<p data-start="253" data-end="459">At a <strong data-start="258" data-end="280">3 mm bed thickness</strong> (thin-bed application), you’d typically get about <strong data-start="331" data-end="354">4 kg/m² of adhesive</strong>.

<ul data-start="498" data-end="832">
<li data-start="498" data-end="634">
<p data-start="500" data-end="634">Coverage decreases as <strong data-start="522" data-end="549">bed thickness increases</strong> (for example for uneven floors or large format tiles you might use a thicker bed).</p>

<p data-start="637" data-end="767">If you need a <strong data-start="651" data-end="663">5 mm bed</strong>, expect lower coverage — roughly <strong data-start="697" data-end="721">3–4 m² per 20 kg bag</strong> (industry norm for cement-based adhesives).</p>

backgrounds prior to applying tile adhesives or levelling and smoothing compounds. PrimeMore<br />
Universal regulates the porosity of the background, enhancing the workability, adhesion and<br />
strength of subsequently applied Kelmore products. When backgrounds are sufficiently primed<br />
using PrimeMore Universal, the surface finish of levelling and smoothing compounds will also be<br />
significantly improved. To help achieve total and uniform coverage, PrimeMore Universal is<br />
pigmented blue for enhanced visibility during application.</p>

										<content:encoded><![CDATA[<h1>Gypsum Board Adhesive &#8211; 1 x 1.1kg Bottles &#8211; Single Component Moisture Curing Polyurethane</h1>
<p>GypDeck Adhesive is specially formulated single component moisture curing polyurethane with excellent<br />
water resistant characteristics. The adhesive is used to bond the joints of gypsum boards, offering high strength and a high level of water resistance.</p>
<p><strong>1 x 1.1kg Bottles (covers 30m²)</strong></p>
<p>&nbsp;</p>
<p><span style="color: #282828"><strong>Preparation &amp; Application</strong></span></p>
<p>GypDeck Adhesive should be applied to the joints of the boards. It has an open time of 10 minutes once applied to allow all boards to be installed suitably before the adhesive starts to cure and set. Adhesive should be stored in the original container in a cool, dry place, at a temperature range of between 5°C and 25°C. In these conditions it has a storage life of 3 months.</p>
