Now that you know which stone veneer product yous want to use, you lot may be asking yourself: "How do I install stone veneer?" Don't worry! We've got you covered. Below are our step by stride guide to help y'all learn how to traditional stone veneer istallation and also a tight-stack stone installation. The post-obit is a wide outline for installing Bandage Natural Stone.

Traditional Stone Wall Installation Guide

General

Careful and proper installation is of import for ensuring the long-lasting beauty of your Cast Natural Stone. For all exterior applications, required installation includes a scratch coat (as well known every bit cement plaster blanket) over a water-resistive bulwark. The h2o-resistive barrier by and large consists of two layers of properly applied Grade D paper, which is then covered with metal lath and a mortar scratch coating (cement plaster).

Installation over rigid sheathing:

The metallic lath/scratch coating may be applied over structurally sound wall surfaces of plywood, OSB, concrete board or gypsum capsule, supported by forest or steel studs, and over physical or masonry walls.

Stride one: Surface Preparation

Use 2 layers of Grade D weather condition resistant building paper or equivalent over rigid sheathing. Install from the bottom upwardly ensuring upper layer laps lower at to the lowest degree four inches. Weep screeds should be installed at bottom. [Flashing, as applicable by building codes should be installed at all sill, window and other wall penetration junctures] Important, exist sure that all weep screeds and flashings are installed properly.

For the metal lath, attach ii.five lb. expanded, galvanized, metallic lath to each stud vi" on heart-vertically, penetrating the studs at least one inch. Be sure to attach the lath horizontally. The surface should feel rough as you rub your hand up. Install lath with a minimum 1" overlap on horizontal and vertical seams. Lath on inside and exterior corners should be wrapped completely around the corner to the side by side stud and attached every 6".

Annotation:
Before nailing downwards lath, be sure building newspaper is installed smooth. Board needs to exist tight; any bubbling should exist nailed or stapled downward to forbid "bounce".

Special Note for Concrete and Masonry Surfaces:
Stone Veneer tin be installed direct to clean, unpainted or unsealed brick, concrete block or poured physical surfaces (interior or exterior) without requiring the utilize of metallic lath. On previously coated surfaces, sandblast or waterblast to thoroughly make clean. Where thorough cleaning is not possible, install metal lath and employ a scratch coat application.

Special Notation for Interior Applications:
Aforementioned installation techniques apply, though flashing and weep screeds may not be necessary.

Pace two: Scratch Glaze Application

All lathed surfaces should be covered with a 1/two" to 3/4" coat of Type Northward, or Type S mortar and allowed to ready approximately 30 minutes prior to installing stones. Then brush with a soft bristled brush (to roughen upward surface to ensure a stronger mechanical and chemical bond.). Typical mortar mix consists of one function type "North" or "South" cement and 2.25 parts sand. Mix with enough water to achieve a workable consistency. The same mortar mixture is used for scratch coating, setting the stone and grouting the joints. Dry out pre-mixed mortars, especially designed for masonry, may too exist used. Enquire your Menards representative for specific product recommendations and mixing instructions.

Step 3: Rock Layout and Organization

Before stone installation, lay out a quantity nigh the piece of work area. Alloy multiple boxes to ensure a proper mix of size, shape, texture and colour of stones allowing yous to arrange the stones in the near pleasing design. And then use stones, mixing colors randomly.

Stride four: Awarding

"Butter" the rock past applying an even, 1/2 inch thick layer of mortar to the back of the stone. Be sure to cover the unabridged back of the stone with mortar. Printing the rock firmly into place so that the mortar behind the stone squeezes out on all sides. Utilize a jerk action while applying the stone to insure a good bail. When applying to make clean, concrete and masonry surfaces, dampened the wall prior to installation. This volition assistance adhesion to the existing surface. Adhesion tin can as well exist improved past adding a liquid bonding agent to the mortar mix.

Tip: Install the corner stones first starting at the bottom and working up. Install the remainder of the wall from the top down. This aids in keeping the stone face clean of mortar.

Remove mortar from rock face up, every bit necessary, during installation. Permit mortar to go "crumbly", then remove with a trowel or brush. Exercise not allow mortar on rock surface to dry out overnight.

When necessary, stones can exist cutting and shaped with a masonry hammer, masonry saw or nippers. Position cutting edges away from view when possible. Trimmed edges are easily concealed at grouting.

Step five: Grouting the Joints

Afterwards the stone has been applied to the surface, fill a grout pocketbook with mortar and every bit in decorating a block, fill up the joints with mortar. Grout bags are bachelor from your supplier. While grouting, be certain to comprehend whatever noticeable broken or cut edges with mortar.

Step six: Striking the Joints

When the mortar joints become house, apply a wood or metal strike tool to push the mortar into whatever cavities or voids creating a seal effectually each stone. Any holes, gaps, or voids must be filled in with mortar to prevent water or pests from occupying the space. Use a tuck pointer or similar object to make clean the edges of each stone to foreclose cracking of the grout. Use pressure level to force the mortar into the joints. This volition thoroughly seal the joint edges. Exist careful not to work the joints too soon. This volition crusade the mortar joints to smear.

Step seven: Brushing

Brush the mortar joints with a modest whisk broom to shine and clean away any loose mortar.

Practise non wash off with articulate water. This will result in a milky residue. Brush off whatsoever mortar spots from the face up of the stone veneer. If desired, use a balmy vinegar and water solution to remove whatsoever remaining mortar spots. Loose mortar and mortar spots should non be allowed to dry overnight.

Step 8: Completion & Cleaning

During the stone awarding remove all mortar on the confront of the stone by allowing the mortar to set-up until crumbly, then remove with a dry bristle brush. Exercise not permit mortar on stone surfaces to dry completely.

To remove dirt, smoke or other stains, employ a mild solution of granular detergent and water. Scrub with a bristle brush and rinse with fresh h2o. Do not use wire brushes. Practise not utilize acrid, salt or other "de-icing" materials. They will cause harm to concrete and masonry materials. Cast NATURAL STONE is not warrantied confronting deterioration or discoloration caused by acid, common salt or other chemical or cleaning agents.

*NOTE Almost SEALERS: Sealing exterior stone with any type of sealer type is not recommended. Sealers can trap moisture within the stone, causing stone impairment. Still, if you lot choose to use a sealer, it must exist a high quality "breathable" masonry sealer. Be extremely conscientious to follow the manufacturer's recommended application instructions. Test several unused pieces before general application - some sealers may alter the appearance of the masonry. Practise not use in heavier than recommended coverage – more is not better. Whatever non-breathable sealer is likely to harm the stone and voids the warranty. Failing to precisely follow application instructions for any breathable sealer likewise voids the warranty.

Typical Sill & Lintel Installation

Determine the height at which you would like the top of your sill or lintel. Subtract 2.5" to compensate for sill and lintel meridian. Snap or draw a plumb line at this superlative. This will give you a reference line to work from.

Spike ii"x2" zinc coated angle "Fifty" brackets so the peak is affluent and level with your reference line; apply 3 brackets for every sill/lintel piece to residue on. Employ iv brackets for 48" lintel.

Mortar the dorsum of the sill/lintel and apply to surface allowing it to rest on the angle brackets

Caulk the joint along the back of the sill/lintel and the building. And then cover it with flashing

Continue installing the rock underneath the sill covering the legs of the "L" brackets. Grout and cease the joints.
