & Stucco is recommended under trim and corner boards. It is also suggested that each wall section be compartmentalized to equalize pressure which will help to reduce water intrusion.

Although you will not receive the benefit of a fully ventilated rainscreen assembly, Home Slicker Stone & Stucco will still dramatically enhance the drainage and drying capability of the entire wall assembly when compared to a wall that is not ventilated with a rainscreen. Install weep vents at the bottom of the wall to allow air movement and drainage.

Weep vents should be used to allow moisture drainage out of the wall when a shelf exists. Weep vents are intended to be installed vertical in masonry joints between two bricks at the base course. In manufactured stone, cut a notch in the non-woven fabric and push the weep vent into the channels of the Home Slicker Stone & Stucco leaving the fabric over the top of the vent so mortar cannot clog the vent. For stucco applications, use a stucco stop or weep screed with weep holes.
